The term was officially introduced in by Ettinger et al for describing the occurrence of an acute cardiac rhythm disturbance in apparently healthy people after an episode of heavy drinking, i. Effect of whiskey on atrial less homework less stress and "holiday heart" observe a link between long-term alcohol consumption and AF. The trick was to take a clear position on.

With Congress always looking for ways to cut spending, agencies do not want to end a fiscal year with unobligated funds. In Washington it is hard for an agency to justify to lawmakers the need for more money if the money Congress appropriated last year—money the members of Congress had to explain to their constituents was needed then—was not used.

Accordingly, at the end of each fiscal year agencies resolve this dilemma by finding ways to close the gap between the portion of their appropriation obligated and the portion faced with becoming expired on September Too often that solution is a less than ideal procurement. The recent GAO report makes this year-end spending spree a little more concerning.

The individual contracts, however, can be substantial. What it found, among other things, is that of those 60 procurements, in only 23 did the procuring agency actually bother to get three or more prices or quotes from contractors—a fairly clear requirement in the FAR. Sometimes, agencies have a valid or at least excusable reason for not getting multiple prices or quotes from contractors. One reason is that some items the government purchases are simply not items widely available on the market.

In other words, for some procurements there just was not enough contractors who could supply the good or service sought. It is also associated with procoagulant changes after acute ingestion, hypocoagulation with chronic abuse, and thrombocytosis after withdrawal.

In addition, it can also reduce regional cerebral blood flow by affecting cerebral metabolism due to chronic abuse or lead to vasoconstriction of cerebral arteries with acute intake. All these aforementioned effects can lead to stroke, and regular abuse is also associated with intracranial hemorrhage, which can be fatal6. There is also a higher risk of sudden cardiac death with alcohol abuse, which increases with the amount ingested, regardless of the presence of previous heart events like ischemic heart disease or myocardial infarction5.

Chronic consumption of large amounts of alcohol is associated with alcoholic cardiomyopathy, a subtype of secondary dilated cardiomyopathy, known to be associated with not only cardiac failure but also with atrial fibrillation AF and other cardiac arrhythmias Alcohol appears to be able to cause cardiac arrhythmias in healthy people either following acute excessive alcohol ingestion, commonly known as "binge drinking," or chronic ingestion.

Arrhythmias due to binge drinking have been described as "Holiday heart syndrome" HHS and will be further discussed in this article. As alcohol consumption and binge drinking are common, it is important to illuminate the medical community and general population to the perils of HHS because the condition can be diagnosed more easily and preventive measures can be taken.

In addition, because it has been 34 years since the original description of HHS by Ettinger et al and questions surrounding this condition remain unanswered, we propose it is time to organize ideas and put things into perspective. We obtained articles from this main search. After analyzing each abstract, we identified 10 relevant papers concerning HHS and potential alcohol mechanisms behind its arrhythmogenicity.

Papers focusing only on chronic alcohol intake and its effects on cardiac function were not included. We also manually examined the reference lists from these identified articles for more relevant articles, repeating the process again, which resulted in four additional articles being added to our list. HHS: History and definition HHS was first recognized in the early 70's when Philip Ettinger noticed an association between acutely intoxicated patients and cardiac arrhythmias12,13, even though at that time most textbooks did not suggest that alcohol could cause cardiac arrhythmias in apparently healthy non-alcoholic individuals7.

The term was officially introduced in by Ettinger et al for describing the occurrence of an acute cardiac rhythm disturbance in apparently healthy people after an episode of heavy drinking, i.

These occurrences had the particularity of being more frequent after weekends or holidays like Christmas or New Year's Eve, which are known to be associated with increased alcohol ingestion, hence the name However, in a later study, Koskinen et al showed that this association between arrhythmias caused by recent alcohol intake and weekends or holidays was not always present HHS is mainly associated with supra ventricular arrhythmias, with AF being the most common cardiac arrhythmia in this syndrome.

However, other less frequent types of arrhythmias can also occur, such as atrial flutter, paroxysmal atrial tachycardia, and isolated ventricular premature beats HHS can occur in regular and non-regular drinkers. However because all the patients in Ettinger's study consumed alcoholic beverages heavily and on a regular basis, initially HHS was considered to be linked more to people with a background of chronic alcohol consumption than those without the background Nevertheless Ettinger et al14 also describe the case of a healthy non-regular drinker who presented with AF after alcohol consumption, hinting that HHS could also occur in this group of subjects.

This was later confirmed by other studies showing similar cases of sudden onset of cardiac arrhythmias after heavy drinking in non-alcoholic healthy people7, It is important to note that patients with HHS are apparently healthy, with no personal or family history of palpitations or other suggestive symptoms of structural cardiac anomalies or any clinical evidence of heart disease such as cardiomyopathy, cardiac valvular disease, coronary heart disease, or other conditions that could lead to cardiac arrhythmias, such as abnormal electrolyte levels or elevated thyroid hormone levels.

Laboratory and other tests are usually normal and after returning to normal sinus rhythm, the electrocardiograms are also mostly normal7, Another particular characteristic of HHS is the lack of new episodes with alcohol abstinence and the recurrence of symptoms with continued alcohol abuse. This observation further strengthens the role of alcohol in the development of these arrhythmias and also the importance of avoiding alcohol binging or consumption to prevent the occurrence of new events7,12,13, The most frequent symptom reported by patients with HHS is palpitations.

Other symptoms commonly reported are precordial pressure or pain, syncope14, and dyspnea7. However, it is important to note that cardiac arrhythmias, such as AF, can also occur without any clinical symptoms, making some episodes of HHS harder to diagnose, which can lead to an underestimation of its incidence AF, the most frequent cardiac arrhythmia in HHS, has been shown to be a major risk factor for stroke19 and increased mortality20, indirectly suggesting an association between HHS and stroke or death.

Nevertheless, there is no clinical data assessing these outcomes specifically in association with HHS. Moreover, arrhythmia associated with HHS after binge drinking can lead to sudden death, which may explain some of the sudden death cases commonly reported in alcoholics5, Pathophysiology The mechanisms behind the association of alcohol and cardiac arrhythmias remain unresolved. These may be direct alcohol myotoxicity or indirect by alcohol derived metabolites or effects on other organs such as adrenal glands.

However, there are some facts about alcohol arrhythmogenic properties that have been accepted among the scientific community Figure 2. Cardiac conduction interference: It is believed that acute alcohol ingestion interferes with the cardiac conduction system through slowing of conduction, which is important because it facilitates re-entry, which is one of main mechanisms underlying the development of cardiac arrhythmias, namely AF.

In an experimental study with dogs, Ettinger et al21 did not observe prolongation of the HV interval or QRS widening after acute alcohol infusion. However, these parameters were only measured in two dogs. A bigger sample, namely one composed of humans, may be necessary to confirm this theory. Cardy et al23 have also shown prolongation of P and QRS waves in 13 humans after acute ingestion of alcohol, suggesting atrial and ventricular slowing of conduction due to alcohol.

Although controls also showed prolongation of these waves, changes in the alcohol group were significantly more pronounced. This may happen directly or even indirectly since the inhibition of sodium channels can increase sodium-calcium-exchanger activity, prolonging the action potential and repolarization, with subsequent prolongation of intervals, such as the QT interval, thereby facilitating the onset of cardiac arrhythmias. Refractory period shortening: Alcohol can shorten the atrial refractory period, which can lead to cardiac arrhythmias in rat atrial tissue However, in a study of 11 alcohol abusers, Engel et al.

Therefore, there can be additional and significant focal conduction changes that can facilitate re-entry and lead to the cardiac arrhythmias observed in this study Increased sympathetic activity: Alcohol can increase the release of catecholamines, secreted by the adrenal gland medulla or locally by the myocardium itself7, This increase of systemic and intramyocardial catecholamines can lead to the prolongation of P-waves, which is known to be associated with atrial arrhythmias8,9.

However, Maki et al26 did not find a significant increase of catecholamine levels after alcohol consumption in individuals with or without a personal history of AF episodes caused by binge drinking. Yet, catecholamine levels in the AF group displayed a trend toward being higher, which can synergistically work with the other arrhythmogenic mechanisms of alcohol, increasing the likelihood of cardiac arrhythmias.

The same authors observed an increase of beta-adrenergic receptors along with a predominance of cardiac sympathetic activity in patients with a previous drinking-related AF history Rise in plasma free fatty acids: With alcohol intake there is a rise in plasma free fatty acids, which are believed to be arrhythmogenic in nature7,9.

Although the mechanisms are still not completely understood, a significant association between elevated free fatty acids and AF was observed in elderly people in a recent analysis of the Cardiovascular Health Study, strengthening this theory Acetaldehyde arrhythmogenic effects: The primary metabolite of alcohol also appears to exhibit arrhythmogenic properties, possibly by increasing systemic and intramyocardial catecholamines23, An experimental study by Gallardo-Carpentier et al28, using dog Purkinje fibers, has shown that acetaldehyde has an arrythmogenic effect, which appears to be caused by an increase in adrenergic activity.

Hence, acetaldehyde could cause the onset of arrhythmias some time after alcohol ingestion. Conversely, arrhythmia has been observed shortly after whisky intake even before significant amounts of acetaldehyde could be produced Recommendation: To address the inconsistencies in the NRSROs' methodologies for calculating required performance statistics and total outstanding ratings for initial and updated Form NRSRO filings, address limitations in the required 10 percent and percent rating history disclosures, and increase the comparability and usefulness of these disclosures, the Chairman of the Securities and Exchange Commission should, for the disclosures of required performance statistics, evaluate the appropriateness of SEC's currently designated asset classes for presenting performance statistics, and where SEC determines that the asset classes are not appropriate, modify the requirements accordingly.

Since the original description of HHS, 34 years have passed and new research in this field has increased the volume of knowledge related to this syndrome. Ingestion below these levels had the same risk as non-drinkers Another point to consider is that chronic drinkers may be more prone to binge drinking during holidays, weekends, or other special occasions. The same study followed-up some of the patients, verifying relapses in all those who continued alcohol abuse, which strengthens the motivation to suggest abstinence as a prophylactic measure.

While SEC had registered 10 of 11 credit rating agency applicants as of July , some staff memoranda to the Commission summarizing their review of applications described concerns that were not addressed prior to registration. These micro-structural and cardiac conduction changes may facilitate the occurrence of HHS after a binge drinking episode.

Accordingly, at the end of each fiscal year agencies resolve this dilemma by finding ways to close the gap between the portion of their appropriation obligated and the portion faced with becoming expired on September However, in another recent meta-analysis, by Kodama et al18, apart from observing a dose-response relationship similar to the previously cited meta-analysis, their data also suggested that moderate intake could produce a higher risk of AF compared with not drinking at all. During admission of a patient with palpitations or other symptoms associated with cardiac arrhythmias, a high suspicion of HHS should occur if the patient exhibits signs of alcoholic intoxication or had a recent episode of binge drinking.

Among the cardiovascular effects, regular alcohol abuse appears to increase blood pressure, leading to arterial hypertension, which by itself is a risk factor for other cardiovascular diseases4 and for sudden death5. Conversely, arrhythmia has been observed shortly after whisky intake even before significant amounts of acetaldehyde could be produced Refractory period shortening: Alcohol can shorten the atrial refractory period, which can lead to cardiac arrhythmias in rat atrial tissue Cardy et al23 have also shown prolongation of P and QRS waves in 13 humans after acute ingestion of alcohol, suggesting atrial and ventricular slowing of conduction due to alcohol. Sources of Funding There were no external funding sources for this study. A case series by Thornton7 showed four cases of cardiac arrhythmia after alcohol intake in persons who did not consume alcohol regularly.
