in 1978, ettinger et al conducted a study evaluating 32 separate dysrhythmic episodes in 24 patients. These patients consumed alcohol heavily and regularly; in addition, they took part in a weekend or holiday drinking binge immediately prior to evaluation. Based on the results of this study, the term holiday heart syndrome was coined. It was defined as an acute cardiac rhythm and/or conduction disturbance, most commonly supraventricular tachyarrhythmia, associated with heavy ethanol consumption in a person without other clinical evidence of heart disease. Typically, this resolved rapidly with spontaneous recovery during subsequent abstinence from alcohol use.1
thanks, that was interesting.
