title: Alcohol consumption of patients with supraventricular tachyarrhythmias other than atrial fibrillation.
abstract: We studied the recent alcohol consumption and other possible precipitating factors in 99 consecutive patients (53 men and 46 women) all under 65 years of age with sustained re-entry and automatic supraventricular tachyarrhythmias and compared them with those of two groups of controls. One control group was derived from the Emergency Room patients and matched for age and sex; the other group (44 men, 22 women, mean age 48.7 years) was randomly selected from the general out-of-hospital population. There were 50 patients with supraventricular tachycardia, 30 with atrial flutter, and 19 with paroxysmal atrial tachycardia. Coronary heart disease (14% of patients), hypertension (10%), and dilated cardiomyopathy (6%) were the most prevalent cardiovascular diseases associated with the arrhythmias. The self-reported alcohol consumption of patients with arrhythmias during the week preceding the arrhythmia did not differ significantly from that of hospital or population controls, although significantly more patients than controls had liver enzyme levels above normal; neither were there any significant differences between the groups regarding prevalence for alcoholism as judged by the CAGE questionnaire. The results were essentially similar when patients with supraventricular tachycardia and those with intra-atrial tachyarrhythmias (flutter and paroxysmal tachycardia) were separately compared with the controls. We conclude that alcohol consumption, although a risk factor for atrial fibrillation, is not associated with the induction of other supraventricular tachyarrhythmias in patients of working age.
