—Lowenstein et al1 have contributed an interesting study of the role of alcohol in new-onset atrial fibrillation (AF). Although they appropriately pointed out its limitations, it is, altogether, a valuable report.

Indeed, notable arrhythmias with pericarditis do not occur unless there is accompanying heart disease or cardiac tamponade, which is tantamount to the same thing.2,3 This is not to say that there may
