Abstract
A RECENT review of experience with the syndrome of short PR interval and abnormal ventricular complex occurring in otherwise healthy persons prone to paroxysmal tachycardia disclosed that a third of the cases were incorrectly diagnosed by the physicians who first saw them.1 This situation still prevails, as judged by the cases described below. The serious consequences of incorrect diagnosis are clearly demonstrated by these cases, all first seen within a period of a few months in 1957. The purpose of this report is to call attention to these errors, and to indicate how they may be avoided.Case ReportsCase . . .
