As direct-current conversion of cardiac arrhythmias is attaining ever increasing popularity, it is important to establish the effect of this procedure on the blood coagulation. The effect of electro-shock therapy on fibrinolysis^1,2 has been studied, but we are not aware of any previous coagulation studies on patients who have undergone closed "cardioversion." In order to evaluate this problem, euglobulin clot lysis³ determinations were done before and after direct-current cardioversion in 12 patients.

Materials and Methods.—

Twelve patients, who received direct-current shocks for the conversion of cardiac arrhythmias were included in this study. In all cases the same apparatus was used to deliver the electrical shock. The capacitor discharge was synchronized with the electrical activity of the heart and programmed to be delivered on the downstroke of the R wave. One electrode was placed over the sternum, and the other in the left midaxillary line. Routinely, 100 watt-seconds of . . . [Full Text PDF of this Article]
