To the Editor:—
In the communication by Rabbino, Likoff, and Dreifus on complications and limitations of direct-current precordial countershock (JAMA190:417 [Nov 2] 1964) there are three examples of ventricular fibrillation.The preshock electrocardiographic tracing of case 1 is described in the text and in Fig 1 as paroxysmal atrial tachycardia with 2:1 atrioventricular block. A close examination of the tracing, however, reveals a double tachycardia, with a regular atrial rate of 250 beats per minute, and a regular nodal mechanism at 150 beats per minute, with complete dissociation and heart block. It seems necessary to correct this error since a final list of indications and contraindications for this valuable form of therapy must take into account the exact electrocardiographic mechanism of the arrhythmia.
