“…This is not surprising considering the occasional effectiveness of a chest thump in reverting ventricular flutter (Pennington, Taylor, and Lown, 1970). Atrial flutter requires energy levels of 10 to 25 Ws (Guiney and Lown, 1972), and atrial fibrillation from 50 to 200 Ws.…”

Elective cardioversion with titrated energy was carried out under diazepam anaesthesia (38 procedures) in 26 patients on digitalis who presented with supraventricular or ventricular arrhythmias. Low energy shocks were given to establish the absence of latent digitalis intoxication, not unmasked by previous carotid sinus massage, and to restore sinus rhythm with the lowest possible energy discharge. In the absence of digitalis overdosage, titrated energy cardioversion restored sinus rhythm, at least temporarily, without dangerous ventricular arrhythmias. In one patient this precaution was neglected: a shock of 200 Ws provoked ventricular tachycardia. We present experimental and clinical evidence for the safety and effectiveness of titrated energy cardioversion in patients on digitalis.

“…Noting the previous work with DC defibrillation in humans by Gurvich in the Soviet Union and Peleška in Czechoslovakia, as well as the adverse effects of AC shock, in 1962 Lown et al reported their success in terminating VT with a single DC monophasic shock in 9 patients 38. Lown subsequently went on to expand DC cardioversion to successfully convert both atrial and ventricular arrhythmias using the monophasic DC shock 39–41. This success promptly resulted in the acceptance and worldwide spread of DC cardioversion.…”
