Ventricular Tachycardia Treated with External Electric Countershock

open access: yesJAMA - Journal of the American Medical Association, 1963
ABSTRACT VENTRICULAR TACHYCARDIA is usually adequately controlled by various medications—procainamide hydrochloride and quinidine being the most effective. Recently external electric countershock has been recommended for patients failing to respond to drugs.1 This is a report of a man with a recent myocardial infarction who developed refractory ...

Termination of Ventricular Fibrillation in Man by Externally Applied Electric Countershock

open access: yesNew England Journal of Medicine, 1956
VENTRICULAR fibrillation is usually a rapidly fatal arrhythmia that may occur in cardiac patients, in any patient under anesthesia and in drowning and electrocution. In cardiac patients it is a frequent cause of sudden death in the course of coronary-artery disease, a well recognized mechanism of Stokes–Adams attacks, an uncommon toxic reaction to ...

Use of External Electric Countershock in the Treatment of Ventricular Tachycardia

open access: yesJAMA - Journal of the American Medical Association, 1961
ELECTRIC countershock applied to the closed chest has been successfully used to terminate ventricular fibrillation and prefibrillatory ventricular tachycardia. 1-3 Generally, this technique has been employed as an emergency measure in the unconscious patient with Adams-Stokes disease in the absence of other therapeutic alternatives. No reports exist on

Refractory ventricular tachycardia terminated by electric countershock

American Journal of Cardiology, 1963
Abstract A case of persistent ventricular tachycardia terminated by alternating current countershock is presented. The importance of electric countershock as a means of controlling refractory ventricular tachycardia in dire situations is discussed.

Response of cultured myocardial cells to countershock-type electric field stimulation

open access: yesAmerican Journal of Physiology-Heart and Circulatory Physiology, 1978
Myocardial cells isolated from 8-day chick embryos were grown in monolayer culture under conditions that produce “standard embryonic” and “adult-type” cells. These cells were subjected to electric field stimulation that had a waveshape and intensities similar to those used in clinical electric countershock procedures.

Ventricular fibrillation successfully treated by external electric countershock

American Journal of Cardiology, 1962
Abstract A 73 year old man with ventricular fibrillation was successfully treated with external electric countershock. The feasibility of effective external cardiac massage followed by defibrillation through the external application of electric countershock is illustrated.

Critical evaluation of indications for external electric countershock in the treatment of ventricular tachycardia

American Journal of Cardiology, 1963
Abstract External electric countershock has been recently employed and recommended for the treatment of ventricular tachycardia and other serious arrhythmias, when drug therapy is ineffective and the patient's condition desperate or intolerable. Two cases of ventricular tachycardia are reported in which the use of external countershock was regarded ...

Impedance to Defibrillation Countershock: Does an Optimal Impedance Exist?

open access: yesPACE - Pacing and Clinical Electrophysiology, 1995
Defibrillation is thought to occur because of changes in the transmembrane potential that are caused by current flow through the heart tissue. Impedance to electric countershock is an important parameter because it is determined by She magnitude and ...
