Alterations of acid-base balance, clearly defined as metabolic or respiratory in origin, were produced in anesthetized dogs; ventricular fibrillation thresholds were determined during these conditions. During metabolic acidosis, we found that the heart became more susceptible to ventricular fibrillation, as...
Method of defibrillating a heart A method of terminating ventricular fibrillation by the delivery of an asymmetric biphasic current pulse to three separate electrodes. A first catheter mounted electrode is located in the apex of the right ventricle (RV). A second elect......
2.3.1 Study 1: understanding the mechanisms of hemodynamic harm during simulated VT The pacing protocol aimed to help delineate the relative hemodynamic effect of the following: (1) heart rate, (2) atrioventricular synchrony, (3) biventricular synchrony, and (4) combined atrioventricular and biven...
Effects of Multisite Biventricular Pacing in Patients with Heart Failure and Intraventricular Conduction Delay. Background: One third of patients with chronic heart failure have electrocardiographic evidence of a major intraventricular conduction delay, which may wor... Cazeau,Serge,Leclercq,... - 《...
The changes in these parameters were detected before and during ventricular fibrillation with external and direct heart massage as well as after defibrillation. Comparisons were made between the effect of oxygen and room air ventilation. The ratio of successful resuscitation was 88% with direct heart ...
Many clinicians consider severe aortic stenosis to be a contraindication to pulmonary artery catheterisation, except during open heart surgery with cardiopulmonary bypass. This is due to the perceived high risk of arrhythmia, although the true incidence of ventricular tachycardia and fibrillation remains un...
Mathematical analysis of periodic and semiperiodic functions by the use of special electronic computers was applied to electrocardiographic recordings of ventricular fibrillation from hypothermic dogs. Preliminary experiments revealed a definite periodic component 1 to 3 min. after onset of fibrillation which...
