Hemodynamic Studies in Digitalis-Induced A-V Dissociation in the Dog*

摘要: Abstract A-V dissociation was studied by utilizing the intracardiac phonocardiogram, pressure pulses and electrocardiogram, in dogs that were intentionally overdigitalized with intravenous digoxin. Digitalis is capable of inducing can be reversed potassium chloride. Atrial activity maintains its independence this arrhythmia. The variable pattern atrial contraction while atrioventricular valves are open or closed demonstrated during dissociation.
