Why the study?
Does artificially controlled heart rate (auricular or ventricular driving) prevent ventricular fibrillation in dogs subjected to hypothermia?
Does artificially controlled heart rate (auricular or ventricular driving) prevent ventricular fibrillation in dogs subjected to hypothermia?
Artificially controlling heart rate via auricular or ventricular driving does not prevent ventricular fibrillation during hypothermia in dogs, suggesting S-A nodal or A-V conduction abnormalities are not the primary cause.
Artificially paced rates fail to avert ventricular fibrillation during canine hypothermia; leaves open conduction defects as arrhythmia trigger.
