A new semantic mining approach for detecting ventricular tachycardia and ventricular fibrillation
Accurately differentiating between ventricular fibrillation (VF) and ventricular tachycardia (VT) episodes is crucial in preventing potentially fatal misinterpretations. If VT is misinterpreted as VF, the patient will receive an unnecessary shock that could damage the heart; conversely, if VF is incorrectly interpreted as VT, the result will be life-threatening. In this study, a new method call...
متن کاملVentricular Fibrillation
The cellular events during the initiation and maintenance of ventricular fibrillation (VF) are poorly understood. We developed a nonischemic, isolated, perfused rabbit Langendorff preparation in which sustained VF could be induced by alternating current (AC) and which allowed changes in perfusate composition. We also used Na+-K+ pump inhibition (10 ,uM ouabain or K'-free perfusate) to induce VF...
متن کاملIdiopathic Ventricular Fibrillation
Sudden cardiac arrest (SCA) and sudden cardiac death (SCD) are disastrous outcomes of various predominant cardiac diseases. The leading cause of SCA and SCD is coronary artery disease. However, SCA/SCD in young patients is mainly caused by congenital disorders of primary arrhythmic or structural origin. SCD is defined as death from an unexpected circulatory arrest, usually because of a cardiac ...
متن کاملHuman Ventricular Fibrillation
Amajor controversy in cardiac electrophysiology is whether ventricular fibrillation (VF) is maintained by wandering wavelets or mother rotors. On the basis of a computer model of atrial fibrillation by Moe1 developed in 1962, fibrillation was hypothesized to be maintained by multiple small, wandering wavelets, in which the activation pattern is constantly changing. According to the wandering wa...
متن کاملModification of Ventricular Fibrillation
Abrupt occlusion of the left anterior descending coronary artery was performed on 43x unanesthetized farm pigs in order to evaluate the relative effects on the latency to ventricular fibrillation (\VFL) of 1 ) adaptation of the animals to the laboratory, and 2) beta-receptor blockade by propranolol. Compared to control values, VFL, was greatly lengthened (i.e., VF delayed or prevented) by adapt...
