Abstract:
Clinico-electrocardiographical and electrophysiological features of noncoronarygenic ventricular arrhythmias are presented. Characteristics of localization of arrhythmogenic focus in various parts of left and right ventricular myocardium, in interventricular septum, and in immediate vicinity of each of 4 valves are discussed. Spectrum of necessary diagnostic measures is delineated, and assessment of efficacy of drug therapy is given. Characteristics of technique of endocardial mapping of noncoronarygenic ventricular heart rhythm disturbances are presented. Indications to radiofrequency catheter ablation, physical characteristics of radiofrequency intervention, effectiveness of catheter methods of treatment in dependence of localization of arrhythmogenic focus and spectrum of possible complications of the procedure are also discussed.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
