Automated Assessment of Atrioventricular and Ventriculoatrial Conduction

摘要: A method discriminates between ventricular arrhythmia and supraventricular by determining the direction of an electrical signal conducted through atrioventricular node. An implantable cardiac defibrillator provides ventriculoatrial pacing bursts to determine if with a 1:1 atrial relationship is due tachycardia or tachycardia. This discrimination capability reduces incidence inappropriate shocks from dual-chamber defibrillators near zero differentially diagnose
