Base on this point,we intend to study the feasibility of clinical application of low atrial septal pacing(Koch triangle) and compare with the traditional right atrial appendage pacing on long-term atrial tachyarrhythmia frequency by following up.

Recent therapeutical effects of septal pacing on the cardiac arrhythmia

Effects of septal pacing of right ventricular apex and right outflow tract on cardiac function and synchronization with left ventricular contraction

Objective: This study was designed to analyze the effects on the atrial electrophysiologic properries and the mecha-nism in treatment of atrial fibrillation with atrial pacing.

Right atrial appendage is the traditional site of atrial pacing,but with the development of physiological pacing,it was discovered that pacing this site repeatedly mought change the normal electrophysiology pathway, which led to biatrial electrical activity loss of synchronization and mought promote the atrial tachyarrhythmia frequency.
