Pacing at the posterosuperior bundle area preserves interatrial synchrony compared with right atrial appendage pacing: an echocardiographic study

Key Points

• The aim is to examine the effects of pacing at the posterosuperior bundle area on interatrial synchrony.
• Echocardiographic evaluation of interatrial synchrony during pacing.
• Comparison of posterosuperior bundle pacing with right atrial appendage pacing.
• Posterosuperior bundle pacing resulted in significantly better interatrial synchrony than right atrial appendage pacing.
