Background:
Accessory pathways (APs) from the atrial appendage are uncommon and primarily described on the right side. Furthermore, connections involving the left atrial appendage (LAA) are even rarer.
Methods And Results:
This case report describes a 27-year-old female with recurrent supraventricular tachycardia (SVT) due to Wolff-Parkinson-White (WPW) syndrome. Electrophysiological evaluation identified dual atrioventricular (AV) connections: one from the LAA and another from the left coronary cusp (LCC).
Conclusion:
The electrical characteristics of WPW syndrome need a deeper understanding. The retrograde conduction can persist even after successfully eliminating the antegrade conduction.

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,...
