Electrophysiological Findings in Relation to Arrhythmia Presentation During Catheter Ablation Phase of the Hybrid Procedure

	N	Left PVs Isolated	Right PVs Isolated	All PVs Isolated	Posterior LA Exclusion
SR	39	32 (82.1%)	36 (92.3%)	29 (74.4%)	11 (28.2%)
SVA	11	8 (72.7%)	11 (100%)	8 (72.7%)	4 (36.4%)
P Value		NS	NS	NS	NS

LA indicates left atrium; N, number of patients; NS, not significant; PVs, pulmonary veins; SR, sinus rhythm at the beginning of the electrophysiological study; SVA, any ongoing supraventricular arrhythmia at the beginning of the electrophysiological study (namely, atrial flutter in 3 patients, atrial fibrillation in another 3 patients, and atrial tachycardia in 5 patients).
