Electrocardiogram Parameters That Affect the Success Rate of Radiofrequency Ablation in Patients with Outflow Tract Ventricular Premature Complexes

Table 2

Comparison of VPC Origin and pleomorphic VPCs in patients with initially successful and failed RFCA ().

	Initially success	Failure	value
VPC origin			0.001
RVOT (%)	110 (80.9%)	8 (44.4%)
LVOT (%)	24 (17.6%)	7 (38.9%)
Both (%)	2 (1.5%)	3 (16.7%)
Pleomorphism (%)	20 (14.7%)	3 (16.7%)	0.734

, RVOT: right ventricular outflow tract; LVOT: light ventricular outflow tract.
