Comparison Between Symptomatic Individuals With Ventricular Pre‐Excitation in Resting ECG and No Electrocardiographic SVT Documentation With Symptomatic Individuals With SVT Documentation

Patient characteristics	Pre‐excited ECG with symptoms ‐ 30% (108/350)	Manifest SVT (AVNRT or AVRT) ‐ 70% (242/350)	P value
Age	33±16	44±17	<0.001
Women, n (%)	41%	71%	<0.001
Arrhythmia characteristics
Time between symptoms and ablation (mo), n (IQR)	36 (12–96)	72 (24–192)	<0.001
Medications before ablation, n (SD)	0.8±0.9	1.4±1.1	<0.001
Electrical cardiovertions, n (SD)	0.12±0.4	0.12±0.4	0.95
ER evaluations, n (IQR)	1 (0–3)	4 (2–10)	<0.001
SVT events in the month prior to ablation, n (IQR)	0 (0–2)	1 ( 0–2)	0.16

ER indicates emergency department; and SVT, supraventricular tachycardia.
