Other related information
We analyzed the clinical characteristics of the patients, electrocardiographic and electro-physiology properties of the ATs, and results of the CA. For each patient, the data were ob-tained from the patient chart, body surface electrocardiograms before, during and after the electrophysiology study, 24-hour Holter monitoring, echocardiography, and intracardiac electrograms during the electrophysiology study.
