Background: Tachyarrhythmias are often refractory to management with antiarrhythmic drugs, catheter ablation provides effective long-term therapy. Its efficacy and safety is not assessed yet in details in our center.

Objectives: To study the efficacy and safety of cardiac electrophysiological procedures for patients with arrhythmia in Ibn Albitar hospital.

Methods: from February 2016 until November 2018, data from 561 consecutive procedures were analyzed for 545 patients with documented arrhythmias who have been underwent cardiac electrophysiological study with or without radiofrequency catheter ablation in Ibn Albitar Heart Center were included.

Results: Female gender was more predominant (338 patients 62%), mean age was 42.4±14, (range 8-93), 24 (4.4%) patients were above 65 years of age and 21 patients (3.9%) were below 18 years. Ablation was done in 522 (93%) procedures for 510 patients, with overall success rate was (94.7%) with no significant difference between the different age groups (p value=0.14). Atrioventricular nodal reciprocating tachycardia was the most predominant arrhythmias (370 cases 66%), accessory pathway related tachycardia (132 cases 23.5%), atrial tachycardia (24 cases 4.3%), atrial flutter/fibrillation (6 cases 1.1%), ventricular tachycardia / extrasystole (19 cases 3.4%), and (10 cases 1.8% were negative). Procedure-related complications occurred in 13 patients (2.3%), 3 patients (0.5%) had complete heart block requiring permanent pacemaker, 5 patients (0.9%) had transient heart block, 2 patients (0.4%) had pericardial effusion (one of them required pericardial aspiration) and 3 patients (0.5%) had deep venous thrombosis after the procedure.

Conclusions: The radiofrequency catheter ablation is an effective and safe method to manage patients with atrioventricular nodal reciprocating tachycardia, and accessory pathways in different age groups
