Rhythm disorders are among the most prominent complications encountered by adults with CHD. Arrhythmias cause impaired quality of life, morbidity and mortality in adults with congenital heart diseases.

Objective: This study aimed to determine the incidence of arrhythmias in adult congenital heart disease patients in the Philippine Heart Center from 2000 to 2013.

Methods: This is a retrospective study reviewing adult patients with congenital heart diseases.

 Results: A total of 1164 patients were included from 2000 to 2013. Arrhythmias occurred highest in tetralogy of Fallot at 10% (n=7), atrial septal defect at 6.3% (n=74), ventricular septal defect at 6.3% (n=7), and patent ductus arteriosus at 3.8% (n=4).

 Conclusion: Atrial fibrillation has the highest incidence of arrhythmias across all groups of adult congenital heart diseases (ASD, VSD, PDA, and TOF) frequently seen in the Philippine Heart Center from 2000 to 2015. Ventricular tachycardia was seen in 18% of ASD and 14% of  VSD, Ventricular fibrillation was noted in 37.5% of cases, occurring mainly as procedure related and is more common in ASD. Supraventricular arrhythmias occurred in 16% of ASD and 14% of VSD. Heart blocks were seen in 34% of ASD and 50% of Tetralogy of Fallot.
