Arrhythmia Associated With Higher Mortality in Congential Heart Disease-Related PAH

The presence of arrhythmia in patients with pulmonary arterial hypertension (PAH) and Congenital Heart Disease (CHD) is associated with worse long-term outcomes, according to a study published in Heart.

In this retrospective study, investigators evaluated outcomes data of patients with PAH-CHD who attended a tertiary center between January 2007 and December 2015 (n=310; mean age, 34.9±12.3 years). Investigators followed patients for new-onset atrial or ventricular arrhythmia, as well as supraventricular arrhythmias, during a median follow-up period of 6.1 years. A supraventricular arrhythmia included atrial fibrillation and supraventricular tachycardia

The presence of arrhythmia was identified using follow-up electrocardiograms (ECGs) as well as ECGs during hospital stay, ambulatory ECG recordings, implantable loop recordings, and/or device interrogation.
