Invasive and non-invasive mapping of the cardiac electromechanical substrate in pulmonary arterial hypertension.
BACKGROUND Pulmonary hypertension (PH) is associated with right atrial (RA) and ventricular remodelling, predisposing patients to arrhythmias and adverse outcomes. Mechanistic insights into atrial and ventricular electrophysiology in PH may inform arrhythmia risk stratification and therapeutic strategies. OBJECTIVES...
