Activin receptor-like kinase 4 haplodeficiency alleviates the cardiac inflammation and pacing-induced ventricular arrhythmias after myocardial infarction

ALK4 haplodeficiency ameliorates pacing-induced ventricular arrhythmias in MI mice. (A) Representative surface ECGs and intracardiac images of intracardiac electrical stimulation of WT and ALK4+/- MI mice. (B, C) VT/VF inducibility (B) and duration (C) of WT and ALK4+/- MI mice (n≥4).
