There was no difference between PKP2 mutation-positive and mutation-negative individuals in sex, family history, history of sports activity, and arrhythmia (meaning cardiac arrest, syncope, ventricular tachycardia (VT), premature ventricular beats, supraventricular arrhythmias, ICD implantation, appropriate ICD interventions, and history of VT ablation) (see Table 2). Here, PKP2 is linked to ventricular tachycardia.
