Management of VAs in athletes. nsVA, non-sustained ventricular arrhythmia—any VA lasting <30 s; sVA, sustained ventricular arrhythmia—ventricular tachycardia lasting ≥30 s and/or requiring intervention and/or ventricular fibrillation. Common premature ventricular complex (PVC) morphology: outflow tract/infundibular (LBBB morphology and inferior axis) and/or fascicular (typical RBBB morphology, superior/inferior axis, and QRS < 130 ms). Uncommon PVC morphology: all other types of PVCs. Short-coupled PVCs: PVC with interval from onset of preceding QRS to onset of PVC < 350 ms. SHD, structural heart disease; ICD, implantable cardioverter defibrillator; NSVT, non-sustained ventricular tachycardia; FHx SCD, family history of premature sudden cardiac death (male < 40 years, female < 50 years); FHx CM, family history of cardiomyopathy; EAM, electroanatomic mapping; RV, right ventricle; RVOT, right ventricular outflow tract; ILR, implantable loop recorder.
