¹Elevation of T1 or T2 values of the mid-septal myocardium. The numbers of T2-high or LGE represent the left ventricular segments.

CVS: Coronary vasospasm; HCM: Hypertrophic cardiomyopathy; VF: Ventricular fibrillation; MI: Myocardial infarction; CAD: Coronary artery disease; N/A: Not available; T2-high: High intensity on T2-weighted imaging; LGE: Late gadolinium enhancement; LVEF: Left ventricular ejection fraction; LVM: Left ventricular myocardial mass; LVEDV: Left ventricular end-diastolic volume; i: Indexed to body surface area; NSVT: Non-sustained ventricular tachycardia.
