Successful treatment of systemic sclerosis complicated by ventricular tachycardia with a cardiac resynchronization therapy-defibrillator: A case report

Figure 4 Echocardiogram. Echocardiogram pre-operation showed a normal left ventricular ejection fraction of 58% and normal cardiac chamber size with no structural abnormality of both ventricles. LVPWs: Left ventricular posterior wall systolic thickness; LVPW: Left ventricular posterior wall; LVs mass: Left ventricular end-systolic mass; LVIDs: Left ventricle internal diameter at end-systole; ESV: End-systolic volume; EF: Ejection fraction; FS: Fractional shortening; SV: Systolic volume; IVSs: Interventricular septum end-systolic thickness; IVS: Interventricular septum.
