Figure 2: End-systolic apical four-chamber view transthoracic echocardiogram showing (a) left ventricular ejection fraction 60% with end systolic volume 51 mL before pacemaker implantation, (b) Left ventricular ejection fraction 30% with end systolic volume 102 mL and severe diffuse hypokinesis 10 days after the procedure, (c) Color flow Doppler across the tricuspid valve showing mild tricuspid regurgitation, and (d) Continuous-wave Doppler of tricuspid regurgitation showing peak pulmonary artery systolic pressure of 51 mmHg
