The patient's electrocardiogram was remarkable for sinus bradycardia, with conserved axis and segment intervals and no other conduction abnormalities (Figure 1).
Systolic (a) and diastolic (b) apical 4 chamber transthoracic echocardiographic images. Ejection fraction estimated to be 62%. No regional wall abnormalities or valve pathology was described.
