case_images: EKG of the patient on admission. This EKG shows marked sinus bradycardia with borderline low voltage QRS (QRS amplitude max: 7 mm in limb leads and 8 mm in precordial leads; HR: 41 beats/min (R-R interval: 1460 ms); PR: 146 ms; QRS 76 ms; QT/QTc 518/427 ms).

case_images: The patient's electrocardiogram was remarkable for sinus bradycardia, with conserved axis and segment intervals and no other conduction abnormalities (Figure 1).
case_images: 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.
