Abstract

amlodipine catheterization coronary artery disease electrocardiography syncope
A 68-year-old woman presented with 2 days of shortness of breath on exertion and fatigue. She denied syncope, chest pain, or leg swelling. She has known chronic obstructive pulmonary disease, type 2 diabetes, and hypertension. She underwent cardiac catheterization 1 year before this admission for concern for unstable angina, which showed nonobstructive coronary artery disease. She had normal left ventricular (LV) function by echocardiogram at that time and normal atrioventricular conduction. She has no known family history of cardiac disease or sudden death. She has no notable social history. She is on amlodipine and chlorthalidone for hypertension. Notable vitals included a pulse of 41 beats per minute and blood pressure 167/100. Physical examination was significant for nondistended jugular venous pressure with cannon a wave, variable S1, normal S2, and no murmurs. ECG revealed sinus rhythm, atrioventricular dissociation with ventricular escape rhythm at 36 bpm consistent with complete heart block (Figure 1).
