Symptomatic bradycardia due to total occlusion of left circumflex artery without electrocardiographic evidence of myocardial infarction at initial presentation.
We present the case of a 72-year-old man who was admitted due to low blood pressure and acute-onset dizziness with sinus bradyarrhythmia on electrocardiography. He had no obvious anginal symptoms, and there was no marked evidence of myocardial infarction. He was ultimately diagnosed with coronary artery disease with total occlusion of the left circumflex coronary artery, and he underwent successful coronary angioplasty after primary conduction disorders were ruled out.
