This case report presents a patient with Takotsubo cardiomyopathy (TCM) and complete atrioventricular (AV) block who was treated with permanent pacemaker implantation. A 78-year-old woman with a history of hypertension presented with a 6-month history of palpitations. On initial evaluation, her heart rate was 40 beats/minute. Electrocardiography revealed a complete AV block and T-wave inversion in these leads: I, II, aVL, aVF, and V3-6. Echocardiography showed akinesis from the midventricle to the apex and hyperkinesis on the basal segments. The patient was diagnosed with TCM and complete AV block. Because improvement of TCM may subsequently improve the AV node dysfunction associated with TCM, the patient was admitted for treatment of heart failure without pacemaker implantation. The left ventricular (LV) abnormal wall motion improved gradually; however, the AV block persisted intermittently. On hospital day 14, a pause of 5-6 seconds without LV contraction was observed, and permanent pacemaker implantation was performed. On day 92, echocardiography revealed normal LV wall motion. However, electrocardiography revealed that the pacemaker rhythm with atrial sensing and ventricular pacing remained. Although specific degree of damage that may result from AV block associated with TCM is unknown, some of these patients require pacemaker implantation, despite improvement of abnormality in LV wall motion.
