This case report presents a 100\u2010year\u2010old male with a history of atrial fibrillation (AF), left bundle branch block (LBBB), and ischemic heart disease, who was admitted with chest pain and episodes of bradycardia. After careful consideration, CRT\u2010P was successfully implanted. The patient\u2032s condition was closely monitored postimplantation, and a 4\u2010year follow\u2010up revealed significant symptomatic improvement and functional independence.
