Complete heart block in pregnancy is relatively a rare problem. It may be congenital or acquired. Congenital complete heart block may be asymptomatic. Acquired causes may be secondary to cardiac surgery, rheumatic heart disease, infectious disorders. The goal in perioperative anaesthetic management of a case with complete heart block is to preserve the heart rate and maintain hemodynamic stability. Herein, we report the anaesthetic management of a case with congenital complete heart block using spinal anaesthesia and temporary pacemaker for elective lower segment caesarean section.
