Cardiac Rhythm and Pacemaker
Pre-operatively all patients were in normal sinus rhythm except one
patient who had right bundle branch block (RBBB). In immediate
post-operative period 22 patients came in NSR, 4 patients developed left
bundle branch block (LBBB), in two patients it reverted to narrow QRS in
ICU whereas in two patients LBBB persisted in follow-up. The patient
having RBBB pre-operatively, developed complete heart block in immediate
post-operative period which recovered on 6thpost-operative day, but RBBB persisted.
