Key result
General anesthesia without prophylactic pacing succeeds in asymptomatic congenital complete heart block with chronotropic competence.
Why the study?
Does general anesthesia without prophylactic temporary pacemaker insertion allow safe performance of non-cardiac surgery in adult patients with asymptomatic congenital complete heart block and a narrow QRS complex?
Case Report (n=1)
No
Does general anesthesia without prophylactic temporary pacemaker insertion allow safe performance of non-cardiac surgery in adult patients with asymptomatic congenital complete heart block and a narrow QRS complex?
General anesthesia for non-cardiac surgery may be performed without a prophylactic temporary pacemaker in patients with asymptomatic congenital complete heart block and a narrow QRS complex, potentially guided by preoperative chronotropic competence testing.
No takes yet. Share an insight, caveat, or question.
Should not yet change practice in asymptomatic congenital complete heart block; supports hypothesis that chronotropic competence may guide avoidance of prophylactic pacing but requires validation.
Barry Swerdlow (2018) conducted a case report in Asymptomatic congenital complete heart block (n=1). General anesthesia without prophylactic temporary pacemaker was evaluated on Successful completion of surgery without temporary pacemaker. An adult patient with asymptomatic congenital complete heart block and documented preoperative chronotropic competence successfully underwent general anesthesia for non-cardiac surgery without a prophylactic temporary pacemaker.
