ABSTRACT
Sick sinus syndrome (SSS) is a disease in which the SA node fails to perform the function of pacemaking. ECG shows various rhythms including sinus arrest. We report recurrent sinus arrest during laparoscopic sacral colpopexy in a 77-year-old female patient with SSS. The patient was diagnosed with SSS, but as there were no symptoms, the operation was performed without pacemaker implantation. After induction of anesthesia, vital signs were stable, but sinus arrest repeatedly appeared due to elevated vagal tone during uterine traction. After operation, the patient underwent pacemaker implantation, and to this day, she is doing well without any symptoms. The anesthesiologist should pay close attention to the progress of the operation through much communication with operator during the surgery. Also, we recommend to considering temporary pacemaker implantation for patients with SSS who undergo surgery that can increase vagal tone.
