Pacemaker Mode Switching may Cause Potential Ventricular Tachycardia

LiBing Zhang1,2, Zhi Zhao1,2, Qi Jin1,2, Wei Fang1,2, Yuan Yang3, YongNan Fu1,2*

Patients with SSS are usually treated with a permanent pacemaker to control and improve symptoms. Here, we report a case of an implanted dual-chamber pacemaker with an automatic switching mode function due to Sick Sinus Syndrome (SSS) 8 years ago. The patient was admitted again because of Heart Failure (HF) symptoms. AT and hypokalemia occurred after admission, followed by Ventricular Tachycardia (VT). The prolongation of the QT interval caused by the change of pacemaker mode might be involved in the occurrence of VT. After emergency cardioversion, increasing ventricular pacing frequency, and correction of the hypokalemia, VT was well controlled and the patient was discharged from the hospital.
