A high pacing threshold with voltage-dependent abdominal pain during transvenous pacing suggests inadvertent coronary sinus lead placement, requiring complete withdrawal and repositioning.
Voltage-associated abdominal pain during temporary pacing is a clinical sign of inadvertent coronary sinus lead placement, which can be corrected by lead repositioning.

Abstract A high pacing threshold accompanied by voltage‐dependent abdominal pain should raise suspicion of inadvertent coronary sinus lead placement. In such cases, complete withdrawal and re‐advancement of the lead should be considered. As complementary tools, intracavitary ECG and transthoracic echocardiography may be used to confirm correct lead positioning and ensure stable capture.
