Voltage‐Associated Abdominal Pain During Bedside Temporary Transvenous Pacing: A Case Report

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.
