Summary

During general anesthesia for surgery, doctors use an electrocardiogram (ECG)-a simple heart monitor-to check for problems like poor blood flow to the heart or irregular heartbeats. Normally, ECG stickers (called electrodes) go on both shoulders and the left side of the belly, right outside the heart area, to get clear readings.

But for shoulder surgery, these spots are in the way of the operation, so doctors often place them elsewhere, like on the breastbone instead of the shoulder. This can give fuzzy or wrong results, missing key changes in the patient's heart-good or bad-during surgery.

To fix this and better watch heart health in shoulder surgery patients, this study tests different ECG sticker spots: the usual ones, the common backup (like on the breastbone), and a new idea-placing them near both temples. Researchers hope to find which setup gives the most accurate heart readings to keep patients safer.

  • Monitoring During Anesthesia

Interventions

DEVICE

Standard

Standard ECG Lead II monitoring: Three electrodes placed on both clavicles below and left anterior superior iliac spine (outside heart boundary). Recorded simultaneously post-induction for at least 10 noise-free waves using Vital Recorder software to establish baseline ST segment morphology during general anesthesia."

DEVICE

mSC2

Modified Sternum-Chest Lead II ECG (mSC2): Electrode relocated to sternum center (replacing left shoulder), with right shoulder and left anterior superior iliac spine. Left-side version recorded post-induction; right-side post-surgery. Assesses ST segment similarity to standard for accurate ischemia detection in anesthesia.

DEVICE

mTC2

Modified Temple-Chest Lead II ECG (mTC2): Electrode relocated near temple (replacing left shoulder), with right shoulder and left anterior superior iliac spine. Left-side version recorded post-induction; right-side post-surgery. Evaluates ST segment morphology match to standard to enhance cardiac monitoring reliability.
