Performance Testing of the Modified Electrocardiogram Lead Placement

Conditions studied: Monitoring During Anesthesia
In brief
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.
