Effect of Tourniquet Use on ICEB and ICEBc in Upper Extremity Surgeries

Electrocardiography (ECG) is a non-invasive test used to measure the electrical activity of the heart. It involves placing electrodes on all four extremities and the chest area of the person and measuring the derivation between these electrodes. This procedure is painless and does not contain any elements that will disrupt the integrity of the body.
