Question 3 (1 point) a 3 lead E CG uses electrodes Blank 1:

3-lead ECG (electrocardiogram) uses three electrodes to measure the electrical activity of the heart. These three electrodes are typically placed on the patient's chest, with one electrode placed on the right shoulder, one on the left shoulder, and one on the lower left side of the chest. The three leads (wires) connect the electrodes to the ECG machine, which then records the electrical signals generated by the heart. This information is used to diagnose various cardiac conditions and abnormalities.
