A 12-channel ECG machine is a type of electrocardiogram machine that can record the electrical activity of the heart from 12 different angles. This is achieved by using 10 electrodes placed on the patient's chest, arms, and legs. The electrodes are connected to the ECG machine, which then records the electrical impulses generated by the heart.
