Solution
Electrocardiogram is the instrument used to record potential differences of heart muscles. To make an $ECG$ recording, the patient lies quietly on his/her back on a table. Lead is placed on certain spots on the patient's chest. It is generally performed with six leads placed over the heart and three leads placed at certain points (one on each upper arm and one below a knee is common).
