Quiz About Your Heart! Know All About ECG
An electrocardiogram (ECG or EKG) records the electrical signal from your heart to check for different heart conditions. Electrodes are placed on your chest to record your heart's electrical signals, which cause your heart to beat. Electrocardiography is the process of producing an electrocardiogram.
