The heart can beat too fast (tachycardia), too slow (bradycardia), or irregularly. Normally, your heart works as a pump that brings blood to the lungs and the rest of the body.
Electrocardiography (ECG or EKG) is a painless, non-invasive procedure that records the heartâs electrical activity and can help diagnose arrhythmias. Arrhythmias are abnormal beats. The term arrhythmia refers to any change from the normal sequence of electrical impulses, causing abnormal heart rhythms.
