<h3>What does an EKG machine do?</h3>
To check for various cardiac diseases, an electrocardiogram (ECG or EKG) measures the electrical signal from the heart. Electrodes are positioned on the chest to capture the electrical impulses that drive the heartbeat. The signals are displayed as waves on a computer monitor or printer that is connected. EKG provides details about your heart's rhythm and pace, as well as whether your heart has enlarged owing to hypertension or has signs of a past heart attack (myocardial infarction).
The EKG is written down on regular paper that is moving at a speed of 25 mm per second. The paper is cut into huge squares that are each 5 mm wide, or 0.2 s, in size. On the EKG, a wandering baseline artifact appears as a sluggish, undulating baseline. It may be brought on by the patient's breathing or other movements.
