Many people experience irregular heartbeats from time to time, noticeable mainly during various activities, such as exercise, bowel movements, eating, sex, stress, and even sleeping. Thankfully, irregular heartbeats can be easily diagnosed and serious heart problems can be prevented by simply recording the electrical activity of the heart with the help of an electrocardiograph or EKG machine.
What is EKG machine?
Electrocardiograph, also called EKG, ECG, or simply cardiograph, is a medical instrument used for detecting and diagnosing common heart abnormalities by measuring heartbeat triggering electric potentials on the body surface and recording electrical currents associated with activity of a heart muscle. In other words, EKG machine is a galvanometric device that variations or contractions in the electrical conduction system of the heart, thus evaluating the heart’s health. The working principle of EKG is: to pick up the cardiac tissue-generated electrical impulses (polarization & depolarization), translate those impulses into a waveform (electrocardiogram), which is then used to measure the following:
