ECG

An ECG test is a test that checks for issues with the electrical activity of the heart during expansion and contraction. The ECG test machine is the machine that records the activity taking place and displays it in the form of waves. Doctors frequently use dips and spikes in readings to interpret the overall health of the heart and body. Your heart should beat at 60 to 100 beats per minute. An ECG test can be used to determine if the heart is beating properly, or if the heartbeat is not within the safe range, then the patient is suffering from arrhythmia.

When people do an ECG test after complaining about chest pains, it helps doctors determine if the pain is coming from the heart or from another organ in the body. An ECG test can also help doctors determine other heart problems like imbalances in the blood chemicals that control heart activity, cardiac arrest taking place, inflammation of the heart, poor blood supply to the heart, congenital defects involving the electrical systems of the heart, and enlargements of the heart.

The ECG test is conducted by placing electrodes on the limbs and chest of the patient. A gel is applied to the spots where the electrodes have to be connected. Often, hairy patients who take an ECG test have to have the hair from their bodies shaved off before placing the electrodes, as it could interfere with recording heart activity at the ECG centre. The procedure is non-invasive and safe for everyone.
