An electrocardiogram (ECG) is a basic test that can be utilized to check the heart 's rhythm and electrical signals. Sensors fixed to the skin are utilized to detect the electrical signals created by the heart every time it pulsates. These signals are recorded by an ECG and are diagnosed by a cardiologist or GP to check abnormalities or presence of heart disease. The ECG is commonly used by trained technicians to analyze and screen conditions influencing the heart. It can also be used to examine side effects of a possible heart issue such as chest pains, irregular heartbeat (palpitations), unsteadiness and shortness of breath. It is a quick, painless, non-invasive procedure which has no known risks.

Typically, the test includes connecting several little, sticky sensors called electrodes to your arms, legs and chest. These electrodes are linked by leads to an ECG recording machine. Prior to the electrodes are affixed, patient will be asked to expel the upper clothing, and occasionally any chest hairs, that would interrupt the electrical signals, may be shaved or cleaned. Once the electrodes are set up, the patient may be offered a gown to cover up. The whole procedure usually lasts a few minutes and patient can leave as soon as it has been carried out.
2.1 Types of ECG: (Heart, 2012)
Resting ECG
The resting ECG is performed while the patient rests for a couple of minutes on the couch. During the procedure, sensors are affixed to the patient 's arms and legs and also to the chest.
Stress Test (Exercise ECG)
Stress test is performed on patients who shows symptoms of heart problems during exercises or increasing levels of activity. The test is carried out by a trained technician to establish the amount of stress the heart can withstand before abdominal heart rhythms are displayed on electrocardiograph. The test involves either walking on a treadmill or riding a stationary bike at different rate of speed, while connected to the ECG machine. The test result can be used to determine whether exercise causes arrhythmias or exacerbates them or whether there is proof of insufficient blood flow to the heart muscle
