The ECG is the electrocardiogram used to determine the electrical activity of the heart.
The ECG is the is performed by placing different electrodes at different position on the chest. To make sure the ECG readings are accurate all the electrodes should be placed correctly on the chest.
The misplacement of the ECG electrodes are the main reason of the obtaining an incorrect ECG. Also, the interpretation should be done accurately according to the time versus electric activity graph.
