About ECG 

Small electrodes are placed on the chest wall and connected to the ECG machine to allow recording of the heart’s electrical activity. This displays the heart’s electrical conduction system. It is a monitoring method and a routine test for cardiac problems. 

Preparation 

Some chest area may need to shave and cleaned to ensure good contact of electrodes. 

Results 

The ECG machine displays waveforms detected from your heart from 12 different directions. The waveforms represent electrical impulses which travel through your heart with each beat of the cardiac cycle.  

The Cardiologist can examine these impulses to assess the conduction system of the heart, whether the waves are regular or in the correct order. Varying waveforms may suggest underlying abnormalities which aid the Cardiologist in the detection of heart problems.
