ECG represents electrical activity recorded at the skin surface as a consequence of depolarisation and repolarisation
ECG is the most useful tool for assessment of cardiac rhythm.
Normal organised pattern of depolarisation and repolarisation of the heart leads to regular detectable potential differences between points on skin surface
