In an ECG the cardiac event corresponding to the ST segment is:
a) Atrial depolarisation
b) Ventricular depolarisation
c) Atrial repolarisation
d) Ventricular repolarisation

Correct Answer - D
PR – Interval corresponds with atrial depolarisation and conduction through AV node
QRS – corresponds with Ventricular depolarisation + atrial repolarisation
QT – corresponds with ventricular depolarisation + ventricular repolarisation
