What is an electrocardiogram, and what do the P wave, the QRS complex and the T wave represent?
Original Khojo Papers practice question — not from a past board paper.
Answer
An electrocardiogram is a record of the electrical activity of the heart taken from the surface of the body. The P wave represents atrial depolarisation, the QRS complex ventricular depolarisation, and the T wave ventricular repolarisation.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Atrial repolarisation is hidden within the QRS complex.
