WebDec 7, 2024 · A normal heartbeat on ECG will show the rate and rhythm of the contractions in the upper and lower chambers. The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers or ventricles. WebP wave indicate the depolarisation of Atrium. QRS indicates the depolarisation of ventricle. T wave indicates the Repolarisation of Ventricle.

WebThe P wave represents atrial contraction. P waves are normally evenly rounded and either positive or negative in all leads except V1, where a biphasic wave is sometimes seen. Its duration should be less than 0.12 seconds and its amplitude less than 0.25 mV. Right atrial hypertrophy (e.g., due to pulmonary hypertension) results in peaked P waves. WebCorrect option is A) An ECG consists of a set of three waves; these are namely the P wave, a QRS complex, and a T wave. Initiation of impulse by SA nodes and its travel through atria …

WebSecondly, amplitude of the P and QRS wave increases with increasing amount of exercise. This shows the stronger atrium contraction and ventricular contraction respectively. The physiological significance of the increase of heart rate is that more blood can be pumped to the skeletal muscles.
