Question: Referring to the ECG, the P wave represents: A) atrial contraction. B) ventricular relaxation. C) atrial depolarization. D) atrial repolarization. ECG: One common way of diagnosing heart conditions is through an Electrocardiogram ...
The P-wave is of atrial origin,while the Q, R,S, and T-waves are of ventricular origin.(a) The P-wave indicates atrial depolarisation.During this wave,the impulse ofcontraction is generated by the SA node.The PQ-wave represents atrial contraction.(b) The QR-wave is preceded by ...
Which of the following ECG tracings represents electricity flowing over the ventricles? a. P wave b. QRS wave c. T wave d. P-Q interval e. S-T interval Normally, the P wave rate and the QRS rate are ___ . Fill in the blanks. When the QRS co...
The main part of an ECG contains a P wave, QRS complex and T wave. Each will be explained individually in this tutorial, as will each segment and interval. The P wave indicates atrial depolarization. The QRS complex consists of a Q wave, R wave and S wave and represents ventricular depo...

P-wave: Atrial contraction PR interval: Represents the time taken for excitation to spread from the sino-atrial (SA) node across the atrium and down to the ventricular muscle via the bundle of His. QRS: Ventricular contraction ST segment: Ventricular relaxation ...
