The P wave represents atrial depolarization, which originates in the SA node. The P wave has a lower amplitude and a more curved shape compared to QRS complex waves because of the slower depolarization magnitude and a slight delay in left atria (LA) depolarization compared to the right atria...
Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age. As noted above, the transition from...
P Wave – represents the movement of an electrical wave originating at the sinoatrial (SA) node and resulting in the depolarization of the left and right atria. P-R Segment – the pause in electrical activity caused by a delay in conduction of the electrical current at the atrioventricular (A...
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 Electrocardiogram Wave An ECG has three main components: the P wave, which denotes depolarising atria; theQRS complex, denotes the depolarization of the ventricles; and the T wave represents repolarising ventricles. During each pulse, a healthy heart has an ordered process of depolarization tha...
The P wave represents the spread of a stimulus through the atria (atrial depolarization). The QRS complex represents stimulus spread through the ventricles (ventricular depolarization). The ST segment and T wave represent the return of stimulated ventricular muscle to the resting state (ventricular re...
The final wave represents the return to a resting state for the ventricles. Which symptoms may require an ECG? ECG measurements are particularly important for people who presentthe symptoms of certain arrhythmiassuch as: • Chest pain • Shortness of breath ...
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 ...
3. What does the P wave represent? Depolarization of the atria Depolarization of the ventricles Represents the repolarization of the ventricles Depolarization of the atria and ventricles Answer:(a) 4. Which of these cannot be detected by an Electrocardiogram?
The P wave represents atrial depolarization. Atrial systole begins after the P-wave onset, lasts about 100 ms, and completes before ventricular systole begins. The QRS complex represents ventricular depolarization. The ventricular walls have more mass and are thicker than the atrial walls. This, alo...
