The P Wave: Indicator of Atrial Enlargement

WebECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal. WebNov 1, 2024 · The P-wave begins at the sinoatrial node of the right atrium where it passes into the right and left atria. ... This indicates the depolarization of cardiac muscle cells from the center of the heart and into the ventricles.

WebJan 31, 2024 · What does an ECG show? If the heart is beating steadily, it will produce the typical ECG pattern: The first peak (P wave) shows how the electrical impulse (excitation) spreads across the two atria of the heart. The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax. WebApr 11, 2024 · The P-Wave It represents the electrical excitation (or depolarisation) of the atria, which leads to the contraction of both the atria.

For instance, If the ECG indicates possible coronary artery disease, a stress test or cardiac catheterization might be needed. WebMar 11, 2024 · The P wave. The P wave represents atrial depolarization. The normal P wave morphology is upright in leads I, II, and aVF, but it is inverted in lead aVR. The P wave is typically biphasic in lead V1 (positive-negative), but when the negative terminal component of the P wave exceeds 0.04 seconds in duration (equivalent to one small box), it is ...

WebP wave Small upwards deflection. Represents atrial depolarization. Action potential spreads from the SA node through contractile fibers in both atria QRS complex Begins as a downward deflection, continues as a large, upright, triangular wave, and ends as a downward wave. Represents rapid ventricular depolarization. WebThe point where the wave returns to the baseline marks the end of the P Wave. A QRS complex normally follows each P Wave. A normal sinus P Wave indicates that the electrical impulse responsible for the P Wave originated in the SA node and that normal depolarization of the right and left atria has occurred. SA node is the pacemaker site.
