P wave • LITFL • ECG Library Basics
2022年1月29日 · The P wave is the first positive deflection on the ECG and represents atrial depolarisation. Atrial abnormalities are most easily seen in the inferior leads (II, III and aVF) and lead V1, as the P waves are most prominent in these leads. The Atrial Waveform – …
The P Wave - My EKG
The P wave is the first deflection of the cardiac cycle seen on an EKG. It represents the electrical activity associated with atrial depolarization. The normal P wave is a low amplitude, vertical, rounded wave, resembling a gentle hill, which is continued immediately from the QRS complex.
ECG interpretation: Characteristics of the normal ECG (P-wave ...
ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex.
P wave (electrocardiography) - Wikipedia
In cardiology, the P wave on an electrocardiogram (ECG) represents atrial depolarization, which results in atrial contraction, or atrial systole. The P wave is a summation wave generated by the depolarization front as it transits the atria.

2023年7月24日 · The P wave and PR segment is an integral part of an electrocardiogram (ECG). It represents the electrical depolarization of the atria of the heart. It is typically a small positive deflection from the isoelectric baseline that occurs just before the QRS complex.
P Wave - The Definitive Guide - Biology Dictionary
2020年7月26日 · The P wave is the first wave on an electrocardiogram (ECG). It is followed by the PR interval, the QRS complex, the ST interval, and finally the T wave. By looking at an ECG P wave, cardiologists can translate results into healthy or unhealthy heart function.
Electrocardiogram Waves - My EKG
2024年5月19日 · P Wave. The P wave is the first wave of the cardiac cycle. It represents atrial depolarisation. It is the result of overlayiwg the electrical activity of both atria. It wave duration is less that 0.10 s (2.5 mm wide) and its maximum amplitude is 0.25 mV (2.5 mm height).
