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) …
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, …
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 …
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 …
