WebFeb 15, 2024 · The P wave on an ECG trace is indicative of atrial depolarisation, which may be initiated by the sinoatrial node or by an ectopic atrial focus. Normal P Wave Size … WebP Wave. It is important to remember that the P wave represents the sequential activation of the right and left atria, and it is common to see notched or biphasic P waves of right and left atrial activation. P duration < 0.12 sec; P amplitude < 2.5 mm; Frontal plane P wave axis: 0° to +75° May see notched P waves in frontal plane ; QRS Complex

WebJan 4, 2024 · An S wave, or shear wave, is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving. What does a small S wave indicate? You will also have seen a small negative wave following the large R wave. This is known as an S wave and represents depolarisation in the Purkinje fibres. WebJul 25, 2024 · 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 …
WebApr 26, 2024 · The P wave is a summation wave, which means that it is electrical activity caused by many places signalling simultaneously, resulting in wave-like contractions. … WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size.
WebWhat does an enlarged P wave mean? If the p-wave is enlarged, the atria are enlarged. If the P wave is inverted, it is most likely an ectopic atrial rhythm not originating from the sinus node. Altered P wave morphology is seen in left or right atrial enlargement. The PTa segment can be used to diagnose pericarditis or atrial infarction.
