Small p wave meaning

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. WebP waves indicate the result of atrial activation and may be broadly classified as concentric or eccentric. A P wave morphology identical to a sinus P wave suggests sinus tachycardia, inappropriate sinus tachycardia, sinoatrial nodal reentrant tachycardia, or AT arising close to the region of the sinus node. What is normal P value in ECG?

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. WebThe P wave is a small deflection wave that represents atrial depolarization. PR interval The PR interval is the time between the first deflection of the P wave and the first deflection of the QRS complex.
