WebMay 13, 2024 · The presence of tall, peaked P waves in lead II is a sign of right atrial enlargement, usually due to pulmonary hypertension (e.g. cor pulmonale from chronic respiratory disease). What causes P wave? The P wave occurs when the sinus node, also known as the sinoatrial node, creates an action potential that depolarizes the atria. WebPeaked P waves (> 0.25 mV) suggest right atrial enlargement, cor pulmonale, ( P pulmonale rhythm), [1] but have a low predictive value (~20%). [2] A P wave with increased amplitude can indicate hypokalemia. [3] It can also indicate right atrial enlargement. [4] A P wave with decreased amplitude can indicate hyperkalemia. [5]

WebAtrial enlargement: First, take another scan of p-waves in each lead, but pay most attention to the p-waves in Lead II and V1 (best leads to look in for p-waves!!). In Lead II, are the p-waves greater than 2.5 mm in height with a peaked look to them? If they do, you may have right atrial enlargement. Do the p-waves have a double peak and are ... WebApr 14, 2024 · The P wave is a composite deflection of the right and the left atrial depolarization. As sinoatrial node is situated in the right atrium, the right atrium depolarizes first, and the left atrium depolarizes later (Fig. 3.1a).However, in normal persons, the time difference in the depolarization of the two atria is not significant with the result that the P …
