Right atrial enlargement produces a peaked P wave ( P pulmonale) with amplitude: > 2.5 mm in the inferior leads (II, III and AVF) > 1.5 mm in V1 and V2. The prolapse may be due to ischemic damage (caused by decreased blood flow as a result of coronary artery disease) to the papillary muscles attached to the chordae tendineae or to functional changes in the myocardium. Such a P-wave is calledP pulmonalebecause pulmonary disease is the most common cause (Figure1). The normal Pwave measures less than 2.5mm (0.25mV) in height and less than 0.12s in length (3small squares). Interatrial blocks. Simple guide to reading and reporting an EKG step by step.

In these cases, it is the morphology of the P wave in lead V1 that allows us to determine if there is a left atrial enlargement associated with interatrial block. However, studies that have found LAE to be a predictor for mortality recognize the need for more standardized left atrium measurements than those found in an echo-cardiogram. Normally taking a b complex vi Left atrial enlargement itself has no symptoms. It may be used as a complement to echo for a more precise look at the heart valves and heart muscle, or in preparation for heart valve surgery. As forventricular enlargement, the ECG cannot differentiate dilatation from hypertrophy, which is why some experts have suggested that the termatrial abnormality be used instead of enlargement. The echo sound waves create an image on the monitor as an ultrasound transducer is passed over the heart.
