Echocardiography is the most useful diagnostic test for Mitral Valve Prolapse. For more information, please see our As the left atrium depolarizes after the right atrium, an enlargement thereof will cause a longer duration of the depolarization time and therefore a widening of the Pwave, greater than 0.12s. Sometimes the right and left component of the Pwave are separated slightly giving the Pwave a form of "letterm" lower case, classically called Pmitrale. We conclude that echocardiographic left atrial enlargement may be an early sign of hypertensive heart disease in patients with no other discernible cause of left atrial enlargement. low voltage qrs The early repolarization pattern accompanied by concave ST segment elevation is seen in 25-40% of highly trained athletes; more common among males, black athletes and those with voltage criteria for LVH; usually seen in leads V5 and V6.
