[9] By approximating the shape of the left atrium as an ellipsoid, its volume can be calculated from measurements of its dimensions along three perpendicular directions. It is important to note that in patients with ischemic heart disease, wide Pwaves with a left atrium of normal dimensions can be observed, probably due to a delay of the atrial conduction. The mean left atrial dimension was 3.46 +/- 0.3 cm in normal individuals versus 4.04 +/- 0.3 cm in the hypertensive patients (p less than 0.01). If drug side effects are believed to be the cause, it is fundamental to judge the risk of terminatingdrug therapy as compared with implementing an artificial pacemaker in order to be able to continue drug therapy.
