[Left axis deviation and left anterior hemiblock in patients with essential hypertension during antihypertensive treatment (author's transl)].
The ECG's of 127 patients (81 men and 46 women) with uncomplicated essential hypertension were evaluated over a 4-year period of antihypertensive treatment. At the beginning of the study in 1973, 39 men (48%) showed ECG changes of left axis derivation (LAD) and 8 men (10%) a left anterior hemiblock (LAH), while 19 women (41) showed a LAD and 4 (9%) a LAH. During the course of the study no changes were noted in the 12 cases of LAH. However, two additional men developed signs of LAD in 1975/76 and one more in 1977/78. Men with LAH were somewhat older and women with LAH heavier in comparison to the total group. The combination of LAD and left ventricular hypertrophy (LVH) was evident in 9 men (11%) and 4 women (9%) at the beginning of the study, while 6 men (7%) and 1 woman showed a combination of LAH and LVH. Reversibility of LVH by ECG was observed in 10 patients (50%), but no concomitant changes in axis deviation were seen.
