Abstract

We observed the motion of left ventricular posterior wall aortic root posterior wall in 20 normal persons and 20 patients with left ventricular hypertrophy during the period from March 1985 to Agust 1985. The results were as followings;
1) The percentage of rapid filling time to one cycle of heart beat obtained from the ventriculat posterior wall motion was significantly prolonged in patients with left ventricular hypertrophy(24.1±5.44%) than in normal persons(13.5±3.69%)(p<0.05) and that of slow filling time was significantly shortend in patients with left ventricular hypertrophy(27.4±6.10%) than in normal persons(38.7±9.06%)(P<0.005).
2) The rapid filling slop obtained from left ventricular postrior wall motion was significantly reduced in patients with left ventricular hypertrophy(44.0±12.45mm/sec)than in normal persons(91.7±53.16mm/sec)(P>0.005) but the slow were not signigficantly different between the two groups.
3) The left artial emptying index calculated from the aortic root posterior wall motion was significantly lower in patients with left ventricular hypertrophy(0.6±0.18) than in normal persons(1.1±0.26)(P<0.005).
