Abstract


Ventricular activiation time and amplitude of left ventricular leads in 100 cases of hypertension (64 males, 36 females) and 37 cases of left ventricular hypertrophy proved by X-ray were studied.
1) Mean right ventricular activiation time in the cases of hypertension was 0.017(0.0080.024)sec. in Vl, and mean left ventricular activation time was 0.040(0.022--0.056)sec. in Vs, 0.042(0.0220.066) sec. in V 6.
Mean amplitude of left ventricular.´leads was 22.2(6.0-38.0) mm in RVs, 17.2(3.031.0)mm in RV6. and 36.105.056.0)mm in total ventricular potential.
2) In the cases of hypertension, it seemd to prolonged in ventricular activation time probably and more remarkable prolongation in cases of left ventricular hypertrophy proved by X-ray.
3) In the cases of hypertension, it revealed that left ventricular activation time was much influenced by systolic, or diastolic or mean blood pressure parallerly.
4) It was more reasonably interpreted that left ventricular potential are more to take 26 mm in RV6.
5) In the diagnosis of ventricular hypertrohpy, it was difficult to detected the high left ventricular potential alone, and was much reliable criteria when a tall R wave in Vs or V6 was associated with prolonged ventricular activation time.
6) In the primary diagnosis of ventricular hypertrophy, the electrocardiographic method was more effective means than X-ray method.
