高血压病心房过荷心电图表现

ELECTROCARDIOGRAPHIC SIGNS OF ATRIAL OVERLOAD IN HYPERFENSION

分析８２例高血压病人心电图。结果发现：Ｐ波增宽，Ｐ／Ｐ－Ｒ值增大，Ｐｔｆ负值增大，Ｐ－Ｓ４缩短的发生率高，且与病情平行，与心功能改变有一定联系，但不一定与Ａ（ＡＣＧ）和Ｓ４（ＰＣＧ）同步。

he aim of the study was to investigate the incidence of the ECG signs of atrial overload in hypertensive patients(HT) and its relationship to the state of the illness and cardiac function. ECG, mechanocardiogram and impedance cardiogram were performed in eightytwo HT and found P>0.10, P/P-R>1.6,P-S4 <140ms were more common (50%-73.2%) than PEP/LVET (46.3%) and DATI(29.1%). P/P-R=1.96±0.588 in Stage 1 of HT, 2.204±0.678 in Stage 2 showed that P/P-R had a definite relationship to the stage of disease (P<0.05). For those P-S4 were abnormal the PEP/LVET was increased and DATI decreased. All of these showed a simultaneity in ECG signs of atrial overload embodied the abnormal diastolic function of ventricle. In further analyses, P(ECG), A(ACG) and S4(PCG) may be changed but not keeping synchronous, so they can not be replaced with each other.
