The relativity between P wave terminal force in lead V1 and cardiac insufficiency
摘要
Abstract
Objective To investigate the clinical value of P wave terminal force in lead V1 (PtfV1 ) among patients with cardiac insufficiency and the relationship between PtfV1 and left ventricular ejection fraction (LVEF).Methods A total of 87 patients with cardiac insufficiency were selected as experi-mental group who had been admitted by the department of cardiology in our hospital.Another 85 cases of healthy people were enrolled as control group.We measured and calculated their PtfV1 in body surface ECG and LVEF in echocardiogram.The differences of the two indices were compared between experi-mental and control groups.At the same time,we compared the changes of PtfV1 in experimental group with mild,moderate and severe decline of LVEF[(40 50)%,(30 40)%,and (<30%)]respective-ly as well as the index separately between the three subgroups in experimental group and control group. Results (i)The LVEF value of experimental group was significantly lower than that of control group [(37.32 ±8.36)% vs.(60.79 ±6.56)%,P <0.05],and so was PtfV1 value [(-0.067 ±-0.021 )mm·s vs.(-0.017 ±-0.009)mm·s,P <0.05].(ii)Among the patients separately with mild,moderate and severe decline of LVEF,PtfV1 value orderly decreased [(-0.047 ±-0.007)mm·s,(-0.071 ±-0.010)mm·s,and (-0.095 ±-0.01 3)mm·s].The PtfV1 value in each of the three subgroups was lower than that in control group,with statistically significant difference(P <0.05).It indicated that PtfV1 reduced with the decrease of LVEF.Conclusion In the patients with cardiac insufficiency,PtfV1 declines significantly with the decrease of LVEF and the index is positively correlated with the severity of cardiac insufficiency.Therefore,PtfV1 can be applied in evaluating the severity of cardiac insufficiency as a practical index.关键词
