阻抗微分图可反映左室收缩功能、泵功能和周围血管阻力及顺应性等血液动力学指标,并间接反映左心室舒张功能。观察尼群地平一次口服前后血压及上述指标的变化,可了解尼群地平的降压疗效及对心功能的影响。本文将确认为Ⅰ、Ⅱ期高血压患者45例,按给药不同分为两组,尼群地平组(N组)22例(男17,女5),平均年龄60.64±8.42岁,SBP165.41±17.9mmHg(22.1±2.5 kPa),DBP 120.91±9.04 mmHg(16.21±1.2 kPa);Vit C组(C组)23例(男13,女10),平均年龄58.39±10.6岁。SBP 185±18.90mmHg(25±2.5 kPa),DBP104.80±
Impedance differential graph can reflect the left ventricular systolic function, pump function and peripheral vascular resistance and compliance and other hemodynamic parameters, and indirectly reflect the left ventricular diastolic function. Observed nitrendipine before and after oral administration of blood pressure and changes in these indicators can be understood nitrendipine antihypertensive efficacy and cardiac function. This article will be identified as Ⅰ, Ⅱ 45 cases of hypertension, according to the different administration divided into two groups, nitrendipine group (N group) 22 cases (male 17, female 5), mean age 60.64 ± 8.42 years, SBP165. 41 ± 17.9mmHg (22.1 ± 2.5kPa), DBP 120.91 ± 9.04mmHg (16.21 ± 1.2kPa); Vit C group (C group), 23 cases (13 male and 10 female). The mean age was 58.39 ± 10.6 years. SBP 185 ± 18.90 mmHg (25 ± 2.5 kPa), DBP 104.80 ±
