Noninvasive polygraphic tracings obtained at rest and during isometric hand-grip exercise were analysed in 67 healthy subjects. The purpose of the study was to determine the response of noninvasive polygraphic parameters to isometric exercise. During the third minute of sustained squeezing of a balloon dynamometer (30% of maximal voluntary contraction) a significant increase occurred in heart rate (+16.8 +/- 10.7 beats/min) an increase in both systolic and diastolic blood pressure (+3.4 +/- 1.6 kPa and 2.6 +/- 1.7 kPa respectively), increase in apexcardiographic index 100.a/D (+14.5 +/- 15.0% "D" amplitude), decrease of diastolic amplitude time index square root 2-c/(2-0) X (a/D) (-20.1 +/- 26.5), shortening of pulse transmission time (-0.006 +/- 0.005 s) and prolongation of cardiac cycle length corrected for left ventricular ejection time (+0.011 +/- 0.010 s) discussed. All these changes were statistically significant.
对67名健康受试者在静息状态和等长握力运动期间获得的无创多导记录进行了分析。该研究的目的是确定无创多导参数对等长运动的反应。在持续挤压气囊测力计的第三分钟（最大自主收缩的30%），心率显著增加（+16.8±10.7次/分钟），收缩压和舒张压均升高（分别为+3.4±1.6kPa和2.6±1.7kPa），心尖心动图指数100.a/D升高（“D”振幅增加+14.5±15.0%），舒张期振幅时间指数平方根2-c/(2-0)×(a/D)降低（-20.1±26.5），脉搏传输时间缩短（-0.006±0.005秒），以及经左心室射血时间校正的心动周期长度延长（+0.011±0.010秒）。所有这些变化均具有统计学意义。
