目的探讨糖尿病自主神经病变患者直立倾斜试验的特点及其对阳性结果的影响。方法对72例因晕厥就诊的糖尿病自主神经病变患者在安静环境下进行直立倾斜试验,观察其心率、血压变化。结果试验阳性率为87.5%,其中血管抑制型9例,心脏抑制型51例,混合型3例,阴性9例。实验开始后各型心率均呈现逐渐上升的趋势,但心脏抑制型的峰值提前出现,在晕厥前各型心率均明显上升而后在晕厥时快速回落。结论糖尿病自主神经病变患者晕厥主要为心脏抑制型,晕厥前心率变化可以作为直立倾斜试验阳性的预测指标。
Objective To investigate the characteristics of orthostatic tilt in patients with diabetic autonomic neuropathy and its effect on the positive results. Methods 72 patients with diabetic autonomic neuropathy treated by syncope were tested for upright tilt in a quiet environment, and their heart rate and blood pressure were observed. Results The positive rate of the experiment was 87.5%, including 9 cases of vascular suppression, 51 cases of cardiac inhibition, 3 cases mixed and 9 cases negative. After the start of the experiment, all kinds of heart rate showed a gradual upward trend, but the peak of cardiac inhibitory appeared in advance, before the onset of various types of heart rate were significantly increased and then quickly fell in syncope. Conclusions Diabetic patients with autonomic neuropathy syncope mainly cardiac inhibition type, before the onset of syncope heart rate can be used as a positive tilt prediction test.
