目的探讨不同年龄段高血压患者心电图及经颅多普勒的变化特征。方法对不同年龄段高血压患者共140例行心电图及经颅多普勒检查。结果老年组与非老年组心电图(ECG)的变化特征均以ST一T改变、左室肥厚、心律失常占前三位。经颅多普勒(TCD)的变化特征的变化均以脑动脉血流速度不同程度加快为主。同时发现老年组ECG和TCD异常检出率分别为71.4%,92%;非老年组分别为43%,60%,老年组显著高于非老年组(P<0.001)。结论老年组与非老年组高血压患者心脏和脑血管等靶器官损伤后的ECG与TCD表现相似,老年高血压患者ECG和TCD异常改变的发生率明显高于非老年组。
Objective To investigate the changes of ECG and transcranial Doppler in hypertensive patients of different ages. Methods A total of 140 patients with hypertensive patients of different ages were examined by electrocardiogram and transcranial Doppler. Results The changes of electrocardiogram (ECG) in elderly group and non-elderly group were all changed by ST-T, left ventricular hypertrophy and arrhythmia accounted for the top three. Transcranial Doppler (TCD) changes in the characteristics of changes in the cerebral blood flow velocity to speed up the main changes. The detection rates of abnormal ECG and TCD in the elderly group were 71.4% and 92% respectively, while those in the non-elderly group were 43% and 60% respectively, which were significantly higher in the elderly group than in the non-elderly group (P <0.001). Conclusion The ECG and TCD of heart and cerebrovascular target organs in elderly patients and non-elderly patients with hypertension are similar. The incidence of ECG and TCD abnormalities in elderly hypertensive patients is significantly higher than that in non-elderly patients.
