Blood pressure and heart rate at rest in the supine and standing positions were followed before, during and after irradiation for malignant tumours in 114 patients. A statistically significant gradual reduction in blood pressure during the treatment period was established. This was more marked in older patients and in patients with higher initial blood pressure but was not related to the region irradiated or the type of tumour treated. Particularly if the patient experiences vertigo and nausea on change of position, it seems advisable to check the blood pressure during treatment.
对114例恶性肿瘤患者在放疗前、放疗期间及放疗后，分别测量其仰卧位和站立位静息时的血压和心率。结果发现，治疗期间血压有统计学意义的逐渐下降。这种下降在老年患者和初始血压较高的患者中更为明显，但与照射部位或所治疗肿瘤的类型无关。特别是如果患者在体位改变时出现眩晕和恶心，在治疗期间检查血压似乎是明智的。
