The authors examined 100 psychiatric patients who were 60 years old and older for orthostatic hypotension and symptoms of dizziness and falling. Almost 40% of the patients complained of dizziness and falling, although only 27% had systolic orthostatic hypotension. Drug treatment, particularly the combination of tricyclics with other orthostatic hypotension-inducing drugs, was the most important factor accounting for the dizziness and falling. Underlying medical illness, particularly heart disease, also correlated significantly with the patients' symptoms.
作者对100名60岁及以上的精神科患者进行了直立性低血压以及头晕和跌倒症状的检查。近40%的患者主诉头晕和跌倒，尽管只有27%的患者有收缩期直立性低血压。药物治疗，尤其是三环类药物与其他导致直立性低血压药物的联合使用，是导致头晕和跌倒的最重要因素。基础疾病，尤其是心脏病，也与患者的症状显著相关。
