《老友》专家门诊:我今年83岁,患有高血压、冠心病、阵发性房颤,平时坚持服药尚能控制病情。近几年来,我感到心跳加重,伴有心悸,尤其在晚上睡觉时更加明显。平时服安博维、络活喜、可达龙、阿司匹林、立普妥等,有时也吃中成药。我的心率较慢,平均每分钟50多次。有时服倍他乐克,心律更慢,但感觉心跳心悸好些。心脏彩超检查左心室稍有增大。请问:我这些症状是什么原因引起的,应如何防治? “Friends” expert clinic: I am 83 years old this year, suffering from high blood pressure, coronary heart disease, paroxysmal atrial fibrillation, usually insisted on taking medicine still able to control the disease.
