A 59-year-old caucasian consulted our clinic with symptoms of dizziness and exertional syncope. The combination of myocardial hypertrophy diagnosed by echocardiography, together with a history of peripheral neuropathy made us suspect cardiac amyloidosis which was later proven by endomyocardial biopsy. A graded exercise test and two Holter monitoring studies revealed neither rhythm nor conduction abnormalities. A head-up tilt test revealed a vasovagal vasodepressor response.
一名59岁的白种人因头晕和劳力性晕厥症状前来我们诊所就诊。超声心动图诊断为心肌肥厚,再加上有周围神经病变史,这使我们怀疑是心脏淀粉样变性,后来经心内膜活检得到证实。分级运动试验和两次动态心电图监测研究均未发现节律或传导异常。直立倾斜试验显示血管迷走性血管减压反应。
