英文摘要 | Postural tachycardia syndrome (POTS) is characterized by the development of orthostatic symptoms associated with a heart rate (HR) increments of 30 beat-per-minute (bpm) or greater without orthostatic hypotension. We report the skin sympathetic responses (SSR) in Chinese people with POTS. We enrolled 16 patients with POTS (five men and 11 women, age range, 21-57 years) and 16 healthy volunteers as controls (five men and 11 wonen, age range, 19-59 year) and performed SSR on both palms and soles simultaneously using electric stimulation at the wrist median nerve of each participant. The latency of SSR was more consistent among the healthy volunteers and patients, but marked variations in amplitude were noted between the two groups. Four out of the 16 patients displayed absence of SSR in soles and two in palms. The amplitude of SSR in soles was reduced in patients with POTS (P<0.005). There were significant differences in SSR latencies between the healthy volunteers and patients with POTS (P<0.05, in palms and P<0.005, in soles, respectively). We concluded that sympathetic sudomotor fibers are impaired in some Chinese patients with POTS and SSR may be a simple way to identify many patients with POTS with autonomic neuropathy. |
