Background: Primary focal hyperhidrosis is characterized by overactivity of the sympathetic nervous function, and this has been effectively treated with endoscopic thoracic sympathetic denervation (ESD). The imbalance of sympathetic and parasympathetic nervous system that’s created by ESD may affect the heart, lung and other thoracic organs. We analyzed the heart rate and ECG changes after performing ESD at our hospital, and this is the first such study that has been conducted on this.
Material and Method: Of the 263 patients who underwent ESD between October 1996 and October 2006, 130 had ECG before and after ESD, and they were classified into 3 groups according to the level of ESD: Group I (n=40) patients underwent ESD at the 2nd rib (T2ESD), Group II (n=80) at the 3rd rib (T3ESD) and Group III (n=10) at the 4th rib (T4ESD).
Result: There was no mortality or major morbidity. Heart rate (HR) was significantly decreased from 71.6±10.6/min to 66.8±10.2/min after ESD (p＜0.01); however, the PR (from 148.6±21.2 msec to 152.8±20.5 msec) and QTc (from 399.2±15.4 msec to 404.0±15.1 msec) intervals were significantly increased after ESD in the patients who suffered with primary hyperhidrosis (p＜0.01). According to the level of ESD, there were significant changes in the HR and QTc interval in group I (T2ESD), the HR and PR interval in group II and the QTc interval in Group III.
Conclusion: There were significant changes in the heart rate and ECG findings after ESD. The thoracic sympathetic denervation of T2, T3 and T4 affected the electrical activity of the heart at the resting state.
