The decrease in the SDRR:SD∂RR ratio indicates a reduction of cardiac sympathetic activity. However, CTS in patients having high SDRR:SD∂RR ratios can result in profound bradycardia.

Chemical thoracic sympathectomy (CTS) resulted in profound bradycardia
In the CTS group, however, the SDRR:SD∂RR ratio decreased significantly from 1.72 ± 0.20 to 1.23 ± 0.11 just after CTS. The previous patient, who had a high SDRR:SD∂RR ratio of 3.45 before CTS, exhibited severe bradycardia (22 beats/min).
The decrease in the SDRR:SD∂RR ratio indicates a reduction of cardiac sympathetic activity. However, CTS in patients having high SDRR:SD∂RR ratios can result in profound bradycardia.
