What your ETS or ESB surgeon will not tell you during the consultation:
T(2)-T(3) ganglionectomy significantly decreases pulse rate and systolic blood pressure, reduces myocardial oxygen demand, increases left ventricular ejection fraction and prolongs Q-T interval. A certain loss of lung volume and decrease of pulmonary diffusion capacity for CO result from sympathectomy. Histomorphological muscle changes and neuro-histochemical and biochemical effects have also been observed.
Clin Auton Res. 2003 Dec;13 Suppl 1:I40-4.
Instead, you will be told:
"Usually the surgery is used to treat sweating in the palms or face. The surgery stops or turns off the nerve signals that tell the part of the body to sweat too much."

or this:"The procedure turns off the signal that tells the body to sweat excessively. It is usually done on patients whose palms sweat much more heavily than normal."
or this:"This method does not involve the cutting of the sympathetic nerves. Instead, the surgeon interrupts their activity by applying a titanium clamp to the nerve, thus stopping their activity. The clamp exerts pressure on the nerve and the signals the nerve produces don’t reach the sympathetic nerve endings. This is method that has a positive effect in the sense that the sympathetic ganglia are not destroyed. This leaves the patient with the possibility of having the nerves reconstructed in the future by simply removing the titanium clamp."

All the above statements are carefully crafted to make the surgery appear harmless, easy and safe. Yet, ETS and ESB procedures disrupt the nerve signals not only to the sweat glands but other structures and systems in the body, most notably the heart, resulting in Bradycardia in patients, who are unaware that they are signing up for a surgery that potentially will impact on their neurocardiology.
