Other known causes of sinus tachycardia must be excluded â these include anaemia, hyperthyroidism, phaeochromocytoma, diabetes induced autonomic dysfunction, fever, and dehydration; Sometimes an EP study will be performed to exclude atrial tachycardia before an IST diagnosis is finally made.

Carpal tunnel. In the human body, the carpal tunnel or carpal canal is the passageway on the palmar side of the wrist that connects the forearm to the hand. The tunnel is bounded by the bones of the wrist and flexor retinaculum from connective tissue. Normally several tendons from the flexor group of forearm muscles and the median nerve pass through it. There are described cases of variable median artery occurrence.
Dr. Reid Abrams discusses carpel tunnel syndrome. Carpal tunnel syndrome (CTS) is a condition in which the median nerve is compressed as it passes through an opening from the wrist to the hand called the carpal tunnel. The carpal tunnel is about 1Â½ inches long and is located at the base of the hand near the wrist.
