Chapter 6: The Electrophysiology Laboratory

The electrophysiology laboratory is a unique place for the diagnosis and treatment of cardiac arrhythmias. In general, it is an invasive laboratory very similar to the cardiac catheterization laboratory. The laboratory should be electrically isolated (free of outside electrical noise), since in addition to recording standard body surface electrocardiograms, high-fidelity intracardiac electrograms (recordings from inside the myocardium) are recorded.

The lab contains a fluoroscopy table that in some cases may be able to tilt the head upward as well as downward (as in the Trendelenburg position, in which the feet are raised above the head to help pool venous blood back into the central circulation). The tilting motion may be helpful in gaining access to the blood vessels in order to insert catheter and/or introducer sheaths.

It is also helpful if the patient has low blood pressure. In some laboratories, the table can tilt upward at least 60 degrees to facilitate head-up tilt-table testing (the procedure to diagnose vasovagal syncope or neurocardiogenic syncope). This table should be able to tilt rapidly up and down, and it should be stable enough to accommodate the weight of the patient.
