Patients will be given
drugs to help them relax, but they will still be awake.
Small electric catheters are inserted through a vein.
The catheters are placed in the upper and lower chambers
of the heart.
The catheters are hooked to
a recorder outside of the body that measures the electrical
impulses inside the heart. The doctor measures the speed
at which the impulses are traveling. The abnormal rhythm
is recreated so the team can observe it. Once the rhythm
is seen, treatment options are determined.
