ECG electrodes will be connected to your chest. (Your
chest hair may need to be shaven). You will then be
strapped onto a tilt table with foot support. Next,
a small infusion line will be inserted on your hand
to provide intravenous access. Your ECG and blood pressure
will be monitored throughout the test.
The test is done in 3 stages:
Stage 1: Finger pressure will be applied
to an artery in the neck (the carotid artery), first
on the right side and then on the left side (carotid
sinus massage).
Stage 2: The tilt table will be tilted
upright to an angle of 60-70 degrees and you will remain
in that position for up to 18 minutes.
Stage 3: During this stage, which may
last for about 15 minutes, a drug (isoprenaline) will
be given via the intravenous line. The dosage will be
increased gradually so as to increase the heart rate
to a desired level.
You may experience some fast and strong heartbeats at
this point. The test will be terminated at any stage
when you experience giddiness or are about to faint
or on completion of the test.
At the end of the test, you will be returned to the
horizontal position. After a short rest, you may go
home or back to your normal activities. This procedure
will take about 1 hour.
