Multiple meds and electrophysiology
by David M., Oct 27, 2000 12:00AM
Hello,
I'm trying to help an aunt with high blood pressure and heart disease who has also just had her thyroid removed recently. She was initially given these meds for blood pressure/heart disease:
Norvasc 10 mg QD
Catapres TTS-2 patch 1x per week
Avalide 300 mg QD
Toprol XL 50 mg QD
In addition, she was RX Levoxyl 125 mcg QD after her thyroid was removed. AFTER this med was given she started experiencing arrthymias, and she took it upon herself to stop a couple of the meds for a day or so to determine if they were the cause.
Is there any drug interactions with any of the above meds that may cause the irregular heartbeat?
Also, she is having an electrophysiology, to look into this, so I'm being told...What is this procedure exactly?
Thank you very much!
Dave

It is possible that she is on too much thyroid medication, and this can cause arrhythmias. Blood tests to measure thyroid levels can answer this question. An electrophysiology test is an invasive procedure that is like a cardiac catheterization, except it is used to measure electric currents inside the heart. It can be useful to investigate arrhythmias, but is only performed after noninvasive testing has failed to identify an arrhythmia.

As far as the EPS, I've had two. I'm sure the doctor will explain it when he answers your question and I think it's a very good idea for her to have this test and I was told it's fairly safe.
Electrophysiology Study (EPS) after
experiencing such a rapid heartbeat
at home that the paramedics gave me
three ivs and oxygen before transporting me to the hospital. After three days,
I had only one episode where my heart]
was racing and so they released me.
The doctor (who is a stranger tome)
suggested that I go immediately and have
this EPS study. My own physican wants
me to stay on the prescribed med,
Verapamil SA 240mg for about a month
before I decide to have any study done.
The medication seems to be working --
May I please have your professional
opinion to my quandry? I am 76 years
old - almost 77 but otherwise in tood
health. Thank you.
