Question: Dr. Mokhtar, what are the possible causes of PVC's?

 MACtools_2 - Wed Mar 09, 2005 8:57 am

I have been diagnosed with PVC's, and will be seeing a specialist about it. I already have a call in to my primary care psysician to get the referral and appointment set up. However, I want to go into this all with some knowledge base.

I am an otherwise compltely healthy late-20's woman, on no medications except for birth control (Microgestin Fe 1.5/30). I eat well, sleep well, and exercise 3-4 times per week for 30 minutes.

I posted on this forum before regarding the fact that these pallpitations that I am feeling seem to have started when I started the Microgestin about 3 months ago -- my Ob/Gyn said there is no way that's the cause, the primary care physician said "I don't want to comment on that."

So, assuming it's NOT the birth control -- what are the other possible causes of PVC's? An extensive/exhaustive list would be most appreciated.

Thank you.

Hello!Here is the list of some causes of PVC.As you will see,there are all sorts of states,diseases and drugs that can cause PVC,but sometimes right reason is really hard to find.Sometimes impossible.

Other possible causes of PVC:
Acute myocardial infarction/ischemia
Cardiomyopathy, dilated or hypertrophic
Hypomagnesemia, hypokalemia, hypercalcemia
Mitral valve prolapse
Medications (eg, digoxin, sympathomimetics, tricyclic antidepressants, aminophylline, caffeine)
Illicit substances (eg, cocaine, amphetamines, alcohol, tobacco)

Quinn --

I appreciate your quick reply.

May I ask:

(1) what are your qualifications?
(2) What do you think of the idea of birth control pills causing the palpitations?

Thank you.

I am a general practice doctor from Croatia.I do not have much experience with the patients,but considering of what I know about antibaby pills,they do have the effect on cardiovascular system and maybe they can be a small part of your palpitation 's reason.
I would not recomend taking pills with PVC.But,you should consult your doctor.

Thank you again Quinn --
one of the things I am certainly going to try is to switch back to a BCP formulation that I used in the past that did not give me any symptoms. I am new to the Microgestin, and when I started taking it is when I started having the symptoms. When I used other BCP in the past, I never had any symptoms.

Qunn, you're the first doctor that has mentioned ANY possible connection between BCPs and palps.

My situation sounds similar to MACtools. I'm in my 20's, I exercise, and I was on nothing but Yasmin. Two weeks after I started to take Yasmin, I got the palps. I was hospilitized for a week and then diagnosed with PSVT. The whole time in the hospital I asked, should I stop the pill? They said it wasn't connected. It took me five days to stablize. I stopped taking the Yasmin after day four in the hospital.

My pharmicist believes that Yasmin could be part of the culprit. It has a direutic in it and I guess that can affect the heart (by screwing with potassium levels).

I don't think that myself, MACtools, and all the other women I've heard from about BCPs and heart palpitations are crazy and it's all in our heads.

I wish I could find a study out there that says, yes, some medications can cause Palpitations (or PSVT) - but I still haven't found it.
