Zero medical expertise here, but I would get into your PCP before the weekend. If she does need a cardiologist, your PCP can help get that appointment quicker than you alone.

Again, I'm the farthest thing from a doctor, but I would take baby aspirin until I figured it out.

Try pepcid first. Good test to see if it is heartburn. Myocarditis is not usually brief and intermittent but a basic blood test and EKG can test for it.

Acute onset chest pain 3-4 times a pain needs to be evaluated by a doctor with access to labs, ekg, etc. female patients can have a different presentation of cardiac related issues.

My wife wouldn't be touching that second shot. Heck she wouldn't have touched the first in your position.

Your wife already has known heart issues and took a vaccine that side effects is heart issues? And she is considering the second shot which tends to be more severe side effects than the first?

Would not touch with a 10 foot pole. But that's just our opinion.

Its amazing healthy people continue to get the shot for a disease that has a hospitizatiin rate under 1%.

She is subjecting herself to too many unknowns

Also I haven't heard of any pregnancy horror stories if you get covid. I have heard plenty of vaxx ones.

You are not getting a definite answer because there isn't one. There is small risk with either route so you have to decide which risk you want to take. As of today with your story I would stick to one dose Pfizer unless COVID starts to pop again as our rates are exceedingly low and the myocarditis risk goes up with the 2nd dose. It will likely hurt her long term immunity but that can be dealt with in 6 months to 6 years from now.

Medicine is not simple, there is rarely a 100% correct answer especially in more rare disease or new diseases.

And asymptomatic PVC's are not a pre-existing heart condition- they are normal everyone has them. The cardio concern is did something happen post vaccine that made them more frequent or symptomatic.

Y'all need to do what you think is right, but my personal opinion would be to skip the second shot, or at least delay. Only one shot should provide significant protection for some amount of time.

My wife and I are in a very similar situation. We're both 35, and she got pregnant in early July with our first. We went back and forth about the vaccine trying to decide if it was right for us. Ultimatley, during the height of the Delta variant, she decided she was ready to get the shot around 15 weeks of pregnancy just to help reduce the stress of going out and living our lives. We had read all the horror stories about pregnancies that have gone south due to Covid, and her Obstetrician recommended she get the shot after she had personally seen some bad reactions to Covid amongst her mothers, even one dying of complications. My wife also had a family friend who was a healthy 30 year old that got Covid while pregnant. They had to perform an emergency C-Section. They survived and thought she was getting better, so they sent her home. After getting home she all of a sudden took a turn for the worst and passed away.

I joined her in getting the Moderna shot a few weeks ago because I told her I wouldn't let her go through it alone. We only had a sore arm and potential insomnia for about a week after the first shot. We both kept waking up every night around 2 am and couldn't get back to sleep. We're due for our second round next Monday.
