I'm new to this site so I hope everyone who posted about PVC's sees this. I have had problems with my heart for 20 yrs. It all came to a head last summer with lots of other problems. The most dramatic were the over 58,000 pvc's in a 24 hour period. I was having chest pains and out of breath. After years of cardiologist, it was my massage therapist who finally diagnosed me correctly. I had an over active thyroid.
Your thyroid controls everything in your body. If you have a weakness, such as your heart, the thyroid can make things much worse.
I am still having pvc's but nothing like they were. Exercise makes you feel better because it speeds up your heart and helps balance out the pvc's.
I still need to find a doctor that can help me with them.
