Hi,
Welcome to HCM,
Premature atrial beats generally more common after the age of 50 years. This suggest that some underlying abnormalities in heart could be the cause, as heart diseases itself increases with age. it is said that as it increases during
pregnancy also, it could be related to
hormonal changes, but in my opinion, PAC's increases during pregnancy due to physiological changes in Heart not only due to hoemones, but also because of anatomical changes. Some other factors also can aggravate the frequency of PAC's, as coffee,
smoking, Alcohol, Sweeteners, Glutamate in various food ,
stress, obesity, lack of exercises. It is good that you are going to see your cardiologist. You should expect him to do full cardiac evaluation including 24 hours Holter Monitoring. If everything comes out normal, then your Doctor will suggest you the ways to deal with these symptoms. At the same time, you can go for annual cardiac evaluation.
Wish you good health.
