Ladies, if you are pregnant and you are experiencing palpitations or extra heartbeats, most of the time these are benign. Sometimes they can come from the top chambers of the heart. Sometimes they come from the bottom chambers of the heart.

Because of that, you can feel extra heartbeats and you can feel your heart racing. A lot of times this is not dangerous. It is dangerous though when you have things such as structural heart disease. If you’ve ever had valve problems, you’ve ever had a closure when you were a child, a congenital heart problem. These are things that you would need to follow with the cardiologist during your pregnancy, before and after delivery so we can monitor them. Now certainly if somebody is passing out or fainting, that might be a sign that you are having repeated arrhythmias or funny heart rhythms and that needs to be addressed by a specialist as well.
