Ive had palpitations before. lately they've becom more frequent. maybe 2 times a week. feels like im out of breath when it happens. is that normal?

See your doctor: Palpitations can make you feel short of breath, for sure. Sometimes because blood flow is interrupted and sometimes because it just feels scary and induces anxiety. However, since you've had it for two weeks you should see your doctor and describe it. You need at least an EKG (heart tracing) and possibly some other tests; like a chest xray, and/or echocardiogram and labs.

See your doctor: Palpitations can be a rapid heart rate of no consequence or a potentially serious rhythm disturbance. It can be due to anxiety, extra heart beasts or even potentially serious heart rhythm disturbances. A heart monitor can help sort this out. Palpitations due to an arrhythmia can cause shortness of breath but breathing issues may be due to a related heart problem or anxiety. Get checked out.
