What helps with irregular heartbeats?

Lifestyle Changes: First - get evaluated by a cardiologist. If you smoke - stop. Limit alcohol, limit caffeine, limit use of stimulants. If none of these work you may need medication.

The right diagnosis: The best way to diagnose palpitations is to record them. Your doctor can prescribe a monitor that you can wear which will allow your heart rhythm to be recorded. The recorded rhythm during your symptoms will be very helpful in getting to the bottom of it. Only then can the right treatment (medicines or otherwise) be started.
