Having alot of palpitations tonight. like skipped beats. had them for years and had 100+ ecg heart tracings. i've had 2 24 hour heart monitor tapes done. i've had an ultrasound of my heart years ago. all normal. what if these are dangerous now?

The key is to be hooked up to a monitor while you're experiencing palpitations. What has the monitor demonstrated when you noted palpitations? If,at the time of symptoms, your heart rate& rhythm were normal, then your symptoms were most likely from forceful beats but no arrhythmia. If you've not had symptoms while on a monitor,get wired to an event monitor or one you can wear for weeks or months
