Electrophysiologist says 6-8 flurry of beats<10sec not NSVT but palpitation and a person like myself with normal left ventricular function, is normal?

Sounds accurate. however the etiology of the palpitations has not been defined. Are the palpitations caused by Afib, USVT, SVT, etc. Once defined then they can be treated so you will sleep better at night.
