Heart & Cardiology/When are EP studies recommended?


Hi Dr Richardson,

I've had both rapid heart beats (ie; pulse from 85-105) and sometimes bouts of skipped beats....I've had the whole workup (test wise) having had 2 echos, cardiac MRI, Holter monitor study, tons of blood work - all is normal...

1. When are EP studies done, these aren't done everytime a patient has rapid heart beats/skipped beats are they?....Who benefits most from EP studies?


Hello Rick,

Ep studies are recommended in preparation for an intervention, like ablating atrial fib.  They are not recommended for skipped beats or for normal sinus tachycardia like your 85 -105.  Skipped beats are normal heart activity, easy to understand as normal from knowledge of the heart's electrical system and occurring in about half of us.  They don't mean you have heart disease or will in the future develop heart disease or any cardiac catastrophe.

Please write back if this note doesn’t answer all your questions.
