multifocal pvcs/vtach, and ekg question

Hi

Im a younger man with thickened mitral valve/+prolapse/+ some regurgatation.
I had a wpw accesory pathway in the anteroseptal area that conducted retrograde, in which i had a sucessful ablation.
I have dysautonomia, which is being controled now.
--------------------------------------------------------

Upon viewing my medical file and some of my rhythm strips from various recordings for diffrent arrythmias ive found these things which i was curious on, i had some rhythm strips and holter results that were never looked over by my doctor.


In almost all recordings i show multifocal pvc's, and quite a few sometimes at that, especially when in sinus tachycardia, i also show brief runs of monomorphic ventricular tachycardia at a average rate around 245bpm.  The v-tach runs are usually around 7 - 19 beats in length, i have had no previous MI.  Are these multifocal pvc's that occur very sporadically, a few one day...A very large amount another, only feel a few of them though, they kind of suck the wind out of me.
You put a holter on me and i probably could throw out anywhere from only 5 to 500 pvc's in a 24 hour period. I use no stimulants, no caffiene or cigarettes. Not overweight. Only take toprol.

In your opioion are these multifocal pvc's and runs of v-tach of any concern or significance in anyones case with my background?

In some of my EKG's it reads..

"non specific anterolateral T abnormalities...
T neg, T/QRS ratio <0.7 I, L, V2-V6"
i was in normal sinus rhythm, rate 100, normal p axis, Qtc 435.
I looked in lead V2, and the T waves are definatley inverted.

I know that inverted T waves sometimes is a indication of cardiac or previous cardiac ischemia...could you maybe explain to me what mine could be a indication(s) of, ive had it state similar on 1 other ekg, and then on some it was showing everything to be normal.
Thanks for the site.
Appreciate the info.

Dear Aero,
PVCs are very common and 5 to 500 PVCs in a 24 hour period is not generally cause for concern.  To help put it in perspective, today we saw a patient with 44,000 PVCs in a 24 hour period! The inverted T waves are most likely due to the previous WPW and are called 'memory T waves'.  They are not associated with ischemia.

I am sorry that this comment is not on the above subject - the system does not allow me to post a question anymore.
Here is a problem:
An ambulance is coming on an emergency call - heart attack.
Patients pulse is very weak, very low blood pressure and he is almost unconscious.
Here is a question:
Is the use of a defibrillator allowed in a case like that, or might it cause more damage to the heart??
