Basically, everyone is a bit right here. The definitive way to treat it, after emergency treatment, is to determine the underlying cause. Is it congenital? Ot drug-induced. I have seen several cases of drug-induced, even thought I have read that it is rare, but maybe that's b/c I worked in a cardiac specialty hospital
I know, Duh!!
I found this great site w lists of the drugs that can cause it, it includes hormones, herbs (tho they may not be listed on the site), chemo drugs, etc...
This one was a short ditty, OK to paste, the next one was too long....
Torsades des pointes -- treatment
Torsades des pointes (twisting around the points) is a polymorphic VT associated by phasic changes in the amplitude and polarity of the ventricular complexes. It is often associated with a prolonged QT interval.
A variety of drugs and electrolyte disturbances can predispose to the arrhythmia:
Often resistant to traditional antiarrhythmic agents
Ventricular pacing to 100-120bpm to decrease the QT interval
Traditional antiarrhythmic therapy with lidocaine or procainamide
Discontinue potential offending drugs
Correct electrolyte abnormalities
