causal agents
ECG features


Lidocain can cause torsades, I believe, and it is usually due to progressive QT prolongation, followed by an insult (i.e. hypokalemia)

ECG shows a polymorphic ventricular tachycardia, with alternating R waves and Q waves, in a 'twisting of the points' configuration.

Rx is IV magnesium.


What is your source of information ?? would you pl let others know.Thanks


quinidine , terfenadine, diisopyramide, procainamide, amiodarone, cisapride r the drugs dat can cause torsades.
ecg------ prolongation of QT interval and ventricular ectopic beats
Tx - Mg


for causal agents + sotalol


sotalol is right


yes, sotalol Class III antiarrythmic...and then rest as mash said..



brethylium: classIII antiarrytmic
and tricycle antidepressant
in general, most anti arrythmics that block K+ channel delayed rectifier current lead to torsade de pointe
