Lidocaine (a class Ib antiarrhythmic drug) shortens the QT interval and may be effective especially for drug-induced torsades de pointes. Class Ia, Ic, and III Torsades de pointes, torsade de pointes or torsades des pointes (TdP) (/ t ɔː ˌ s ɑː d d ə ˈ p w æ̃ t /, French: [tɔʁsad də pwɛ̃t̪], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.

By acceleration of the heart rate, the QT interval is shortened, thus preventing the recurrence of the arrhythmia. Treatment of torsade de pointes includes: isoproterenol infusion, cardiac pacing, and intravenous atropine. Torsades de pointes (TdP) is a rare form of tachycardia arrhythmia where the heart’s two lower chambers beat faster than, and out of sync with, the two upper chambers. Typically, TdP resolves without intervention or treatment.

Treatment: Conservative discontinue all QT prolonging drugs. indication for all patients; outcomes torsades de pointes due to drugs typically do not recur after withdrawal of the drug For drug-refractory torsades de pointes, transvenous ventricular pacing at rapid rates will shorten the QT interval, eliminate the pauses that precipitate torsades, and prevent further bursts of arrhythmias.

If a drug is the cause, it is stopped, but until drug clearance is complete, patients with frequent or long runs of torsades de pointes ventricular tachycardia require treatment to shorten the QT interval. 2020-08-10 · Torsades de Pointes is slightly different from ventricular fibrillation in that it can spontaneously resolve. However, Torsades de Pointes can ultimately progress into venticular fibrillation if left untreated.

Se hela listan på patient.info Lidocaine (a class Ib antiarrhythmic drug) shortens the QT interval and may be effective especially for drug-induced torsades de pointes. Class Ia, Ic, and III antiarrhythmics are avoided. If a drug is the cause, it is stopped, but until drug clearance is complete, patients with frequent or long runs of torsades de pointes ventricular tachycardia require treatment to shorten the QT interval.
