What mimics ventricular tachycardia?

What mimics ventricular tachycardia?

Any supraventricular tachycardia (SVT), such as atrial flutter, sinus tachycardia, AV nodal re-entry tachycardia (AVNRT), or AV re-entry tachycardia (AVRT) with aberrancy, is probably the most difficult confounder of a monomorphic ventricular tachycardia when interpreting the ECG of a regular wide-complex tachycardia.

Can beta blockers treat ventricular tachycardia?

Furthermore, beta-blockers have been advocated for use in patients with ventricular fibrillation (VF) and ventricular tachycardia (VT), in whom these agents appear to reduce the incidence of recurrent ventricular tachyarrhythmias 6, 7.

How do you shock ventricular tachycardia?

Pulseless VT, in contrast to other unstable VT rhythms, is treated with immediate defibrillation. High-dose unsynchronized energy should be used. The initial shock dose on a biphasic defibrillator is 150-200 J, followed by an equal or higher shock dose for subsequent shocks.

Is VT life threatening?

Ventricular tachycardia (VT) is a fast, abnormal heart rate. It starts in your heart’s lower chambers, called the ventricles. VT is defined as 3 or more heartbeats in a row, at a rate of more than 100 beats a minute. If VT lasts for more than a few seconds at a time, it can become life-threatening.

What is slow ventricular tachycardia?

Slow ventricular tachycardia (slow VT) is a ventricular tachycardia (VT), in which heart rate is below the typical frequency of VT. We here report a case of acute liver failure in a patient with slow VT.

Does metoprolol stop ventricular tachycardia?

Metoprolol (200 mg/day) resulted in suppression of 60% of total premature ventricular beats, with couplets (pairs) and ventricular tachycardia decreased 84% and 94%, respectively (all p less than 0.01). Exercise-induced premature ventricular beats, especially ventricular tachycardia, were effectively suppressed.

Does metoprolol prevent ventricular tachycardia?

Are there any cases of atrial tachycardia with Multaq?

Reports of irregular heart rhythms on Multaq included 18 “potential” cases of bradycardia (abnormally low heart rate), 47 cases of atrial tachycardia (fast atrial heartbeat) and 13 cases of ventricular tachycardia (fast ventricular beats).

Why are some patients double dosed with Multaq?

Two were already taking beta blockers and their doctors did not decrease or discontinue these drugs when starting Multaq. Since Multaq has beta-blocking properties, those patients wound up being double-dosed. One of those cases occurred because the doctor was not there when the Multaq representative came to train the doctors in the practice.

What is the normal resting heart rate for ventricular tachycardia?

A normal resting heart rate is 60 to 100 beats per minute. Ventricular tachycardia starts in the heart’s lower chambers. Most patients who have ventricular tachycardia have a heart rate that is 170 beats per minute or more. Cleveland Clinic is a non-profit academic medical center.

Is it safe to take Multaq during pregnancy?

An important note for women: QuarterWatch reported that Multaq-linked birth defects had been found in animal studies and therefore Multaq has been classified as a pregnancy Category X drug whose risks outweigh the benefits during pregnancy. This means that women who are pregnant, or plan to become pregnant, should not take Multaq.
