Dronedarone was the best tolerated of the antiarrhythmic drugs, with the lowest rates of severe adverse events and a significant reduction in the risk of stroke. It is our practice to use propafenone, flecainide, sotalol, and dronedarone as first-line therapies in patients without structural heart disease (Table 4).17 Oca 2012
Read moreDoes atrial flutter require anticoagulation?
Most patients with atrial flutter should be considered for chronic anticoagulation in a manner similar to those with atrial fibrillation (AF). This recommendation is based not only on the fact atrial flutter carries a risk for systemic embolization but also that these patients usually have episodes of AF.
Read moreHow serious is polymorphic ventricular tachycardia?
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare condition. It causes an irregular heart rhythm that can be life threatening . It often shows up in childhood, but can show up later in life. The first sign is often fainting or near fainting during exercise or strong emotion.
Read moreHow do you manage polymorphic ventricular tachycardia?
Polymorphic VT in patients with a normal QT interval is treated in the same manner as monomorphic VT. If the patient has runs of polymorphic VT punctuated by sinus rhythm with QT prolongation, treatment is with magnesium sulfate, isoproterenol, pacing, or a combination thereof .
Read moreHow does polymorphic ventricular tachycardia happen?
Polymorphic VT generally indicates the presence of significant heart disease due to acute myocardial ischemia, cardiomyopathies, or a genetic arrhythmia syndrome (see what follows). Drugs causing QT prolongation and metabolic derangements are other causes (Fig.
Read moreWhat causes sustained ventricular tachycardia?
Ventricular tachycardia most often occurs when the heart muscle has been damaged and scar tissue creates abnormal electrical pathways in the ventricles. Causes include: Heart attack . Cardiomyopathy or heart failure.
Read moreWhat is sustained ventricular tachycardia?
Sustained VT is when the arrhythmia lasts for more than 30 seconds , otherwise the VT is called nonsustained. The rapid heartbeat doesn’t give your heart enough time to fill with blood before it contracts again. This can affect blood flow to the rest of your body.
