Atrial flutteris a macroreentrant arrhythmia. When it perpetuates in a counterclockwise direction around the atrial side of thetricuspid valve, which can be identified by the 12-lead ECG, it is called “typical”AFL. Typical AFL is cavotricuspid isthmus dependent, which means that the region exte...

Subjects relapsing while on sotalol had fewer symptoms than those on quinidine at the time of arrhythmia recurrence, presumably related to the lower heart rate. Sotalol has been evaluated for long-term heart rate control in sustained atrial fibrillation. In a double-blind, randomized trial, sotalol...
Class IC drugs are commonly used to maintain sinus rhythm in patients with AF, typically paroxysmal AF. Significantcoronary artery diseaseis a contraindication to their use because of an increased risk for proarrhythmia and sudden cardiac death. Because class IC agents increase AV nodal conduction, ...
If something other than an arrhythmia is causing heart palpitations, the treatment will depend on what it is. This can mean anti-anxiety medication and therapy for someone who has palpitations due to extreme anxiety, for example, or treatment for a condition such as hyperthyroidism or low blood...

sotalol and dofetilide prolong the QT interval and may cause proarrhythmia and torsades de pointes. Monitoring of the QT interval is therefore recommended when starting sotalol or dofetilide. [Hurst’s The Heart, 14th edition; Chapter 83, 20b.] Because of the risk for proarrhythmia, dofetili...

Hello, good people. My mother was diagnosed atrial flutter. I know that this kind of arrhythmia is not life threatening, but it can increase risk for a heart attack.
