This causes the refractory period of atrial tissue to increase, hence its effectiveness in the treatment of atrial fibrillation and atrial flutter. Dofetilide does not affect dV/dT max (the slope of the upstroke of phase 0 depolarization), conduction velocity, or the resting membrane potential.
Reduce ventricular rate in patients with atrial fibrillation; V Adenosine; Digoxin; Magnesium sulfate; Work by other or unknown mechanisms Contraindicated in ventricular arrhythmias; Adenosine is used to treat supraventricular tachycardias, especially in heart failure and atrial fibrillation [9]
Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria . Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures , are used.
Vagal maneuvers, such as the Valsalva maneuver, are often used as the initial treatment. [4] If not effective and the person has a normal blood pressure the medication adenosine may be tried. [4] If adenosine is not effective a calcium channel blocker or beta blocker may be used. [4] Otherwise synchronized cardioversion is the treatment. [4]
