Electrical cardioversion is also very effective for atrial flutter, with about 90% of patients converting after synchronized shocks of as little as 25-50 J.Įven though the way the atrial contractile function is set up in this arrhythmia may protect against thrombus formation, the risk of thromboembolism is the same as with atrial fibrillation because these two arrhythmias often occur together. Ibutilide, a class III antiarrhythmic drug given through an IV, has been much more effective at stopping atrial flutter.Ībout 50–70% of patients return to sinus rhythm within 60–90 minutes after 1-2 mg of this agent is given through an IV. Changing atrial flutter to sinus rhythm with class I antiarrhythmic agents is also hard to do, and taking these drugs has been linked to a slowing of the atrial flutter rate to the point where 1:1 AV conduction can happen at rates higher than 200 beats per minute, leading to a collapse of the heart’s ability to pump blood. Treatment of atrial flutter – What is the best treatment for atrial flutter?Īgents used to control atrial fibrillation are also used to control the rate of the ventricles, but it is usually harder to do. See also Coarctation Of Aorta Diagnosis and Treatment Atrial Flutter Treatment and Management Guidelines Every second, third, or fourth impulse is sent to the ventricles through the AV node. The reentrant circuit makes the atria beat 250–350 times per minute. In the inferior leads of an ECG, atrial activity usually looks like a “sawtooth” (II, III, and AVF). ![]() In that case, the patient may show signs and symptoms of heart failure, such as shortness of breath, inability to exercise, and swelling, due to tachycardia-induced cardiomyopathy. ![]() However, suppose the arrhythmia goes unnoticed for a long time. Patients usually complain of heart palpitations, fatigue, or mild dizziness when they visit the doctor. Signs and symptoms of atrial flutter – What are some symptoms of atrial flutter? Catheter ablation is very effective and is thought to be the best treatment for typical atrial flutter.The chance of having a stroke is the same as with atrial fibrillation.ECG shows atrial activity has a “sawtooth” shape (rate 300 beats per minute). Rapid, regular tachycardia with a 2 to 1 block in the AV node and a heart rate of 150 beats per minute in the ventricles.See also Pulmonary Valve Regurgitation Symptoms and Treatment Atrial Flutter Diagnosis
