Typically, the AV conduction ratio is 1:1 , that is, a QRS complex follows each P wave. First degree AV block usually produces no symptoms in the patient. However, this condition can progress to a higher degree AV block. Because this condition may get worse, patients are usually observed carefully.

Who Gets Atrial Flutter?
Read moreWhat is atrial flutter with variable conduction?
Atrial flutter, a supraventricular arrhythmia , is one of the most common rhythm disturbances of the heart. It is characterized by a fast atrial rate with a fixed or variable ventricular rate. There are several atrial contractions to one ventricular contraction and symptoms include fatigue, palpitations, and syncope.
Read moreIs AV conduction normal in atrial flutter?
Atrial flutter is usually paroxysmal and only rarely chronic. Untreated persons with atrial flutter and no disease of the AV junction usually have a 2:1 AV conduction response with an atrial rate of about 300 beats/min and a ventricular rate of 150 beats/min. Over time, atrial flutter usually degenerates into AF.
Read moreWhat is a flutter on ECG?
Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute ; the atrial rate in atrial fibrillation is 400 to 600 bpm.
Read moreWhat is a flutter rate?
Atrial flutter results from an abnormal circuit inside the right atrium, or upper chamber of your heart. It beats extra fast, about 250-400 beats per minute . A normal heartbeat is 60-100 beats per minute.
Read moreDoes atrial flutter have QRS?
The ECG shows atrial flutter with narrow QRS complexes signifying recruitment of the ventricles using the His-Purkinje conduction system. The flutter waves are seen as regular continuous undulations in multiple ECG leads at a rate of ≈290 cycles per minute.
