![]() What Are ECG Characteristics of Atrial Flutter? In addition, individuals who experience chronic recurring episodes of atrial flutter or have poorly controlled atrial flutter are at risk for heart failure or tachycardia-induced cardiomyopathy. Patients experiencing this arrhythmia are at increased risk for embolism development and stroke. Atrial flutter is generally considered an unstable cardiac rhythm and often transitions into atrial fibrillation.Ītrial flutter typically occurs in individuals with existing health conditions and may occur more frequently in patients with heart failure, chronic obstructive pulmonary disease (COPD), pulmonary hypertension, or heart disease. This rhythm does not usually persist for extended durations of time (in comparison to atrial fibrillation), typically ceasing within minutes, hours, or days. Paroxysmal and acute cases of atrial flutter are common, whereas chronic atrial flutter is rare. Multiple atrial impulses per one ventricular depolarization will occur. This rhythm has a rapid atrial rate with either a variable or fixed ventricular rate. This altered cardiac circuit controls both the heart rate and rhythm. This also leads to rapid cardiac contractions, depolarizations which prevent the heart from filling adequately with blood and result in decreased cardiac output and coronary perfusion. In general, an intrinsic pacemaker impulse originates at the sinoatrial (SA) node within the heart’s right atrium.ĭuring atrial flutter, an abnormal electrical circuit has developed within the atria, causing cardiac electrical impulses to follow a circular path around the right atrium. ![]() Identifying and Treating Atrial Flutter What Is Atrial Flutter?Ītrial flutter is a less common cardiac arrhythmia and can be categorized as a supraventricular tachycardia (SVT), depending on the conduction ratio. ![]()
