Atrial flutter is a type of abnormal heart rhythm that occurs when the upper chambers of the heart, called the atria, beat too quickly. In this video, we'll discuss the causes, symptoms, and how to analyze atrial flutter.
Atrial flutter can be caused by a variety of factors, including underlying heart disease, such as hypertension or coronary artery disease, and other medical conditions, such as thyroid disease or pulmonary embolism. Certain medications, such as stimulants or some antidepressants, can also trigger atrial flutter. In some cases, atrial flutter can occur without an identifiable cause.
The symptoms of atrial flutter can vary depending on the severity of the condition. Some people may not experience any symptoms at all, while others may experience palpitations, chest discomfort, shortness of breath, or fatigue. In some cases, atrial flutter can lead to more serious complications, such as stroke or heart failure.
Atrial flutter is a type of cardiac arrhythmia characterized by a rapid, regular atrial rhythm, usually 250-350 bpm, and a slower and usually regular ventricular rhythm with a ventricular rate of 75-150 bpm. The pathophysiology of atrial flutter involves abnormal electrical activity in the atria, which can be triggered by various factors.
In contrast with normal sinus rhythm, in atrial flutter, there is a re-entry circuit that forms within the atria, which allows electrical impulses to travel in a circular pattern rather than in a straight line. This circuit is usually located in the right atrium, near the tricuspid valve, but can also occur in the left atrium. As a result, the atria beat rapidly and regularly, but the ventricles may beat at a slower and irregular rate, depending on how many of the atrial impulses are transmitted through the AV node.
The treatment for atrial flutter depends on the underlying cause and the severity of the condition. In some cases, atrial flutter may not require treatment, while in other cases, medication or a procedure may be necessary. Medications such as beta-blockers or calcium channel blockers can be used to slow down the heart rate and control the rhythm. Electrical cardioversion may be necessary to restore the heart's normal rhythm. In more severe cases, a procedure called catheter ablation may be performed, which involves using a catheter to destroy the small area of the heart tissue that is causing the abnormal rhythm.
The symptoms of atrial flutter can vary and can be serious if left untreated. If you experience symptoms of atrial flutter, it's important to see your doctor for an accurate diagnosis and appropriate treatment. Remember, early detection and treatment can help prevent serious complications and improve your overall heart health.
