Atrial Flutter - Causes, Symptom, Cure, Treatment of Atrial Flutter
What is Atrial Flutter?
Atrial flutter is a rhythm disturbance of the atria that results in regular tachycardic ventricular waveforms. Atrial flutter is typically not a stable rhythm, and frequently degenerates to atrial fibrillation . However, it may persist for months to years. Atrial flutter is a form of tachycardia (rapid heart rate).
Causes of Atrial Flutter
Atrial Flutter disease usually occurs because of changes in the atrial muscle that affect its ability to transmit electrical impulses. Atrial flutter commonly occurs in the setting of acute myocardial infarction, after pneumonectomy and after cardiac surgery in adults. It is unusual in children.
Symptoms of Atrial Flutter
- May be asymptomatic, and present with ECG findings of atrial flutter
- Mild symptoms include palpitations,
- irregular heart beat,
- fatigue, dyspnoea,
- chest pain
- Dizziness, light-headedness
- Shortness of breath
- Heart failure
- Thromboembolism with transient ischaemic attacks or stroke
Treatment and Cure of Atrial Flutter
The decision for medical treatment, and the method selected, can be made only after a comprehensive diagnosis. If the patient is unstable, synchronous direct-current cardioversion is commonly the initial treatment of choice. Cardioversion often requires low energies. If the electrical shock results in AF, a second shock at a higher energy level is used to restore normal sinus rhythm (NSR). For most patients with atrial flutter, radiofrequency ablation is the current treatment of choice.
