From the Guidelines
IntraVentricular (IV) flutter is not a recognized medical term in the context of cardiac arrhythmias, and it is possible that it may be confused with atrial flutter, which is a type of supraventricular tachycardia characterized by rapid, regular oscillations of the atria. The provided evidence does not mention IntraVentricular (IV) flutter, but rather discusses various types of supraventricular tachycardias, including atrial flutter, which is a well-defined condition 1.
Key Points
- Atrial flutter is a type of supraventricular tachycardia characterized by rapid, regular oscillations of the atria.
- It is typically associated with a saw-tooth pattern of regular atrial activation on the ECG, particularly visible in leads II, III, and aVF.
- The management of atrial flutter focuses on treating the underlying cardiac condition, as well as controlling the heart rate and preventing thromboembolic events.
- The provided evidence does not support the existence of IntraVentricular (IV) flutter as a distinct medical condition.
Recommendations
Based on the available evidence, it is recommended to focus on the management of atrial flutter and other supraventricular tachycardias, rather than pursuing a diagnosis of IntraVentricular (IV) flutter. This approach prioritizes the treatment of recognized cardiac conditions, and may help to improve patient outcomes and reduce morbidity and mortality. In cases where a patient presents with symptoms suggestive of a cardiac arrhythmia, a comprehensive cardiac evaluation, including ECG and echocardiography, should be performed to determine the underlying cause of the symptoms 1.
