WebAtrial Flutter. Atrial flutter is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit in the heart causes the upper chambers (atria) to pump very rapidly. Atrial flutter is important not only because of its symptoms but because it can cause a stroke that may result in permanent disability or death. WebTypes of atrioventricular nodal reentry tachycardia (AVNRT). Atypical AVNRT (fast-slow): 10% of all cases of AVNRT In atypical AVNRT the fast pathway conducts the impulse in antegrade direction while the slow pathway conducts it in the retrograde direction.
