WebJun 13, 2024 · Examples of a single reentrant circuit include atrial flutter and ventricular tachycardia (VT). Under some circumstances, multiple reentrant circuits can develop, resulting in very rapid and chaotic arrhythmias, including atrial fibrillation. ... Atrial flutter — Atrial flutter is an atrial arrhythmia that can be treated with cardioversion ... WebNov 20, 2007 · Atrial flutter is a typical macro-reentrant tachycardia, i.e. the re-entry circuit occupies large areas of the atrium. Most typically, tachycardia rotates in the right atrium counter-clockwise around the tricuspid valve anulus (cavo-tricuspid isthmus – dependent flutter). Atrial rhythm is typically around 300 / min (250-350/min.)

WebAug 8, 2024 · P waves are not detectable. If P waves are detectable, consider sinus tachycardia or atrial fibrillation or flutter as a potential etiology. The remainder of the evaluation is focused on trying to isolate a cause of SVT, for example, electrolyte abnormalities, anemia, or hyperthyroidism. WebShown below is an EKG of an atrial flutter with flutter waves seen best in the inferior leads and in leads V1 to V3. The atrial rate is about 250/min. The QRS is wide (>120ms) and there is a tall R' wave in V1 and a shallow S in V6. The axis of the QRS seems normal. The EKG shows a right bundle branch block .
