Diagnosis – Atrial Flutter Sinus P waves are absent . The classic “sawtooth” pattern occurs, as the reentrant circuit around the tricuspid valve is large, resulting in high-amplitude P waves.10 Nis 2017
Read moreWhy is there no P wave in atrial fibrillation?
Because the atrial rate is so fast, and the action potentials produced are of such low amplitude , P waves will not be seen on the ECG in patients with atrial fibrillation.

Read moreWhat is the most common presentation of atrial flutter?
The common form of typical atrial flutter has saw-tooth flutter waves , best seen in leads II, III, and aVF, with atrial rates of 240-340 bpm. The ventricular response may be regular or irregular. Variable AV conduction can also be seen (commonly present with 2:1 or 3:1 AV conduction).
Read moreWhat is the hallmark of atrial fibrillation?
The hallmark of atrial fibrillation is absence of P-waves and an irregularly irregular (i.e totally irregular) ventricular rate . The baseline (isoelectric line between QRS complexes) is characterized by either fibrillatory waves (f-waves) or just minute oscillations.

The most common symptom: a quivering or fluttering heartbeat
Read moreWhat is the hallmark characteristic of atrial flutter?
Atrial flutter is an abnormal cardiac rhythm characterized by rapid, regular atrial depolarizations at a characteristic rate of approximately 300 beats/min and a regular ventricular rate of about 150 beats/min in patients not taking atrioventricular (AV) nodal blockers.9 Mar 2021
