This is because the P waves (flutter waves) in atrial flutter occur at about 250-350 per minute (usually around 300) . At this rate, it can appear that there is a P wave in front of each QRS and a T wave after each QRS. This causes the misdiagnosis of sinus tachycardia or SVT.
Read moreWhat do atrial arrhythmias include?
In general, signs and symptoms of arrhythmias may include: A fluttering in the chest . A racing heartbeat (tachycardia) A slow heartbeat (bradycardia)
Read moreWhat are the ECG characteristics of atrial fibrillation?
Findings from 12-lead electrocardiography (ECG) usually confirm the diagnosis of AF and include the following: Typically irregular ventricular rate (QRS complexes) Absence of discrete P waves, replaced by irregular, chaotic F waves. Aberrantly conducted beats after long-short R-R cycles (ie, Ashman phenomenon)

Read moreWhat is considered 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.
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).
