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
Is P wave absent in atrial flutter?
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. Distinguishing between clockwise and counterclockwise atrial flutter was described previously.
Why P wave is absent in atrial flutter?
Absence of P Waves
A lack of visible P waves preceding QRS complexes suggests a lack of sinus beats; this may occur with sinus dysfunction or in the presence of fibrillation or flutter waves. The P wave may also be hidden within the QRS complex.
