The criteria is the same as Wandering Atrial Pacemaker with the only difference being the heart rate exceeds 100 bpm. These changes in the locus of stimulation within the atria affect the morphology of the P waves. Remember, you must observe at least three differen...
As a byproduct, the “atrial” rate (P-waves) for atrial flutters beats between 250 to 350 beats per minute and is typically regular and constant. EKG Category 1: Rhythm regularity Atrial flutter can present with a regular or irregular ventricular rhythm. Because the rhythm can be regular ...

Repolarization is only electrical, and during that, the heart is at rest. Three major waves of electric signals appear on the ECG. Each one shows a different part of the heartbeat. The first wave is called the P wave. It records the electrical activity of the atria. The second and ...
In healthy people, a tracing will consist of a specific pattern that falls within an expected range. This not only includes the up-and-down waves (called the P wave, QRS complex, ST segment, and T wave) but also the spaces in between them (called a PR interval and QT interval).4 ...
The P wave represents the depolarization of the atria and is associated with their contraction. The QRS wave complex consists of three waves. The first negative deflection is the Q wave and is followed by a positive deflection called the R wave. The complex ends with a negative deflection know...
Q waves that persist for more than one day may result from other causes than necrosis. Profound and prolonged ischemia can cause myocardial stunning with reversible functional, metabolic, ultrastructura, and electeophysiologic abnormalities. Thus, transient Q waves may be the electrocardiographic counter...
6. P-wave and PR interval Can you see a p-wave? If the rhythm is atrial fibrillation, atrial flutter or a junctional tachycardia you may not be able to. At this point you can also assess whether each p wave is associated with a QRS complex. P-waves not in association with QRS compl...
