1- Inverted P waves (F waves) in II, III and AVF.
2- saw-tooth pattern between QRS complexes in II,III and AVF.
3- Atrial rate is 250-400 and regular but ventricular rate depends on AV node and between 60-150 and typically regular.
4- QRS is not wide
5- T waves not identifiable.
On the ECG the diagnostics for AFib will be; and atrial rate of 400-600 beats per minute, with a variable ventricular rate, the ventricular rate will be irregularly irregular (no repeatable pattern whatsoever), there won't be any P Waves, just fibrillation waves thus there won't be a measurable PR interval, however the QRS will still be less than .10-.12 seconds.
They're he same thing. Atrial flutter is more of a slang term, and is sometimes found in patients with atrial tachycardia. Basically, atrial fibrillation is a disorder, and atrial flutter is a symptom
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
Atrial flutter-- Rapid, inefficient contraction of the upper chamber of the heart.
Atrial Flutter is characterized by rapid depolarization of a single atrial focus at a rate of 250-350 BMP
Atrial Flutter. You may be thinking of atrial fibrillation, though.
ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
Ventricular fibrillation, since this pumps blood to the rest of the body.
The P wave.
