Chapter 3: Atrial Fibrillation and Atrial Flutter Flashcards
ECG analysis is especially useful in?
Detecting and diagnosing cardiac arrhythmias which are abnormal patterns of cardiac activity.
What is the most common Arrhythmia?
Atrial fibrillation (A-Fib)
In Atrial Fibrillation there is a complete absence of?
SA node stimulus that would result in a P wave.
As a result of Atrial Fibrillation there are no?
Distinct P waves.
QRS complexes are present but?
Are irregularly spaced.
In Atrail Fibrillation the atria are?
Fibrillating or quivering and the arterial and coronary circulations lose at least 30% of their normal supply.
Atrial flutter is an abnormality of?
Conduction within the Atria.
As with Atrial Fibrillation, the ventricles work normally?
Yes.
The symptoms of Atrial Flutter tend to be lesss severe than?
Atrial Fibrillation and there is less rick of clot formation.
Atrail Flutter tends to spontaneously revert back to?
Sinus rhythm in some cases.
Are flutter waves more defined than fibrillary waves?
Yes.
P waves tend to resemble the?
Teeth of a saw.
QRS complexes occur at a set ratio to P waves for example?
2:1, 3:1, or 4:1.
