Question

Interpret the following rhythm:

A) Atrial flutter with variable conduction 
B) Ventricular fibrillation 
C) Atrial fibrillation 
D) Atrial flutter with RVR (rapid ventricular response)

Quizplus · Accepted Answer

Atrial flutter arises from a single irritable focus in the atria.The atrial focus fires at an extremely rapid,regular rate,between 240 and 320 beats per minute.The P waves are called flutter waves and may have a sawtooth appearance.The ventricular response may be regular or irregular based on how many flutter waves are conducted through the AV node.Atrial flutter with RVR occurs when atrial impulses cause a ventricular response greater than 100 beats per minute.Atrial fibrillation arises from multiple ectopic foci in the atria,causing chaotic quivering of the atria and ineffectual atrial contraction.
