B) fusion. C) flutter. D) fascicle. 23) How many different wave configurations in the same lead indicate a wandering atrial pacemaker (WAP)? A) Two B) Three C) Four D) None 24) Identify the following rhythm: امر امه من ام الحمام A) Atrial fibrillation B) Atrial flutter C) Wandering atrial pacemaker D) Multifocal atrial tachycardia 25) Identify the following rhythm: www.hmongol A) Atrial fibrillation

Answer 1

Ans 21: D) Premature atrial complexes (PAC)

Premature atrial complexes (PAC) is a most frequent arrhythmia associated with atrial fibrillation. Premature atrial complexes (PAC) dysrhythmia may show defective P waves in ECG.

Ans 22: A) focus

A cardiac cell or group of cells that produce an ectopic beat is known as a focus. The ectopic beat is produced due to the abnormal electrical conductivity in the heart.

Ans 23: B) Three

The Three different wave configurations in the same lead indicate a wandering atrial pacemaker (WAP). When the natural cardiac pacemaker site shifts between the SA node, the atria, and AV node or between Atria or AV node, the arrhythmia occurs id called Wandering atrial pacemaker (WAP).

Ans 24:  B) Atrial flutter

usually, atrial flutter is identified by observing a sudden-onset of abnormal heart rhythm on an electrocardiogram (ECG) with a fast heart rate.
