Answer to Question 1

nonconducted or blocked

Answer to Question 2

Rhythm Regular.
Rate 100 to 250 beats/min.
P waves One P wave precedes each QRS complex in lead II; P waves differ in shape from sinus P waves; an isoelectric baseline is usually present between P waves; if the atrial rhythm originates in the low portion of the atrium, P waves will be negative in lead II. With rapid rates, it is difficult to distinguish P waves from T waves.
PR interval May be shorter or longer than normal.
QRS duration 0.11 seconds or less unless abnormally conducted.
