lation -Rhythm originates in the ventricles.

4. Asystole -Absence of electrical activity.
5. 1st Degree AV -The PR interval is prolonged (> 200 msec).
Block -Benign and asymptomatic. No treatment required.

Block Type I -PR interval increases until a QRS complex is dropped.
-P waves without accompanying QRS complexes.
