Answer to Question 1

Rhythm Ventricular regular; atrial regular (Ps plot through); no relationship between the atrial and ventricular rhythms (i.e., AV dissociation is present).
Rate The ventricular rate is determined by the origin of the escape rhythm; the atrial rate is greater than (and independent of) the ventricular rate; ventricular rate is determined by the origin of the escape rhythm.
P waves Normal in size and shape; some P waves are not followed by a QRS complex (i.e., more Ps than QRSs).
PR interval None. The atria and the ventricles beat independently of each other; therefore there is no true PR interval.
QRS duration Narrow or wide, depending on the location of the escape pacemaker and the condition of the intraventricular conduction system.

Answer to Question 2

T
The point where the QRS complex and the ST segment meet is called the ST junction or the J point. The ST segment is considered elevated if the segment is deviated above the baseline and is considered depressed if the segment deviates below it.
