Practice EKG Rhythm Strips 116
Identify the following rhythms.
2.
3.
4.
5.
The rhythm is regular with a rate of 65/min. The P waves are upright and precede the QRS complexes. The PR interval is prolonged. No ectopic beats are noted. PR: .32 sec, QRS: .08 sec, QT: .40 sec
2.
The rhythm is irregular. No identifiable P wave. There appears to be some fibrillatory activity between some of the QRS complexes, complex 5 and 13. Most likely this atrial fibrillation with with a wide QRS complex. Until proven otherwise, treat at VT.
3.
The rhythm is regular and the rate is 51/min. There are upright P waves associated with the QRS complex. No ectopic beats are present. PR: .14 sec, QRS: .08 sec, QT: .60 sec.
4.
The rhythm is regular with a rate of 68/min. Small atrial paced P waves are present. The PR interval is prolonged. No ectopic beats are noted. PR: .28 sec, QRS: .10 sec, QT: .44 sec,
5.
The rhythm is irregular due to the PVCs. The rate is 90/min. The P waves correspond to a QRS complex. Unifocal PVCs occur every 4th beat. PR: .24 sec, QRS: .08 sec, QT: .40 sec
