EKG Rhythm Strips 54
Identify the following rhythms
2.
3.
4.
5.
The rhythm is regular with a ventricular rate of 71/min. The P waves are negative and follow the QRS complex. No ectopic beats are seen. The ST segment is down slopping. PR: ---, QRS: .08 sec, QT: .44 sec.
2.
The rhythm is irregular. The rate is 48/min. No P waves are seen but some fibrillatory activity is seen between the QRS complexes. No ectopic beats are seen. PR: ---, QRS: .12 sec, QT: .40 sec.
3.
Artifact from a loose lead. The electrical activity is too coarse to be ventricular fibrillation.
4.
The rhythm is irregular due to the PVCs. The rate is 78/min. The P waves are upright and precede the QRS complexes. Multifocal PVCs are present. PR: .20 sec, QRS: .12 sec, QT: .44 sec.
5.
The rhythm is irregular because of the alternating demand and sinus beats. The rate is 78/min. The P waves are not seen. There appears to be some atrial fibrillation between the QRS complexes. No ectopic beats are seen. Ventricular paced beats are seen every other beat. The 3rd and the 13th complexes may represent some kind of fusion beat. PR: ---, QRS: .10 sec, QT: .40 sec.

| Demand ventricular paced |
The rhythm is irregular because of the alternating demand and sinus beats. The rate is 78/min. The P waves are not seen. There appears to be some atrial fibrillation between the QRS complexes. No ectopic beats are seen. Ventricular paced beats are seen every other beat. The 3rd and the 13th complexes may represent some kind of fusion beat. PR: ---, QRS: .10 sec, QT: .40 sec.
