Practice EKG Rhythm Strips 113
Identify the following rhythms.
2.
3.
5.
The rhythm is irregular with a rate of 90/min. The P waves are upright and precede each QRS complex. After the 2nd complex, there are PACs every other beat. The P waves of the PACs have a different shape, morphology, than the sinus P waves. PR: .12 sec, QRS: .08 sec, QT: .36 sec.
2.
The rhythm is irregular due to the PJC. The rate is 70/min. The P waves are associated with a QRS complex. The P wave of the 5th complex is negative. PR: .16 sec, QRS: .08 sec, QT: .32 sec.
3.
The rhythm is regular with a rate of 80/min. The P waves are upright. An early beat follows the 3rd complex. The P wave of this atrial ectopic beat is hidden within the T wave of the preceding complex. There is 1mm ST depression present. PR: .12 sec, QRS: .08 sec, QT: .40 sec.
5.
The rhythm is irregular due to the PVC. The rate is 80/min. P waves are present, upright and associated with a QRS complex. A single PVC is present. The S wave is very slurred and irregular. PR: .22 sec. QRS: .16 sec, QT: .40 sec.

| Normal sinus rhythm with bigeminal PACs |
The rhythm is irregular with a rate of 90/min. The P waves are upright and precede each QRS complex. After the 2nd complex, there are PACs every other beat. The P waves of the PACs have a different shape, morphology, than the sinus P waves. PR: .12 sec, QRS: .08 sec, QT: .36 sec.

| Normal sinus rhythm with unifocal PVCs |
The rhythm is irregular due to the PVCs. The rate is 100/min. P waves are upright and uniform. Unifocal PVCs are present. PR: .12 sec, QRS: 08 sec, QT: .24 sec.
