The rhythm is regular and the rate is 107/min. The P waves are upright and have a corresponding QRS complex. There is ST depression in lead II and also a 2 mm ST elevation in the V1 lead. No ectopic beats are noted. PR: .16 sec, QRS: .08 sec, QT: .30 sec.
2.
The rhythm is irregular due to the PVCs. The rate is 100/min. The P waves are associated with a QRS complex and are uniform and upright. There are a pair of PVC triplets. PR: .16 sec, QRS: .08 sec, QT: .34 sec.

This is a busy rhythm strip. There was not enough room on it to note all the different complexes. The second complex is a R on T PVC that falls on the later portion of the preceding T wave. The 3rd complex is slightly delayed and there is an upright P wave that has a different morphology from the sinus P waves. This is followed by another pause and escape beat. This is quickly followed by a PAC (5th complex) that has the P wave buried in the preceding T wave. The 6th complex is sinus in origin. The 7th complex is another R on T PVC. The 8th and 9th complexes are sinus beats. The 10th complex is another R on T PVC. The 11th complex is a junctional escape beat that follows the PVC. Notice the retrograde P wave that precedes the QRS complex.
4.
The rhythm is irregular due to the PVCs. The rate is 80/min. The P waves are low upright and precede the QRS complex. There are some unifocal PVCs every 4th beat. PR: .20 sec, QRS: .14 sec, QT: .44 sec.
5.
The rhythm is regular with a heart rate of 150/min. There are no P waves that are readily identifiable. No ectopic beats are noted. PR: ---, QRS: .08, QT: .28 sec.

| Sinus tachycardia with T wave inversion in lead II |
The rhythm is regular and the rate is 107/min. The P waves are upright and have a corresponding QRS complex. There is ST depression in lead II and also a 2 mm ST elevation in the V1 lead. No ectopic beats are noted. PR: .16 sec, QRS: .08 sec, QT: .30 sec.

| Normal sinus rhythm with some triplets of PVCs |
The rhythm is irregular due to the PVCs. The rate is 100/min. The P waves are associated with a QRS complex and are uniform and upright. There are a pair of PVC triplets. PR: .16 sec, QRS: .08 sec, QT: .34 sec.
