The rhythm is irregular with premature ventricular contractions. The rate is 80/min. The P waves are upright and are paired with a QRS complex. The PR interval is prolonged. Two unifocal PVCs are present. A compensatory pause follows each PVC. PR: .24 sec, QRS: .08 sec, QT: .40 sec.
2.
The rhythm is irregular with a rate of 40/min. No P waves are present. The QRS complexes are wide and poorly organized. PR: ---, QRS: .44 sec, QT: .88 sec
3.
The rhythm is irregular. No P waves are seen but there are flutter waves present. There are two 3 beat runs of ventricular tachycardia present. The complexes appear monomorphic. PR: ---, QRS: .10 sec, QT: .32 sec.
4.
The rhythm is regular with a rate of 56/min. Flutter waves are present between each QRS complex in a 3:1 ratio. No ectopic beats are present. PR: ---, QRS: .08 sec, QT: ---
5.
The rhythm is regular with a rate of 115/min. There are negative P waves which precede each QRS complex. No ectopic beats are present. PR: .12 sec, QRS: .08 sec, QT: .32 sec.

| Normal sinus rhythm with unifocal PVCs |
The rhythm is irregular with premature ventricular contractions. The rate is 80/min. The P waves are upright and are paired with a QRS complex. The PR interval is prolonged. Two unifocal PVCs are present. A compensatory pause follows each PVC. PR: .24 sec, QRS: .08 sec, QT: .40 sec.

| Atrial flutter with a pair of three beat runs of ventricular tachycardia |
The rhythm is irregular. No P waves are seen but there are flutter waves present. There are two 3 beat runs of ventricular tachycardia present. The complexes appear monomorphic. PR: ---, QRS: .10 sec, QT: .32 sec.
