The rhythm is irregular with multiple ectopic beats. The ventricular rate is 96/min. (Count number of R waves in this 10 strip and multiple by 6). The P waves are upright and have a corresponding QRS complex. The are multiple ectopic beats present, 2nd 6th, 10th, 12th, 13th and 15th complexes. There appears to be a P wave associated with the 1st and 2nd ectopic beats these are actually be fusion beats. The 12th and 13th complexes are PVCs that form a multifocal couplet. The 15th complex is a PVC that is followed by a compensatory pause and an atrial escape beat. PR: .20 sec, QRS; .10 sec, QT: .40 sec.
2.
The rhythm is irregular with multiple PVCs. The P waves are positive and are associated with a QRS complex. There are unifocal PVCs present. A compensatory pause follows each PVC. PR: .16 sec, QRS: .08 sec, QT: .38 sec.
3.
The rhythm is regular with a rate of 166/min. The P waves are upright and are paired with a QRS complex. The P waves are fused with the T wave of the previous complex. No ectopic beats are noted. PR: .10, QRS: .06 sec, QT: .28 sec.
4.
The rhythm is irregular. The heart rate is 90/min. The P waves are upright and precede the QRS complexes. There are multifocal PVC present in a trigeminal pattern. A compensatory pause follows each PVC. The ST segment is slopping downward and there is inversion of the T wave. PR: .20 sec, QRS: .08 sec, QT: .44 sec.
5.
The rhythm is irregular. The rate is 20/min. There are no P waves present. The QRS complex is wide and bizarre looking. The rhythm changes to asystole after the 2nd complex.

| Atrial tachycardia |
The rhythm is regular with a rate of 166/min. The P waves are upright and are paired with a QRS complex. The P waves are fused with the T wave of the previous complex. No ectopic beats are noted. PR: .10, QRS: .06 sec, QT: .28 sec.

| NSR with ventricular trigemeny |
The rhythm is irregular. The heart rate is 90/min. The P waves are upright and precede the QRS complexes. There are multifocal PVC present in a trigeminal pattern. A compensatory pause follows each PVC. The ST segment is slopping downward and there is inversion of the T wave. PR: .20 sec, QRS: .08 sec, QT: .44 sec.

| Agonal rhythm changing to aystole |
The rhythm is irregular. The rate is 20/min. There are no P waves present. The QRS complex is wide and bizarre looking. The rhythm changes to asystole after the 2nd complex.
