The rhythm is irregular with a rate of 80/min. Flutter waves are seen between the QRS complexes. The ratio of flutter waves to QRS complexes varies. No ectopic beats are identified. PR: ---, QRS: .16 sec, QT: .40 sec
2.
The rhythm is irregular with a ventricular rate of 48/min. P waves are absent but some fibrillation is noted between the QRS complexes. No ectopic beats are seen. PR: ---, QRS: .12 sec, QT: .48 sec.
3.
The rhythm is regular with a rate of 60/min. Atrial pacer spikes precede the very small P waves. No ectopic beats are noted. PR: .20 sec, QRS: .08 sec, QT: .44 sec.
4.
The rhythm is regular. The rate is 32/min. The P waves are absent. No ectopic beats are noted. The QRS complex is narrow. PR: ---, QRs: .08 sec, QT: .52 sec.
5.
The rhythm is regular. The ventricular rate is 65/min. The P waves are upright, uniform, and are paired with a QRS complex. No ectopic beats are noted. There is a down slopping ST segment with an inverted T wave in lead II and a corresponding 3mm ST elevation in the V1 lead. PR: .12 sec, QRS: .16 sec, QT: .44 sec.

| Atrial flutter with variable ventricular response |
The rhythm is irregular with a rate of 80/min. Flutter waves are seen between the QRS complexes. The ratio of flutter waves to QRS complexes varies. No ectopic beats are identified. PR: ---, QRS: .16 sec, QT: .40 sec

| Atrial fibrillation with slow ventricular response |
The rhythm is irregular with a ventricular rate of 48/min. P waves are absent but some fibrillation is noted between the QRS complexes. No ectopic beats are seen. PR: ---, QRS: .12 sec, QT: .48 sec.

| Atrial paced |
The rhythm is regular with a rate of 60/min. Atrial pacer spikes precede the very small P waves. No ectopic beats are noted. PR: .20 sec, QRS: .08 sec, QT: .44 sec.

| Junctional rhythm |
The rhythm is regular. The rate is 32/min. The P waves are absent. No ectopic beats are noted. The QRS complex is narrow. PR: ---, QRs: .08 sec, QT: .52 sec.

| Normal sinus rhythm with ST elevation in the V1 lead |
The rhythm is regular. The ventricular rate is 65/min. The P waves are upright, uniform, and are paired with a QRS complex. No ectopic beats are noted. There is a down slopping ST segment with an inverted T wave in lead II and a corresponding 3mm ST elevation in the V1 lead. PR: .12 sec, QRS: .16 sec, QT: .44 sec.
