The rhythm is regular and the rate is 57/min. There are biphasic P waves present. The first deflection is negative followed by a positive upstroke. No ectopic beats are present. There is some slurring of the R wave which almost gives it a delta-looking appearance. PR: .12 sec, QRS: .10 sec, QT: .44 sec.
2.
The rhythm is irregular due to the PVCs. The rate is 90/min. There are upright P waves that precede a QRS complex. Two unifocal PVCs are present. The PVCs are followed by a compensatory pause. The PVCs have a buried P wave in the down slope of the S wave. If you measure the P-P interval you will see that the P-P intervals on the blocked P waves are the same as the sinus beats. PR: .18 sec, QRS: .08 sec, QT: .38 sec.
3.
The rhythm is regular with a rate of 44/min. There are uniform P waves present that precede each QRS complex. No ectopic beats are noted. PR: .16 sec. QRS: .10 sec. QT: .48 sec.
4.
The rhythm is irregular due to the frequent PVCs. The rate is 100/min. The P waves are upright and precede the QRS complex. There are a pair of multifocal PVCs occurring every 3rd beat. PR: .12 sec, QRS: .10 sec, QRS: .40 sec.
5.
The rate is irregular due to the PVCs. The rate is 60/min. The P waves are upright and precede the QRS complex. The are unifocal PVCs that happen every other beat, bigeminy. The PVCs are followed by a short compensatory pause. PR: .12 sec, QRS: .10 sec, QT: .44 sec.

| Sinus bradycardia with biphasic P waves |
The rhythm is regular and the rate is 57/min. There are biphasic P waves present. The first deflection is negative followed by a positive upstroke. No ectopic beats are present. There is some slurring of the R wave which almost gives it a delta-looking appearance. PR: .12 sec, QRS: .10 sec, QT: .44 sec.

| Normal sinus rhythm with unifocal PVCs |
The rhythm is irregular due to the PVCs. The rate is 90/min. There are upright P waves that precede a QRS complex. Two unifocal PVCs are present. The PVCs are followed by a compensatory pause. The PVCs have a buried P wave in the down slope of the S wave. If you measure the P-P interval you will see that the P-P intervals on the blocked P waves are the same as the sinus beats. PR: .18 sec, QRS: .08 sec, QT: .38 sec.

| Bigeminal couplets |
The rhythm is irregular due to the frequent PVCs. The rate is 100/min. The P waves are upright and precede the QRS complex. There are a pair of multifocal PVCs occurring every 3rd beat. PR: .12 sec, QRS: .10 sec, QRS: .40 sec.
