The rhythm is regular with a rate of 75/min. Both atrial and biventricular pacer spikes are seen before the P waves and the QRS complexes. PR: .20 sec, QRS: .16 sec, QT: .48 sec.
2.
The rhythm is regular. The ventricular rate is 65/min. An atrial pacing stimulus is seen before each P wave. No ectopic beats are seen. PR: .20 sec, QRS: .08 sec, QT: .48 sec.
3.
The rhythm is regular. The heart rate is 60/min. Atrial pacer spikes are seen before the P waves. No ectopic beats are seen. The ST segment is isoelectric but the T wave is inverted. PR: .20 sec, QRS: .08 sec, QT: .44 sec.
4.
The rhythm is regular with a ventricular rate of 68/min. There are flutter/fibrillatory waves seen between the QRS complexes. A ventricular pacing stimulus is seen before each QRS complex. No ectopic beats are seen. PR: ---, QRS: ,16 sec. QT: .56 sec.
5.
The rhythm is regular with a rate of 75/min. The P waves are wide, split, and precede the QRS complex. Wide P waves suggest left atrial enlargement. No ectopic beats are seen. PR: .16 sec, QRS: . 12 sec, QT: .40 sec.
