I don't see a P wave after the 1st pacer spike and the pacer spikes occur just prior to the QRS complexes. The rhythm is regular. The rate is 71/min. Very small upright P waves are noted before each QRS complex. No ectopic beats are present. A biventricular pacer spike preceeds each QRS complex.
2.
The rhythm is irregular. The rate is 140/min. There are no P waves present, fibrillatory waves only. No ectopic beats are noted. PR: ---, QRS: .06 sec, QT: .38 sec.
3.
The rhythm is regular. The calculated rate is 93/min. The P waves are upright and precede each QRS complex. No ectopic beats are identified. PR. 12 sec, QRS: .12 sec, QT: .32 sec.

The underlying rhythm is regular. The calculated rate is 75/min. The P waves are upright and precede each QRS complex. There is a single early complex that has an atrial ectopic focus, the 3rd beat. This is followed by a short pause then the a rhythm of sinus origin resumes. The T waves are inverted. PR: .12 sec, QRS: .08, QT: .40 sec.

The rhythm is regular. The calculated rate is 75/min. There are upright P waves before each QRS complex. There are small atrial pacer spikes before each P wave. There are also small ventricular pacer spikes before each QRS complex. The T waves are upright and appear tall. PR: .12, QRS: .12 sec, QT: .48 sec.
