Sinus arrhythmia and a PAC. The rhythm irregular even with the PAC. The rate is between 46 -54. There is an upright P wave before each QRS complex. PRI: .20 sec. QRS: .08 QT: .52. The P wave of the PAC (4th complex) is buried in the T wave of the preceding complex. You will notice that it differs in shape and height from the other T waves of the other sinus beats.
2.
Atrial bigeminy. The rhythm is regular except for the atrial ectopy. The rate is 80. There is an upright P wave for each QRS complex. PRI: .12 sec. QRS: .08 sec QT: .36 There are PACs every other beat which gives this a bigeminal pattern. The P waves of the PACs are smaller than the native, sinus, P waves.
3.
Atrial fibrillation with multifocal PVCs. The rhythm is irregular. There are fibrillatory waves but there are no readily identifiable P waves associated with each QRS complex. The rate is controlled and about 60 (by counting the QRS complexes in a six second strip) There is no PR interval. QRS: .06 QT: .42. The 2nd and 7th complexes are multifocal PVCs. This simply means that they arise from different foci within the ventricle.
4.
Atrial fibrillation with slow ventricular response and a couplet of PVCs. The rhythm is irregular. The rate is in the 50s. There are fibrillatory waves present but no P waves associated with each QRS complex. PRI: none QRS: .06 QT .40 The 4th and 5th complexes form a couplet or two PVCs that occur one after the other. The PVCs have different a different morphology so they are called multiform or multifocal PVCs. The term slow ventricular response refers to the ventricular rate. If the ventricular rate is < 60 then it is termed a slow response, 60-100 controlled rate, > 100 rapid ventricular response.

Sinus rhythm with unifocal PVCs. The rhythm is regular except for the PVCs. The rate is 100. There are upright P waves before each sinus QRS complex. PRI; .20 sec QRS: .12 sec QT: .28. There are unifocal PVCs occurring every 5th beat, pentageminy.
7.
1st degree AV block with unifocal PVCs. The rhythm is regular except for the PVCs. The rate is 78. There are upright P waves before each sinus QRS complex. PRI; .24 sec QRS: .08 sec QT: .40. There are unifocal PVCs occurring every 6th beat, hexageminy perhaps.

Sinus bradycardia with a PAC. The rhythm regular except for the PAC. The rate is 50. There is an upright P wave before each QRS complex. PRI: .20 sec. QRS: .08 QT: .52. The P wave of the PAC (2nd complex) is buried in the T wave of the preceding complex. You will notice that it differs in shape and height from the other T waves of the other sinus beats.
