Answers


1.
Bigeminy













The rhythm is irregular.   The rate is 80/min.   The P waves are upright and uniform.  There are unifocal PVCs every other beat, bigeminy.  PR:  .20 sec,  QRS:  .12 sec,  QT:  .40 sec.


2.
Hexageminy











The rhythm is irregular.   The rate is 100/min.  There are unifocal PVCs every 6th beat.  Unless this pattern repeats itself regularly, you will probably will not hear of this pattern referred to as hexageminy.  Usually the MD, RNs, Paramedics, and monitor technicians will say NSR with unifocal PVCs.  PR:  .12 sec,  QRS:  .08 sec,  QT:  .32 sec.


3.
Quadrigeminy













The rhythm is regular and the rate is 110/min.   The P waves are upright and precede the QRS complex.  There are PVCs every 4th beats, quadrigeminy.   There is no compensatory pause afterwards.   PR:  .12 sec,  QRS: .10 sec,  QT:  .34 sec.


4.
Pentageminy












The rhythm is irregular.  The rate is 100/min.  The P waves are upright and are associated with a QRS complex.  There are unifocal PVCs every 5th beat.  PR:  .12 sec,  QRS:  .08 sec,  QT:  .30 sec.


5.
Quadrigeminy
















The rate is irregular and the rate is 70/min.  The P waves are upright and precede a QRS complex. There are uniform PVCs every 4th beat, quadrigeminy.   There also appears to be a blocked P wave located in the T wave of the PVCs.   A compensatory pause follows the PVCs. PR:  .20 sec,  QRS:  .08 sec.  QT:  .38 sec.
