Answers


1.

Atrial fibrillation with slow ventricular response

The rhythm is irregular with a rate of 50/min.   Fibrillatory waves are present between the QRS complexes.  The 5th complex is a PVC.  PR:  ---,  QRS:  .08 sec,  QT:  .36 sec.


2.

Ventricular paced

The rhythm is regular and the rate is 60/min.   No P waves are noted.  No ectopic beats are present.  A ventricular pacer spike precedes each QRS complex.  PR:   ---,  QRS:  .16 sec,  QT:  .44 sec.


3.

Sinus arrhythmia

The rhythm is irregular with a rate of 80/min.  The R-R interval between the 3rd and 4th complexes is 1.0 sec and the R-R interval between the 7th and 8th complexes is .64 sec   There are uniform, upright P waves before each QRS complex.  No ectopic beats are noted.  PR;  .12 sec,  QRS:  .08 sec,  QT:  .36 sec


4.

Atrial flutter with unifocal PVCs

The rhythm is irregular with a rate of 80/min.  P waves are absent and flutter waves are seen between the QRS complexes.  There are trigeminal PVCs present.  PR:  ---,  QRS:  .08 sec,  QT:  .38 sec.


5.

NSR with run of ventricular tachycardia

The rhythm is irregular and is dominated by frequent and recurring runs of ventricular tachycardia.
