Answers


1.
Accelerated junctional rhythm

The rhythm is regular with a heart rate of 71/min.   The P waves are absent.   No ectopic beats are noted.   The QRS complex is narrow.   PR:  ---,  QRS:  .08 sec,  QT:  .40 sec.


2.
Multifocal atrial tachycardia


The rhythm is irregular with ventricular rate of 150/min.    P waves are upright but are not uniform in appearance.   There is also some variability in the PR interval.   No ectopic beats are noted.  PR:  .16 sec,  QRS:  .08 sec,  QT:  .32 sec.

3.
Atrial flutter













The rhythm is regular with a rate of 71/min.   There flutter waves seen between the QRS complexes.  No ectopic beats are noted.  PR:  ---,  QRS:  .08 sec,  QT:  undetermined.


4.
Atrial paced













The rhythm is regular with a heart rate of 68/min.   The P waves are preceded by an atrial pacing stimulus.   No ectopic beats are seen.   PR:  .20 sec,  QRS:  .10 sec,  QT:  .40 sec.


5.
Normal sinus rhythm with ventricular bigeminy













The rhythm is irregular.   The rate is 90/min.   The P waves are uniform, positive, and paired with a QRS complex.   There are unifocal PVCs every other beat.  A compensatory pause follows each PVC.   PR:  .12 sec,  QRS:  .08 sec,  QT:  .28 sec.

Answers


1.
2nd degree heart block type II

The rhythm is irregular with a ventricular rate of 20/min and an atrial rate of  75/min.   The P waves are upright but not all of them are paired with a QRS complex.  No ectopic beats are noted.  The QRS complex is wide.   PR:  .20 sec,  QRS:  .12 sec,  QT:  .64


2.
2nd degree heart block type I
The rhythm is irregular with a heart rate of 50/min.   The P waves are upright and uniform.    There is a nonconducted P wave after the 2nd complex.    The PR interval progressively lengthens over successive beats.   PR:  .20/.24/.32sec,  QRS:  .08 sec,  QT:  .40 sec


3.
3rd degree heart block












The rhythm is regular with a ventricular rate of 30/min and an atrial rate of 100/min.   The P waves are upright and uniform but they are not associated with a QRS complex.   The QRS complex is wide suggesting a ventricular escape origin.  PR:  ---,  QRS:  .16 sec,  QT:  undetermined


4.
1st degree heart block
The rhythm is regular with a rate of 79/min.   The P waves are wide, upright, and associated with a QRS complex.   Wide P waves are associated with left atrial enlargement.  The PR interval is prolonged.   There are unifocal PVCs every fourth beat.   PR:  .28 sec,  QRS:  .12 sec,  QT:  .44 sec.


5.
2nd degree heart block type II













The rhythm is regular and the ventricular rate of 38/min and an atrial rate of  107/min.  The P waves are uniform and upright but not all of them have a corresponding QRS complex.   No ectopic beats are noted.   PR:  . 18 sec,  QRS:  .12 sec,  QT:  .56 sec.
