Answers
1. a. Asystole. Asystole with a functioning single chamber pacemaker.
2. b. NSR with ventricular bigeminy. The rhythm is irregular because of the PVCs. The heart rate is 90/min. The P waves look the same and are paired with a QRS complex. The QRS complexes are narrow. Unifocal PVCs are seen in a bigeminal pattern. PR: .12 QRS: .08 sec, QT: .36 sec. Interpretation: NSR with ventricular bigeminy or bigeminal PVCs
3. a. Accelerated idioventricular rhythm. This rhythm is regular. The heart rate is 50/min. No P waves are seen. The QRS complex is wide so this screams that it is a ventricular rhythm. No ectopic beats are seen. PR: ---, QRS: .16 sec, QT: .44 sec. Interpretation: Accelerated Idioventricular rhythm.
4. d. Sinus rhythm with trigeminal PVCs. The rhythm is irregular due to the PVCs. The rate is 68/min. The P waves are uniform, upright, and are paired with a QRS complex. Three consecutive PVCs follow the 2nd complex. This is followed by a short compensatory pause then sinus rhythm resumes. PR: .16 sec, QRS: .08 sec, QT: .40 sec. Interpretation: Sinus rhythm with triplet of PVCs
5. a. Sinus bradycardia with a pause. Yikers! This looks serious. The rhythm is irregular due to the pause. The heart rate is 30/min. The P waves are associated with a QRS complex. There is a 2.2 sec pause following the 1st beat. No ectopic beats are seen. PR: .16 sec, QRS: .10 sec, QT: .44 sec.
