Idioventricular Rhythm. The Rhythm is regular but there are no P waves present. The QRS complex is wide and regular so the orgin of the rhythm is within the ventricles. If this were a junctional rhythm, then the QRS complex would be narrower because the origin of the impulse is the AV junction which uses the regular ventricular conduction system.
2.
Sinus Arrhythmia. The rhythm is irregular with variability in the R-R interval. There is one upright P wave for each QRS and the PR interval is < 0.20 sec. By definition, sinus arrhythmia is present when there is a P-P difference of over .12 sec. among various beats.
3.
Atrial Fibrillation with slow ventricular response. The rhythm is irregular with a wide variability in the R-R interval. There are no identifiable P waves, just a fibrillatory waveform. The QRS complex is wide so it might be easy to confuse this with an idioventricular rhythm. But with an idioventricular rhythm the underlying rhythm is regular and there are no P waves. In this strip the rhythm is both irregular and has fibrillatory waves present.
4.
Ventricular Paced Rhythm. The rhythm is 100% ventricular paced at a rate of 65.
5.
Bradycardia with 1st degree AV block. The rhythm is regular. There is one upright P wave for each QRS complex and the PR interval is .24 seconds. The rate is 42 so this falls within the bradycardic range making this rhythm bradycardia with 1st degree AV block.

Your EKG stripes and reviews are very helpful-
