Interpretation:

1. Sinus tachycardia with 3:1 AV conduction, right bundle branch block (Advanced or high-grade AV block)
2. Agonal Rhythm
3. 2 to 1 AV block
4. Sinus tachycardia with first degree AV block
5. Atrial Flutter with 4:1 AV conduction
6. Atrial fibrillation with slow ventricular response
7. Sinus rhythm with junctional rhythm (isorhythmic AV dissociation)
8. Sinus tachycardia, complete heart block, junctional escape rhythm with RBBB, inferior wall MI
9. Sinus rhythm with non-conducted premature atrial beat
10. Sinus rhythm, second degree AV block type I (typical Wenckebach/Mobitz I) with 5:4 AV conduction
11. Sinus rhythm, complete heart block with junctional escape
12. Atrial fibrillation
13. Sinus rhythm, second degree AV block type I (atypical Wenckebach or Mobitz I)
14. Sinus bradycardia
15. Normal sinus rhythm
16. Sinoatrial block type I
17. Sinus rhythm, second degree AV block type II (Mobitz II), RBBB
18. Sinus arrhythmia
19. Atrial tachycardia
20. Sinus rhythm converting to polymorphic ventricular tachycardia
21.Orthodromic AV reentry tachycardia
22. Multifocal atrial tachycardia, hyperkalemia
23. Supraventricular tachycardia or SVT probably AV nodal reentry tachycardia (AVNRT)
