Rapid Review of basic ECG

1. Rapid Review of EKG Arranged by Hosam Ghanem ,MD Damascuss university , Mars , 2006 Before you go through this breaf review ,please have a look to Alagha algorythm of arrhythmias. During this review try to diagnose before you see it written

2. Normal sinus rhythm

3. Sinus bradycardia

4. Sinus tachycardia

5. Wandering pacemaker

6. Atrial flutter

7. Atrial fibrillation

8. Junctional rhythm

9. Premature ventricular contraction Time interval between normal R peaks is a multiple of R-R intervals

10. Wide ventricular complexes Rate> 120/min Ventricular tachycardia

11. Ventricular fibrillation

12. Pacer rhythm Wide ventricular complexes preceded by pacemaker spike Rate is the pacer rhythm

13. P-wave precedes each QRS-complex but PR-interval is > 0.2 s First-degree atrioventricular block

14. Intermittently skipped ventricular beat Second-degree atrioventricular block

15. P-P interval normal and constant, QRS complexes normal, rate constant, 20 - 55 /min Third-degree atrioventricular block

16. RIGHT BUNDLE-BRANCH BLOCK QRS duration greater than 0.12 s Wide S wave in leads I, V 5 and V 6

17. LEFT BUNDLE-BRANCH BLOCK QRS duration greater than 0.12 s Wide S wave in leads V 1 and V 2 , wide R wave in V 5 and V 6

18. LEFT ATRIAL HYPERTROPHY Wide, notched P wave in lead II Diphasic P wave in V 1

19. RIGHT ATRIAL HYPERTROPHY Tall, peaked P wave in leads I and II

20. RIGHT VENTRICULAR HYPERTROPHY Large R wave in leads V 1 and V 3 Large S wave in leads V 6 and V 6

21. LEFT VENTRICULAR HYPERTROPHY Large S wave in leads V 1 and V 2 Large R wave in leads V 6 and V 6
