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
Normal sinus rhythm
Sinus bradycardia
Sinus tachycardia
Wandering pacemaker
Atrial flutter
Atrial fibrillation
Junctional rhythm
Premature ventricular contraction
Time interval between normal R peaks is a multiple of R-R intervals
Wide ventricular complexesRate> 120/min
Ventricular tachycardia
Ventricular fibrillation
Pacer rhythm
Wide ventricular complexes preceded by pacemaker spikeRate is the pacer rhythm
P-wave precedes each QRS-complex but PR-interval is > 0.2 s
First-degree atrioventricular block
Intermittently skipped ventricular beat
Second-degree atrioventricular block
P-P interval normal and constant,QRS complexes normal, rate constant, 20 - 55 /min
Third-degree atrioventricular block
RIGHT BUNDLE-BRANCH BLOCKQRS duration greater than 0.12 sWide S wave in leads I, V5 and V6
LEFT BUNDLE-BRANCH BLOCKQRS duration greater than 0.12 sWide S wave in leads V1 and V2, wide R wave in V5 and V6
LEFT ATRIAL HYPERTROPHYWide, notched P wave in lead IIDiphasic P wave in V1
RIGHT ATRIAL HYPERTROPHY
Tall, peaked P wave in leads I and II
RIGHT VENTRICULAR HYPERTROPHYLarge R wave in leads V1 and V3
Large S wave in leads V6 and V6
LEFT VENTRICULAR HYPERTROPHYLarge S wave in leads V1 and V2
Large R wave in leads V6 and V6
