How I analyze the ECG
• Rate (6 x number of QRS complexes)
• Rhythm How does P wave look in LII (+ve) = Sinus Rhythm
• P waves Morphology? Leads II (2.5-small blocks) and V1 (mainly +ve)
• PR Normal (130 – 200ms), short (<130ms) or long (>200ms)• PR segment (Pericarditis)
• QRS V1, V6 (duration / morphology – LBBB or RBBB? / Q waves)
• Axis Quick method (aVL & LII ) or detailed
• ST Normal; elevated or depressed
• T waves Usually same direction as the QRS
• QT interval Long QT syndromes (V5-6, LII)

Bradycardia
Pattern Recognition & Management
• If slow and regular Complete Heart Block
Mobitz II
Sinus Bradycardia
• If slow, irregular & ‘groups-of-QRS’Mobitz I
• If you see 3 P waves unconducted = High AV block
