Revision

• Reminder of the standard 12-lead ECG…
• Reminder of our systematic approach to any ECG…
• How the ECG waveform matches to the deflections…
• A reminder of how we calculate rate…
• Outline the normal ranges for PR interval, QRS duration and QT interval…
• Here’s some questions to ask when identifying rhythm…
• Remind yourself of how each lead looks at the heart…
• Reminder of the normal QRS axis of the heart…
• Let’s remind ourselves of right axis deviation…
• And also, let’s remind ourselves of left axis deviation again…
• Reminder of the normal P/QRS/T morphology…

New Content

• An outline of normal conduction…
• What can happen to cause abnormal conduction?
• What will we see in a right bundle branch block?
• What do we see in a left bundle branch block?
• Here’s an algorithm to assess tachycardias…
• Now, here’s an algorithm to assess brachycardias…
