ECGs have a logic to them, and it is a fun exercise to figure out stuff from ECG.

You will be asked about popular and common patterns, not obscure findings in ECG.

Once you identify the ECG, the question may have a second part – how do you manage the arrhythmia, or what could have caused this.

For that you have to know about

• Mechanisms of common arrhythmias
• Syndromes like WPW, Torsades de Pointes
• Types and mechanisms of Heart Block
• Common drugs used in each type of arrhythmia & Heart Block
