ECG Interpretation: Conduction disease

Part three of a 5 part lecture series on ECG/EKG Interpretation on conduction disease with Dr Theo Sklavos and cardiologist A/Prof William Wang. This lecture series is aimed primarily at medical/nursing/paramedicine students and junior trainees, but will hopefully be useful as a refresher course for those with previous experience.

Conduction disease

• Identify AV nodal block, bundle branch and fascicular blocks.
• Identify escape rhythms and their origin.
