ECG of the Week - 1st June 2015

This week's ECG is from a 65 yr old who presented with palpitations for several hours. Past history of paroxysmal atrial fibrillation. We have two tracing to review - the first is a standard 12-lead ECG and the second is a lead I rhythm strip using a Lewis lead configuration but at standard calibration (10mm/mV & 25mm/s).

Things to think about

  • What are the key features on the ECG ?
  • What is a Lewis Lead ?
  • What is the purpose of the Lewis Lead ?
