Content developed by MIMS Learning http://www.mimslearning.co.uk/

INTRODUCTION

In this module, the second of a series on ECG interpretation, we discuss key steps including practicalities of ECG acquisition, lead placement, determining cardiac axis, calculating heart rate and assessing rhythm. Key learning points include causes of axis deviation, methods of calculating rate and categories of heart rhythm. This module includes a 2-question test of ECG interpretation.
