Abstract

Electrocardiography is regularly used in the investigation of heart problems, but the correct interpretation and understanding of an ECG readout can be difficult for students to learn and teachers to teach. An aide memoire that breaks down many of the parameters in ECG evaluation into ‘3s and 5s’ can aid in remembering the details.

Key Points

  • The ECG offers much valuable information for the assessment of heart problems and patient care.
  • Interpretation of the ECG requires a systematic approach.
  • Reading the ECG using a simple aide memoire that breaks down important components into ‘3s and 5s’ can help the novice reader gain confidence.
