ECG Tracing

ECG Tracings

We provide several ways to practice ECG tracing interpretation:

  • Practice Drills
  • ECG Quiz
  • ECG Guide
  • ECG Basic Training Lessons
Each of these training methods is summarized below.

How Electrocardiograms Work - ECG Tracings

To briefly summarize the components of a normal ECG, it consist of components which indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U.

P wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles.

The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction.

The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles.

T wave is normally a modest upwards waveform representing ventricular repolarization.

ECG Practice Tracings and Drills

Using multiple choice questions and answers, users are asked to identify arrhythmia tracings. Digital calipers are available to assist in analyzing each ECG practice tracing. Feedback is provided after each response.

ECG Tracing Reference Guide

Our ECG tracings guide provides information about many types of arrhythmias. For each practice ECG strips we provide multiple electrocardiogram tracings. Electrocardiogram analysis is provided using a concise summary of the ECG's key features. Tracing features can be measured using our digital calipers.

ECG Lessons - Introduction

The focus of this introductory ECG course is to provide a tutorial about the main features of ECGs along with a method for analyzing ECGs. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of intervals and segments and the evaluation of other relevant waves.
ECG practice exercises serve to reinforce the lesson content.
