Reading EKG - Introduction and Lessons

EKG Interpretation

Reading EKG Training

Our Reading EKG Lessons and Reference Guides provide basic training for EKG analysis as well as a quick reference guide for over 40 types of ECG tracings. The arrhythmia drills and quizzes allow you to practice EKG interpretation.

What is an EKG?

An electrocardiogram or EKG, records electrical activity in the heart. An machine records these electrical signals across multiple heart beats and produces an EKG strip that is interpreted by a healthcare professional.

Reading EKGs - How to

To briefly summarize the features used in reading EKGs, they consist of waveform 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 EKG 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.

Reading EKG Drills

Users practice reading EKGs by identifying tracings in a multiple choice questions and answers format. Digital calipers are available to assist in analyzing each EKG practice strip. Feedback is provided after each response.

EKG Guide

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

EKG Training - Introduction

The focus of this introductory EKG course is to provide a tutorial about the main features of EKGs 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.
reading EKG practice exercises serve to reinforce the lesson content.
