Reading ECG Strips

Reading ECG Training

Our Reading ECG tutorial and guides provide basic training and a fast look-up guide for many types of ECG. The ECG strip drills and quizzes allow you to practice electrocardiogram interpretation.

What is an ECG?

An ECG (electrocardiogram) is a recording of electrical activity in the heart. An ECG machine captures these electrical signals across multiple heart beats and prints an strip.

How To Read ECGs

To briefly summarize the features used in reading ECGs; 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 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 Guide

Our reading ECG guide provides information about many types of arrhythmias. For each ECG arrhythmia 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.

Reading ECG Training

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