Basic EKG Interpretation
Our EKG Interpretation tutorial provide basic lessons for EKG analysis as well as a quick reference guide for over 40 types of EKG tracings. The arrhythmia drills and quizzes allow you to practice EKG interpretation.
What is EKG Interpretation?
An electrocardiogram or EKG, is a test that records electrical activity across multiple heart beats and produces an EKG strip that is interpreted by a healthcare professional.
How Electrocardiograms Work - EKG Strips
To briefly summarize the components of a normal EKG tracings, it 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 begins 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 Interpretation Tutor
Use our online ECG 'Workbook' to practice your ECG analysis skills and to learn over 40 different types of ECG tracings. After your analysis is completed, our ECG tutor presents an analysis from an ECG expert.

EKG Interpretation Drills
Using multiple choice questions and answers, users are asked to identify arrhythmia tracings. Digital calipers are available to assist in analyzing each EKG practice strip. Feedback is provided after each response.
Arrhythmia Practice Drills
Our EKG 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 Interpretation Training
The focus of this introductory EKG course is to provide a tutorial about the main features of EKGs along with a method for analyzing EKGs. 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.
EKG practice exercises serve to reinforce the lesson content.
