What is an ECG? An ECG is a paper or digital recording of the electrical signals in the heart. It is also called an electrocardiogram or an EKG. The ECG is used to determine heart rate, heart rhythm and other information regarding the heart's condition. ECGs are used to help diagnose heart arrhythmias, heart attacks, pacemaker function and heart failure.
Our ECG Tutorial and Reference Guides provide basic lessons for ECG analysis as well as a quick reference guide for over 35 categories of cardiac conditions. The arrhythmia drills and quizzes allow you to practice ECG analysis.
Using multiple choice questions and answers, users are asked to identify arrhythmia tracings. Digital calipers are available to assist in analyzing each ECG practice strip. Feedback is provided after each response.
Our ECG tutorial guide provides information about many types of arrhythmias. For each ECG arrhythmia we provide multiple electrocardiogram tracings. ECG analysis is provided with a concise summary of the ECG's key features. Tracing features can be measured using our digital calipers.
The focus of this introductory ECG tutorial 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 EKG intervals and segments and the evaluation of other relevant waves. ECG practice exercises serve to reinforce the lesson content.
