An ECG displays cardiac electrical activity. It reveals heart rate, rhythm and cardiac abnormalities. ECG can be used to evaluate heart arrhythmias, pacemakers performance and heart failure.
During each heartbeat, an electrical impulse is transmitted from the atria to the ventricles. This electrical energy causes the heart to contract and thereby pump blood. An ECG machine captures these electrical signals across multiple heart beats and produces an ECG strip that is interpreted by a healthcare professional.
Our online workbook cab be used to practice interpretation skills and to learn over 40 different types of tracings. After your analysis is completed, our ECG tutor presents an analysis from an electrocardiogram expert.
Using multiple choice questions and answers, users try to identify arrhythmia tracings. Digital calipers are available to assist in analyzing each practice strip. Feedback is provided after each response.
Our reference/training guide provides information about many types of arrhythmias. For each arrhythmia we provide multiple electrocardiogram tracings. Analysis is provided using a concise summary of the electrocardiogram's key features. Tracing features can be measured using our digital calipers.
New to our website, a presentation on 12 lead ECG prepared by Dr. Michael Mazzini, M.D., Boston University Medical Center.
The focus of this introductory course is to provide a tutorial about the main features of electrocardiograms along with an analysis method. 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. Practice exercises serve to reinforce the lesson content.
