Electrocardiography is a medical test that detects heart abnormalities by measuring the electrical activity generated by the heart as it contracts. Coursera's electrocardiography catalogue teaches you the fundamental principles of this vital diagnostic tool. You'll learn how to interpret basic and complex electrocardiograms, understand the electrical and physiological aspects of the heart, and recognize common cardiac conditions such as arrhythmias, heart blocks, and myocardial infarctions. This knowledge will equip you to contribute effectively in a clinical setting, whether as a healthcare professional or a researcher in cardiology.
