The electrocardiogram is a recording of the electrical activity of the heart as it undergoes excitation (depolarization) and recovery (polarization) to initiate each beat of the heart. This electrical activity is represented by a tracing showing the various phases of the activity above or below ...
This activity is recorded using an electrocardiographic machine connected to the patient with four electric leads (labelled 1, 11 ,111, AVR, AVL, AVF) on the ankles and wrists and six on the front of the chest over the heart area (labelled V1-6). The normal pattern of the ECG allows...

An echocardiogram is a different kind of test for your heart. It's an ultrasound test, which means it uses sound waves to create pictures of your heart as it beats. But with an EKG, a computer translates the electrical signals from your heart into a pattern of wavy lines that your docto...
The heart is a two-stage electrical pump. The upper chambers of the heart (atrium) collect blood from the body and the lower chambers (ventricle) pump blood to the body. There is an electrical conducting system in the heart that helps coordinate each heart beat (cardiac cycle) of collecting...
≥92% of participants will be able to recognize life-threatening ECG rhythms and understand the importance of ECG monitoring. Objectives After this course, the participant will be able to: Describe normal cardiac anatomy and normal electrical conduction through the heart. Identify and relate ECG wa...
aDoctors routinely use electrocardiographs to make electrocardiogrames(EKGs) or records, of the electrical activity of the heart, and electroencephalographs to make electroencephalogrames(EEGs) of the brain\'s electrical activity. 医生定期地使用electrocardiographs创造electrocardiogrames( EKGs) 或纪录,心...
Refer back to the figure below as you read about the different blocks:Right bundle branch block (RBBB)RBBB may be a normal variant – especially if the pattern is present but with a normal QRS duration. Otherwise it may indicate problems with the right side of the heart. In RBBB you ...
Learn how medical professionals can detect a heart attack using an EKG. Discover how an EKG works, the clinical manifestations of a heart attack, how to interpret an EKG reading, and what signs indicate or confirm a heart attack. Heart Attack: Definition Let's say that you're stuck in ...
Abbreviated ECG or EKG, an electrocardiogram provides vital information about the electrical activity of your heart. It is a key element in the detection of various cardiac complications. Learn more about the test's requirements, its reading, and how to interpret certain abnormalities with a home-...
