What is an ECG or an EKG? a. What does each wave of the ECG represent? b. Explain what is occurring in the heart at each wave. Which wave on the ECG trace marks the onset of ventricular systole and why? What does the QRS complex of an ECG represent?
The electrical activity in the heart can be recorded by an electrocardiogram (ECG or EKG).Answer and Explanation: The P wave in an ECG is a recording of the depolarization of the right atrium and left atrium. Depolarization refers to when the muscles of these......
The waves or deflections shown on the ECG are named for the letters P, Q, R, S and T. R waves are the first upward deflection within a series known as the QRS complex. As part of the QRS complex, an R wave is an important indicator of cardiac health. Cardiologists and other ...
What is your morning routine? We’ve asked this question time and again; here we share every answer, collected together into one, convenient location.
244K An electrocardiogram (ECG) records the flow of electrical current on three distinct waves. Explore the purpose of an ECG, the three wave types, and the purpose of each wave on an ECG. Related to this QuestionWhat is an ECG? What does a normal ECG indicate? What does the EKG mea...
EKG: An EKG is a graph showing the activity of the heart. It shows the depolarization and repolarization of the heart chambers, making it possible to diagnose issues with the heart's function. Answer and Explanation:1 The QRS complex is the most noticeable wave on an EKG tracing. In a no...
