Question

Analysis of the EKG can reveal:

Answer 1

Answer:

The best answer to the question: Analysis of the EKG can reveal:____, would be: A: All of the above.

Explanation:

An EKG, or ECG, is a diagnostic testing process that seeks to measure the correct functioning of the heart´s electrical system through the detection of the electrical currents generated by the specialized neural cells, as they lead the myocardial cells to depolarize. This is done by placing a series of electrodes on the surface of the skin, on the chest wall. These electrodes will detect the flow of energy as the cells depolarize and repolarize, and this generates the electrical current that is shown on the EKG as a tracing. Because the electrical current is generated thanks to the action potentials that are initiated on the myocardial cells, and these action potentials depend on cation (sodium, potassium and calcium) levels, and gradients, and the way that the current flows also depends on the structure of the heart muscles and connecting neural tissue, is why the best option is A. Also, the position inside the chest cavity, of the heart, will show on the tracings of an EKG, allowing a physician to know how the heart is positioned inside the chest.
