An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.
The process to measure the electrical signals of the heart can be done by using this machine.
In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.
It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.

Answer:
How rocks change from one type to another and which processes are involved in rock changes.
Explanation:
We know that there are three types of major rocks. Those are: igneous, sedimentary, and metamorphic. The rock cycle describes how the three major rock types convert from one to another.
Changing in rocks happens as a result of natural processes that are taking place all the time. Most of the changes happen very slowly. Rocks that are in the deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them to another rock. Even at the surface, we may not notice the changes in the rocks.
Along with this, a rock cycle describes those process which involves in this rocks transformation process. It represents various environmental factors that are related to the change of the rock from one to another.
