When talking about energy what is a wave?

A wave is the energy emission itself.

Explanation:

When talking about waves many think automatically about ocean waves or surface waves within large bodies of water. However, on a deeper scale of understanding, energy itself is in a form of wave. Which is measured by frequency, altitude, and wavelength. These measurements determine a waves energy levels. It is important to remember that there are variety of energies or waves (such as microwaves, x-rays, ultraviolet, infrared, visible light, etc..), and each wave has a specific measurement in terms of frequency altitude, and wavelength.

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
