really out of breath. I have SVT should i make an App?

Apparently you have known supraventricular tachycardia. But that doesn't explain why you are out of breath and have jaw pain. You don't specify where you have "pressure on my chest."
You don't give your age or gender, but your symptoms do indicate that you should promptly see your physician about them. Jaw pain and chest pressure and shortness of breath can all be related to a heart problem.
