Intervention: RESPeRATE Breathing Trial
Description: RESPeRATE Breathing will test whether a controlled breathing relaxation technique using an FDA-approved paced breathing device, RESPeRATE, helps with chest pain and shortness of breath and will test to see if this form of biofeedback or relaxation technique helps with heart rate variability during mental stress.
