Abstract: Methods, systems, and apparatuses are described for cardia treatment and analysis. A computing device may cause a head mounted visual display worn by a patient to output visual imagery. The visual imager is configured to affect a psychological perception of the patient. The computing device may cause exercise equipment in use by the patient to affect a physical exercise performed by the patient. The computing device may measure, via one or more sensors, a cardiac exertion of the patient. The computing device may determine, based on the cardiac exertion of the patient, that the patient has not reached a maximum cardiac exertion. The computing device may adjust one or more of the visual imagery or the physical exercise. The adjustment may cause the patient to reach the maximum cardiac exertion.
