According to one implementation, a medical device includes a display, a blood pressure sensor for sensing an arterial blood pressure of a patient and for generating a blood pressure signal, an analog-to-digital converter (ADC) for receiving the blood pressure signal and for converting the blood pressure signal to blood pressure data in digital form, and a hardware processor for executing an aortic stenosis diagnostic software code. The hardware processor executes the aortic stenosis diagnostic software code to receive the blood pressure data from the ADC, and to identify parameters indicative of aortic stenosis in the patient, based on the blood pressure data. The hardware processor further executes the aortic stenosis diagnostic software code to classify the severity of aortic stenosis in the patient based on an exponential function of the parameters.
