1. A method comprising:
- analyzing a heart sound signal of a patient for a time interval from a first external sensor to detect a pulmonary hypertension signature;
analyzing a lung sound signal of the patient for the time interval from a second external sensor to detect a heart failure-signature;
when one of the heart failure signature or the pulmonary hypertension signature is detected, then determine whether the other of the heart failure signature or the pulmonary hypertension signature is detected;
delivering a first therapy to the patient via a medical device in response to detecting the pulmonary hypertension signature but not the heart failure signature, the first therapy having a first set of therapy parameters;
delivering a second therapy to the patient via the medical device in response to detecting the heart failure signature but not the pulmonary hypertension signature, the second therapy having a second set of therapy parameters; and
delivering a third therapy to the patient via the medical device in response to detecting both the pulmonary hypertension signature based on the analyzed heart sound signal and the heart failure signature based on the analyzed lung sound signal, the third therapy having a third set of therapy parameters.
