Heart sound monitoring of pulmonary hypertension |
| 摘要 |
A medical device system and method that includes receiving an A2 heart sound signal from a first external acoustic sensor, receiving a P2 heart sound signal from a second external acoustic sensor, determining at least one A2 heart sound signal parameter from the A2 heart sound signal, determining at least one P2 heart sound signal parameter from the P2 heart sound signal, and based on the at least one P2 heart sound signal parameter, estimating pulmonary arterial pressure. |

1. A method comprising:
receiving an A2 heart sound signal from a first external acoustic sensor; receiving a P2 heart sound signal from a second external acoustic sensor; determining at least one A2 heart sound signal parameter from the A2 heart sound signal; determining at least one P2 heart sound signal parameter from the P2 heart sound signal; based on the at least one P2 heart sound signal parameter, estimating pulmonary arterial pressure; receiving a pulmonary pressure signal from a pressure catheter; and calibrating the at least one P2 heart sound signal parameter with the pulmonary pressure signal. |
