摘要:
Methods and systems for assessing pulmonary or systemic vascular resistance in a patient using pressure measurements are disclosed. An illustrative method of measuring pulmonary vascular resistance includes electrically inducing a retrograde pressure pulse within the heart, sensing at least one arterial pressure parameter in response to the retrograde pressure pulse using a pressure sensor located within a pulmonary artery, and computing a value of the pulmonary vascular resistance using the at least one sensed arterial pressure parameter. Data from multiple pulmonary vascular resistance assessments can be taken over an extended period of time within the patient to aid in detecting an underlying cardiac or pulmonary condition such as cardiogenic pulmonary edema.
