    • A method for estimating pulmonary artery diastolic pressure, for a single heart beat, includes establishing a time window for sampling and storing pressure data points from a right ventricular pressure transducer. The time window may be established according to predetermined parameters and/or according to one or more triggering events. An approximate time at which the pulmonary artery valve opens is determined, either via the sampled pressure data points, or via another form of more direct monitoring, during the time window, in order to estimate the pulmonary artery diastolic pressure. A plurality of sets of N pressure data points may be collected, from the sampled data, and, for each collected set, a weighted sum is calculated. Each weighted sum may be employed to evaluate a quality of the sampled data and/or to estimate the pulmonary artery diastolic pressure, if the more direct monitoring of the pulmonary artery valve is not employed.
    • 用于估计单次心跳的肺动脉舒张压的方法包括建立用于从右心室压力传感器采样和存储压力数据点的时间窗口。 可以根据预定参数和/或根据一个或多个触发事件建立时间窗口。 通过采样的压力数据点或在时间窗口期间通过另一种形式的更直接的监测来确定肺动脉瓣打开的大致时间,以便估计肺动脉舒张压。 可以从采样数据收集多组N个压力数据点,并且对于每个收集的集合,计算加权和。 如果不采用更直接的肺动脉瓣监测,则每个加权和可用于评估采样数据的质量和/或估计肺动脉舒张压。
