摘要： Methods and system are provided for monitoring a patients venous blood oxygen saturation (SvO2). At least one signal indicative of electrical activity of a patient's heart is obtained. Such a signal can be, e.g., an IEGM or ECG signal. In specific embodiments, such a signal(s) can be obtained from implanted electrodes, and thus, embodiments of the present invention can be implemented by an implantable system. Additionally, there are measurements of at least one metric of cardiac cycles represented in the at least one signal indicative of electrical activity of the patient's heart, where the metric changes with changes in SvO2. Examples of such metric include T-wave metrics and PR intervals. SvO2, and changes therein, are monitored based on the measured metric(s).

摘要： Implantable systems, and methods for use therewith, enable the monitoring of a patient's electromechanical delay (EMD) and arterial blood pressure. Paced cardiac events are caused by delivering sufficient pacing stimulation to cause capture. A cardiogenic impedance (CI) signal, indicative of cardiac contractile activity in response to the pacing stimulation being delivered, is obtained. One or more predetermined features of the CI signal are detected, and a value indicative of the patient's EMD is determined by determining a time between a delivered pacing stimulation and at least one of the detected one or more features of the CI signal. The value indicative of EMD can be used to more accurately determine metrics indicative of pulse arrival time (PAT), which can be used to estimate arterial blood pressure.

摘要： Embodiments of the present invention are directed to implantable systems, and methods for use therewith, that monitor and modify a patient's arterial blood pressure without requiring an intravascular pressure transducer. In accordance with an embodiment, for each of a plurality of periods of time, there is a determination one or more metrics indicative of pulse arrival time (PAT), each of which are indicative of how long it takes for the left ventricle to generate a pressure pulsation that travels from the patient's aorta to a location remote from the patient's aorta. Based on the one or more metrics indicative of PAT, the patient's arterial blood pressure is estimated. Changes in the arterial blood pressure are monitored over time. Additionally, the patient's arterial blood pressure can be modified by initiating and/or adjusting pacing and/or other therapy based on the estimates of the patient's arterial blood pressure and/or monitored changes therein.

摘要： In specific embodiments, a method for estimating a patient's central arterial blood pressure (CBP) for use with an implantable system, comprises (a) using an implanted sensor at a first site to obtain a first signal indicative of changes in arterial blood volume at the first site, the first site being along one or more peripheral arterial structures of the patient, (b) using an implanted sensor at a second site to obtain a second signal indicative of changes in arterial blood volume at the second site, the second site being a distance from the first site downstream along an arterial path of the peripheral arterial structure of the patient, and (c) using implanted electrodes to obtain a signal indicative of electrical activity of the patient's heart. The method further comprises (d) determining a time t1 from a predetermined feature of the signal indicative of electrical activity to a predetermined feature of one of the first and second signals, the time t1 being a first pulse arrival time (PAT1) indicative of how long it takes a pulse wave to travel from the patient's aorta to one of the first and second sites, (e) determining a time t2 from a predetermined feature of the signal indicative of electrical activity to a predetermined feature of the other of the first and second signals, the time t2 being a second pulse arrival time (PAT2) indicative of how long it takes a pulse wave to travel from the patient's aorta to the other of the first and second sites, and (f) estimating the patient's central arterial blood pressure (CBP) based on the first pulse arrival time (PAT1) and the second pulse arrival time (PAT2).
