Abstract
This document discusses, among other things, systems and methods to estimate an arterial diastolic pressure of a patient using ventricular pressure information of a heart of the patient and heart sound information of the heart of the patient, such as a timing of at least one of a first heart sound (S1) or a second heat sound (S2), in certain examples, adjusted by a respective correction factor.
Claims20
A system, comprising:
- a pressure signal input circuit configured to receive ventricular pressure information of a heart of a patient;
- a heart sound signal input circuit configured to receive heart sound information of the heart of the patient;
- and
- an arterial diastolic pressure circuit configured to estimate an arterial diastolic pressure of the patient using the ventricular pressure information and the heart sound information of the heart.

A method, comprising:
- receiving ventricular pressure information of a heart of a patient using a pressure signal input circuit;
- receiving heart sound information of the heart of the patient using a heart sound signal input circuit;
- and
- estimating, using an arterial diastolic pressure circuit, an arterial diastolic pressure of the patient using the ventricular pressure information and the heart sound information of the heart.
1 more element
A system, comprising:
- a pressure sensor configured to sense a ventricular pressure of a patient over a first time interval;
- a heart sound sensor configured to sense a heart sound signal of the patient over the first time interval;
- a heart sound detection circuit configured to detect a timing of at least one of a first heart sound (S1) or a second heart sound (S2) in the first time interval using the heart sound signal;
- and
- an arterial diastolic pressure circuit configured to estimate an arterial diastolic pressure of the patient using the ventricular pressure over the first time interval and the timing of at least one of the S1 or the S2 in the first time interval.
