Measurement of cardiac cycle length and pressure metrics from pulmonary arterial pressure Title: Measurement of cardiac cycle length and pressure metrics from pulmonary arterial pressure.Abstract: A method and apparatus for monitoring a cardiovascular pressure signal in a medical device that includes comparing the sensed pressure signal to a first pressure threshold, identifying a first sense greater than the first pressure threshold, determining a metric of the pressure signal in response to the identified first sense, comparing the sensed pressure signal to a second pressure threshold not equal to the first pressure threshold in response to the identified first sense, identifying a second sense, subsequent to the first sense, greater than the second pressure threshold, identifying a third sense, subsequent to the first sense, greater than the first pressure threshold, and determining a cycle length corresponding to electrical activity of a heart in response to one of the first sense and the third sense or the second sense and the third sense. ...
USPTO Applicaton #: #20120277599 - Class: $ApplicationNatlClass (USPTO) - Inventors: Saul E. Greenhut
The Patent Description & Claims data below is from USPTO Patent Application 20120277599, Measurement of cardiac cycle length and pressure metrics from pulmonary arterial pressure.
Cross-reference is hereby made to the commonly-assigned related U.S. application No. —————— (Attorney Docket Number P0041928.01), entitled “MEASUREMENT OF CARDIAC CYCLE LENGTH AND PRESSURE METRICS FROM PULMONARY ARTERIAL PRESSURE”, filed concurrently herewith and incorporated herein by reference in it's entirety.
In general, this disclosure describes techniques for cardiovascular monitoring. The cardiovascular monitoring techniques may include determining a cardiac cycle length and/or cardiovascular pressure metrics such as systolic pressure and diastolic pressure from a pressure signal detected by a pressure sensor implanted within the pulmonary artery of a patient. In some cases, a derivative of the pressure signal may be used to determine the cardiac cycle length and/or the cardiac pressure metrics. Additionally, second or higher order derivatives may be taken in order to identify other morphological fiducial points on the pressure waveform that contribute to measurements with clinical diagnostic value. Averaging and cross correlation or mathematical transform techniques may also be used for this purpose. Using the techniques of this disclosure, an implantable medical device may deliver drug therapy or therapeutic electrical stimulation, or acquire diagnostic information, based on the determined cardiac cycle length and/or various pressure metrics.
In some examples, IMD 16 delivers pacing pulses via bipolar combinations of electrodes 40, 42, 44, 46, 48 and 50 to produce depolarization of cardiac tissue of heart 12. In some examples, IMD 16 delivers pacing pulses via any of electrodes 40, 42, 44, 46, 48 and 50 in combination with housing electrode 58 in a unipolar configuration. For example, electrodes 40, 42, and/or 58 may be used to deliver RV pacing to heart 12. Additionally or alternatively, electrodes 44, 46, and/or 58 may be used to deliver LV pacing to heart 12, and electrodes 48, 50 and/or 58 may be used to deliver RA pacing to heart 12.
Furthermore, IMD 16 may deliver defibrillation pulses to heart 12 via any combination of elongated electrodes 62, 64, 66 and 67, and housing electrode 58. Electrodes 58, 62, 64, 66 may also be used to deliver cardioversion pulses to heart 12. Electrodes 62, 64, 66 and 67 may be fabricated from any suitable electrically conductive material, such as, but not limited to, platinum, platinum alloy or other materials known to be usable in implantable defibrillation electrodes.
Pressure sensor 92 may be implanted within pulmonary artery 100, for example, using a delivery catheter. For example, a physician may deliver pressure sensor(s) 92 via a delivery catheter, transvenously through either the internal jugular or femoral veins. The delivery catheter then extends through superior vena cava 176, right atrioventricular valve 164, right ventricle 152, and pulmonary valve 166 into pulmonary artery 100. In other examples, pressure sensor 92 may be implanted after a physician has opened the patient\'s chest by cutting through the sternum.
