During contractions, the abdomen becomes rigid. For some women, the pain stays in the lower back area. Contractions feel a little different for everyone. At the beginning of labor, most contractions last from 60 - 90 seconds and occur every 15 to 20 minutes.
Implantable medical device for treating cardiac mechanical dysfunction by electrical stimulation
InactiveUS6738667B2Increase contractilityEasy to relaxCatheterHeart stimulatorsCardiac cycleHeart chamber
An implantable stimulator and monitor measures a group of heart failure parameters indicative of the state of heart failure employing EGM signals, measures of blood pressure including absolute pressure P, developed pressure (DP=systolic P-diastolic P), and / or dP / dt, and measures of heart chamber volume (V) over one or more cardiac cycles. These parameters include: (1) relaxation or contraction time constant tau (.tau.); (2) mechanical restitution (MR), i.e., the mechanical response of a heart chamber to premature stimuli applied to the heart chamber; (3) recirculation fraction (RF), i.e., the rate of decay of PESP effects over a series of heart cycles; and (4) end systolic elastance (E.sub.ES), i.e., the ratios of end systolic blood pressure P to volume V. These heart failure parameters are determined periodically regardless of patient posture and activity level. The physician can determine whether a particular therapy is appropriate, prescribe the therapy for a period of time while again accumulating the stored patient data for a later review and assessment to determine whether the applied therapy is beneficial or not, thereby enabling periodic changes in therapy, if appropriate. Drug therapies and electrical stimulation therapies, including PESP stimulation, and pacing therapies including single chamber, dual chamber and multi-chamber (bi-atrial and / or bi-ventricular) pacing can be delivered. In patient's prone to malignant tachyarrhythmias, the assessment of heart failure state can be taken into account in setting parameters of detection or classification of tachyarrhythmias and the therapies that are delivered.

System and method for infrasonic cardiac monitoring
ActiveUS20160361041A1With balanceHigh and good performanceBlood flow measurement devicesHealth-index calculationVentricular contractionCardiac monitoring
Cardiac Output (CO) has traditionally been difficult, dangerous, and expensive to obtain. Surrogate measures such as pulse rate and blood pressure have therefore been used to permit an estimate of CO. MEMS technology, evolutionary computation, and time-frequency signal analysis techniques provide a technology to non-invasively estimate CO, based on precordial (chest wall) motions. The technology detects a ventricular contraction time point, and stroke volume, from chest wall motion measurements. As CO is the product of heart rate and stroke volume, these algorithms permit continuous, beat to beat CO assessment. Nontraditional Wavelet analysis can be used to extract features from chest acceleration. A learning tool is preferable to define the packets which best correlate to contraction time and stroke volume.

Systems and methods for determining systolic time intervals
InactiveUS20080167566A1Efficiently and accurately diagnoseUltrasonic/sonic/infrasonic diagnosticsElectrocardiographyCardiac cycleData profiling
A method and system for determining systolic time intervals, by analysis of radio frequency (RF) scatter patterns in conjunction with Electrocardiogram (ECG) data, is provided. An RF emitter is placed on the cardiac patient. The emitter includes two or more transmitting antennas which emit RF radiation into the cardiac patient, resulting in an RF scatter pattern. An RF sensor receives the scattered RF signals. The RF emitted from the antennas will differ spatially with regard to the RF sensor, causing the RF scatter patterns to differ from one another. A signal processor analyzes these differences to identify inhomogeneous structures, and to identify aortic valve motion, including aortic valve opening and closure. An electrocardiogram identifies the onset of the cardiac cycle. Systolic intervals are determined using the onset of the cardiac cycle and the aortic valve motion. Cardiac contractility also is determined by correlation to systolic intervals. An acoustic sensor is used to verify the aortic valve closure.

Systolic timing intervals are measured in response to delivering pacing energy to a pacing site of a patient's heart. An estimate of a patient's acute response to cardiac resynchronization therapy (CRT) for the pacing site is determined using the measured systolic timing intervals. The estimate is compared to a threshold. The threshold preferably distinguishes between acute responsiveness and non-responsiveness to CRT for a patient population. An indication of acute responsiveness to CRT for the pacing site may be produced in response to the comparison.
