54 results about "Cardiac monitors" patented technology

A cardiac monitor is provided that monitors the condition of the heart of a cardiac patient and generates signals indicating one of several conditions, such as supraventricular tachycardia, ventricular tachycardia and ventricular fibrillation. In order to generate these signals, the ECG from the patient is analyzed to determine a cardiac interval and heart rate, as well as a waveform factor and a waveform factor irregularity. The waveform factor is derived from the average of the ECG amplitudes during a cardiac interval and the peak value of the ECG during the same interval. Preferably, a running average is calculated over several intervals. This waveform factor is then used to detect shockable ventricular arrhythmia. The waveform factor irregularity is indicative of the variability of the waveform factor and is used to differentiate between ventricular tachycardia and ventricular defibrillation.

An implantable medical device (IMD), such as a cardiac monitor and/or pulse generator is implanted during a procedure where a biologic is introduced into a targeted area of the heart. The IMD monitors cardiac performance to determine the efficacy of the biologic. Based on the achieved efficacy, the IMD will either take no action, provide device based therapy, and/or ablate the tissue to destroy the biologic and its effects if the biologic proves unsuccessful.

The wearable heartbeat measuring device is accomplished by wearing a wrist-watch-like heart monitor device on the wrist. The heart monitor is worn on the top of the wrist with a strap around the wrist. The strap has an inflexible extending portion that extends from the heart monitor at a predetermined angle and a predetermined width with respect to the wrist so that a predetermined space is maintained between the top portion of the wrist and the strap for promoting the transfer efficiency of the pulsation force that is initially experienced at a part of the strap at the bottom of the wrist. The strap also has a flexible portion. A predetermined angle and a predetermined width of the extended portion also facilitate the flexible portion to form a flat area where the wrist contacts the strap. In the prefer embodiments, the width of the strap exceeds the width of the wrist when it is worn.

A bioelectric interface for monitoring, detection and transmission of detected ECG data is provided comprising a sensory system for detecting bio-physiological measurements utilizing spatially resolved potential profiles obtained from a localized cluster of sub-electrodes to form constituent sets of miniature sensor arrays. Using only a single macro-electrode, two or more sets of sub-electrode arrays are used to measure bipolar spatial gradients obtained from measured cardiac potentials. The sets of sub-electrodes containing the clusters are optimized to attain measurable gradients of diagnostic value. A minimax procedure allows bio-potential sensory acquisition through a bi-directional digital steering process, which essentially comprises monitoring, detection, selection, grouping, recording and transmission of ECG waveform characteristic data.

A heart monitor is disclosed. The monitor computes ST segment deviations and stores the results in heart rate based histograms. Periodically, the monitor analyzes the histogram data to determine a median value of ST deviation. Subsequently, beats are excluded from the computation of the time series if their ST deviations both varies too far from the long term median value and varies too far from the then current time series value.

For cardiac rhythm management, a combination of cardiac pacing and a noninvasive heart monitoring is proposed for the determination of a set of programmable pacing parameters hemodynamically beneficial to the patient. The apparatus incorporates a cardiac pacemaker and a thoracic electrical bioimpedance (TEB) heart monitor. This combination allows the creation of a closed-loop system that obtains pacing parameter settings providing hemodynamically beneficial pacing therapy to the patient as determined by measuring and recording of stroke volume (SV), cardiac output (CO), and other indices of ventricular performance by the heart monitor during an optimization cycle automatically employing different permutations of values of pacing parameters such as atrioventricular delays, inter-atrial delay, inter-ventricular delay, or heart rate, that are sequentially programmed to the pacemaker. The hemodynamically beneficial permutation of pacing parameter values is determined from all recordings and programmed to the pacemaker for permanent or temporary pacing therapy.
