A system and method for facilitating a cardiac rhythm disorder diagnosis based on subcutaneous cardiac monitoring data with the aid of a digital computer are provided. Cutaneous action potentials of a patient are recorded as electrocardiogram (EGC) data over a set time period using a subcutaneous insertable cardiac monitor. A set of R-wave peaks is identified within the ECG data and an R-R interval plot is constructed. A difference between recording times of successive pairs of the R-wave peaks in the set is determined. A heart rate associated with each difference is also determined. The pairs of the R-wave peaks and associated heart rate are plotted as the R-R interval plot. A diagnosis of cardiac disorder is facilitated based on patterns of the plotted pairs of the R-wave peaks and the associated heart rates in the R-R interval plot.
Individuals who suffer from certain kinds of medical conditions, particularly conditions that only sporadically exhibit measurable symptoms, can feel helpless in their attempts to secure access to medical care because, at least in part, they are left to the mercy of their condition to present symptoms at the right time to allow diagnosis and treatment. Providing these individuals with ambulatory extended-wear health monitors that record ECG and physiology, preferably available over-the-counter and without health insurance preauthorization, is a first step towards addressing their needs. In addition, these individuals need a way to gain entry into the health care system once a medically-actionable medical condition has been identified. Here, the ECG and physiology is downloaded and evaluated post-monitoring against medical diagnostic criteria. Medical specialists are pre-identified and paired up with key diagnostic findings, such that an individual whose monitoring data indicates a medical concern will be automatically referred and treated.

Individuals who suffer from certain kinds of medical conditions, particularly conditions that only sporadically exhibit measurable symptoms, can feel helpless in their attempts to secure access to medical care because, at least in part, they are left to the mercy of their condition to present symptoms at the right time to allow diagnosis and treatment. Providing these individuals with ambulatory extended-wear health monitors that record ECG and physiology, preferably available over-the-counter and without health insurance preauthorization, is a first step towards addressing their needs. In addition, these individuals need a way to gain entry into the health care system once a medically-actionable medical condition has been identified. Here, the ECG and physiology is downloaded and evaluated post-monitoring against medical diagnostic criteria. Medical specialists are pre-identified and paired up with key diagnostic findings, such that an individual whose monitoring data indicates a medical concern will be automatically referred and treated.

A method for constructing a stress-pliant physiological electrode assembly is provided. An electrode backing is formed from a stretchable woven textile material compatible to contact the skin on at least one surface. A pair of flexile wires is provided to serve as electrode circuit trace and electrode signal pickup. At least one of the flexile wires is sewn into the textile material which provides a stress-pliant malleability. Each of the flexile wires has an electrically-contacting area functioning for electric signal pickup. The electrically-contacting area may be sewn into the woven textile or affixed to the woven textile via conductive adhesives. The stress-pliant physiological electrode assembly is applicable for a wide array of physiological monitors, including ECG monitors, and especially is suitable for long-term wear. The method disclosed is both environmentally friendly and low-cost.
Physiological monitoring can be provided through an actigraphy sensor imbedded into an electrocardiography monitor, which correlates movement and electrocardiographic data. Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum. The patient can place an electrode patch anywhere within the general region of the sternum. The occurrence of actigraphy events are monitored by the monitor recorder through an actigraphy sensor. Actigraphy becomes a recordable actigraphy event occurrence when the movement of the wearable monitor and, therefore, the patient, exceeds a certain criteria threshold of acceleration or deceleration as detected by the actigraphy sensor. Certain actigraphy event occurrences as recorded by the monitor recorder are considered to be actionable, that is, of sufficient importance to warrant flagging for further consideration to a following physician.

Monitor recorder-implemented method for electrocardiography data compression
A monitor recorder-implemented method for electrocardiography data compression and an electrocardiography monitor recorder with integral data compression are provided. A series of data items are obtained, each of the data items associated with a magnitude of an ECG signal sensed by a monitor recorder. A range is set for an initial one of the data items in the series. Each of the data items remaining in the series is processed, including: obtaining an estimation of probabilities of the data items appearing next to that data item in the series; dividing the further range into sub-ranges, each sub-range representing a fraction of the further range proportional to the probabilities of the next data items; selecting the sub-range corresponding to the data item next to that data item in the series; and representing the next data item by the selected sub-range in a non-volatile memory.
Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally (in the midline) on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. Instead, the patient can place an electrode patch anywhere within the general region of the sternum. Power is provided through a battery provided on the electrode patch, which avoids having to open the monitor recorder's housing for battery replacement.

System and method for providing dynamic gain over non-noise electrocardiographic data with the aid of a digital computer
In one embodiment, a system and method for providing dynamic gain over non-noise electrocardiographic data with the aid of a digital computer are provided. A time series of a plurality of voltage values that comprises a digital representation of a raw electrocardiography (“ECG”) signal recorded by an ambulatory monitor recorder is obtained. One or more segments of the ECG signal is marked as noise, each of the segments including a plurality of the values, based on a difference between a maximum one and a minimum one of the values within that segment. Further segments not marked as noise are analyzed, each of the segments comprising a plurality of the values. A gain factor for all of the values in the analyzed further segments is determined based on the analysis.
Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch with sewn electrodes and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.
Physiological monitoring can be provided through a wearable monitor that includes a flexible extended wear electrode patch and a removable reusable monitor recorder. A pair of flexile wires is interlaced or sewn into a flexible backing, serving as electrode signal pickup and electrode circuit traces. The wearable monitor sits centrally on the patient's chest along the sternum, which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. The electrode patch is shaped to fit comfortably and conformal to the contours of the chest approximately centered on the sternal midline. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive is provided on the underside, or contact, surface of the electrode patch, but only on the distal and proximal ends. Interlacing or sewing the flexile wires into the flexile backing also provides structural support and malleability against compressional, tensile and torsional forces.
