A method for data exchange and charging is provided. An implantable medical device is monitored and charging of the implantable medical device is initiated by providing charge parameters to a bedside monitor. Communication is initiated between a puck associated with the bedside monitor and implantable medical device. The implantable medical device is charged using the charge parameters. Simultaneously with the charging, transfer of data between the implantable medical device and the bedside monitor is initiated.

SYSTEM FOR INDUCTION-BASED SUBCUTANEOUS INSERTABLE PHYSIOLOGICAL MONITOR RECHARGING
An insertable cardiac monitor (ICM) with induction-based recharging capabilities and a transmitting coil for recharging the same are disclosed. The length of the monitoring performed by the ICM is extended and the functionality of the ICM enhanced, by including an internal energy harvesting module that allows for charging the ICM at a high speed without burning the patient or overheating components of the ICM. Internally, the energy harvesting module includes at least two overlapping receiving coils that are spaced to be orthogonal to each other and that have a tilt angle of substantially 45 . Such overlapping wire combination allows to minimize mutual inductance of the solenoid coils and increase the rate at which energy can be provided to the energy harvesting module. Further, the rate at which the energy is transmitted from the outside can be increased by defining in a transmitting coil a substantially triangular gap.

SYSTEM AND METHOD FOR LONG-TERM PATIENT MONITORING OF CONTINUOUS ECG AND PHYSIOLOGICAL DATA
A method for continuous data transfer is provided. Data blocks are generated from a continuous data stream captured via a physiological monitoring device by segmenting data from the continuous data stream into the data blocks. A time at which the data associated with each data block occurs is determined and a sample number is associated with each data block. The data blocks are transmitted from the physiological monitoring device to a server. The data blocks are ordered on the server based on the time and the sample number associated with each data block.

A61B 5/318 - Heart-related electrical modalities, e.g. electrocardiography [ECG]
An insertable physiological monitor injector tool is provided. An elongated handle (11) includes a recess (12) formed along a longitudinal axis and has an opening on a distal end. An insertion tube (16) has a hollow elongated shape that is movably positioned within the elongated handle (11), in the recess (12). A stationary arbor (15) is affixed on a proximal end to a proximal end of the elongated handle (11) and extends through the insertion tube (16) when the insertion tube (16) is in a retracted position. A tab (18) is affixed to the insertion tube (16), wherein the tab (18) can lock the insertion tube (16) in an extended position.
A system (140) for facilitating a cardiac rhythm disorder diagnosis is provided. A download station (145) retrieves cutaneous action potentials of a patient recorded over a time by an ECG device (142) as ECG data. An R-R interval plot (53) of the ECG data includes R-R intervals plotted along an x-axis of the plot (53) and heart rates associated with the R-R intervals plotted along a y-axis. The R-R intervals are calculated as a difference between recording times of successive pairs of R-wave peaks. Each heart rate is associated with each time difference. One or more portions of the R-R intervals are identified in the plot (53). Each portion of the R-R intervals includes a cardiac event. Report strips (442) are generated and each includes one portion of the R-R intervals and a portion of the ECG data. The report strips (442) are included in a cardiac report.
Physiological monitoring can be provided through a syncope sensor (64, 66) embedded into an electrocardiography monitor (12), which correlates syncope events and electrocardiographic data. Physiological monitoring can be provided through a lightweight wearable monitor (12) that includes two components: a flexible extended-wear electrode patch (15) and a reusable monitor recorder (14) that removably snaps into a receptacle (25) on the electrode patch (15). The wearable monitor (12) sits centrally on the patient's sternal midline (16) and includes a unique narrow "hourglass"- like shape, significantly improving the ability of the monitor to cutaneously sense cardiac electrical potential signals, particularly the P- wave and QRS interval signals. The electrocardiographic electrodes (38, 39) on the electrode patch (15) are tailored for axial positioning along the midline (16) of the sternum (13) to capture action potential propagation in an orientation that corresponds to the aVF lead in a conventional 12-lead electrocardiogram, which senses positive P-waves (271).
R-R interval data is presented (24) in a format that includes relevant near field and far field ECG data. The near field view (51) provides a "pinpoint" classical view at classical recording speed. The far field view (52) provides an "intermediate" lower resolution, pre- and post-event view. Both ECG data views (51, 52) are temporally keyed to the extended duration R-R interval data (53) that is scaled non-linearly to maximize the visual differentiation for frequently-occurring heart rate ranges. The views (51, 52, 53) are presented simultaneously and their durations are flexible and adjustable. Diagnostically relevant cardiac events can be identified (23) and located to allow pre- and post-event heart rhythm data. The pinpoint "snapshot" and intermediate views of ECG data (56, 166) with the extended term R-R interval data (53) comparatively depicts heart rate context and patterns of behavior prior to and after a clinically meaningful arrhythmia or patient concern.
A method (200) for efficiently encoding and compressing ECG data optimized for use in an ambulatory electrocardiography monitor is provided. ECG data is first encoded and compressed (202) in a lossy process and further encoded and compressed (203) in a lossless process. A compression ratio significantly higher than other Holter-type monitors is achieved. Requirements for storage space and power cell consumption are reduced, contributing to the long-term availability of the monitor.
