Abstract: Electronic medical records (EMRs) with the results of the monitoring can be stored in a cloud-computing environment. All communications with the cloud-computing environment are performed via a secure connection. Each of the EMRs can be associated with an identifier that is provided with the results of the monitoring data. The EMRs can be created, viewed, and modified using a mobile application. The mobile application can use a scanner in the mobile device on which the application executes to obtain an identifier and uses the identifier to direct actions of the user towards the appropriate EMR. The mobile application can further provide additional user access verification. Alerts can further be provided through the mobile application. The mobile application deletes from the mobile device all information that has been transmitted or received from the cloud-computing environment once the information is no longer used.

Abstract: A subcutaneous insertable cardiac monitor (ICM) for use in performing long term electrocardiographic (ECG) monitoring is disclosed. The length of the monitoring performed by the ICM is extended, potentially for a life time of the patient, and the functionality of the ICM is enhanced, including enhancing the rate at which data can be offloaded from the ICM, by including an internal energy harvesting module in the ICM. The energy harvesting module harvests energy from outside the ICM, and provides the harvested energy for powering the circuitry of the ICM, either directly or by recharging a power cell within the ICM. As the circuitry of the ICM requires a low amount of electrical power, the harvested energy can be sufficient to support the functioning of the ICM even when the electrical power stored on the ICM at the time of implantation runs out.

Abstract: A system for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer is provided. A download station retrieves cutaneous action potentials of a patient by an ECG monitoring and recording device as ECG data. An R-R interval plot of the ECG data includes heart rates associated with R-R intervals plotted along a y-axis of the plot with respect to time, with time represented by an x-axis. The R-R intervals are calculated as a difference between recording times of successive pairs of R-wave peaks and each heart rate is associated with each time difference. Runs of the R-R intervals in the plot are identified and each run represents a cardiac event. Cardiac rhythm measurements are automatically calculated and occurrences of different types of the cardiac events are tracked. One or more of the cardiac events and the cardiac rhythm measurements are reported.
