Abstract
A system and method for a multi-function remote ambulatory cardiac monitoring system. The system includes a housing and a microprocessor disposed within the housing. The microprocessor controls the remote ambulatory cardiac monitoring system. The system also includes an electrode for sensing ECG signals and the electrode being in communication with the microprocessor. An integrated cellular module also is included in the system, and the cellular module is connected to the microprocessor and disposed within the housing. The integrated cellular module transmits ECG signals to a remote center.
Core Innovation
The invention relates to a remote ambulatory cardiac monitoring system that includes an ambulatory housing with a microprocessor disposed within the ambulatory housing and an electrode for sensing ECG signals in communication with the microprocessor. The electrode is communicatively coupled to the ambulatory housing, and the microprocessor controls monitoring of ECG signals while the system is ambulatory.
The microprocessor is configured to switch among a plurality of different modes, where the plurality of different modes comprises at least two of an EKG/ECG mode, an ECG Holter mode, and an MCT/Event mode. The disclosure further emphasizes smart mode switching based on electrode/cable set information and includes multiple operational modes, such as resting 12-lead EKG, ECG Holter, MCT/Event, and USB transfer.
The system includes functionality such as electrode lead/leadoff impedance measurement and noise cancellation using dynamic right-leg-drive with three-electrode operation and derived channels using Einthoven’s law. It further includes wireless and backup event transmission, remote parameter adjustment, and real-time arrhythmia detection algorithms for event types including sinus pause, bradycardia, tachycardia, and atrial fibrillation using a PDF/phase-space reconstruction approach.
Claims Coverage
Independent claim clm-00001 defines a remote ambulatory cardiac monitoring system with a microprocessor-based multi-mode switching architecture, covering at least EKG/ECG, ECG Holter, and MCT/Event modes. The independent-claim coverage also encompasses additional independent claim members refining the system toward specific transmission and operating-mode behaviors, as reflected in the provided family summary for claim members.
Remote ambulatory cardiac monitoring system with in-housing microprocessor and ECG electrode
A remote ambulatory cardiac monitoring system comprising an ambulatory housing; a microprocessor for controlling the remote ambulatory cardiac monitoring system disposed within the ambulatory housing; and an electrode for sensing ECG signals communicatively coupled to the ambulatory housing.
Microprocessor-controlled switching among EKG/ECG, ECG Holter, and MCT/Event modes
The microprocessor is configured to switch among a plurality of different modes of the remote ambulatory cardiac monitoring system, wherein the plurality of different modes comprises at least two of an EKG/ECG mode, an ECG Holter mode, and an MCT/Event mode.
Integrated cellular module for transmitting ECG signals within the ambulatory housing
An integrated cellular module connected to the microprocessor to transmit ECG signals, wherein the cellular module is housed within the ambulatory housing rather than in a separate device housing.
User-interface detection for selecting operating modes
An ambulatory housing user interface module that can detect a user’s selection of one of multiple different operating modes.
Condition-based switching from ECG Holter mode to MCT/Event mode
The microprocessor switches from an ECG Holter mode to an MCT/Event mode when the ECG Holter mode is negative after at least a 24-hour period.
USB data transfer mode among the plurality of monitoring modes
The system includes a USB data transfer mode among its plurality of different modes.
Arrhythmic-event detection for specific event types
Arrhythmic events include sinus pause, bradycardia, bradycardia time offset, tachycardia, or atrial fibrillation.
Overall, the claim coverage centers on a remote ambulatory system with an in-housing microprocessor controlling ECG sensing and multi-mode switching among EKG/ECG, ECG Holter, and MCT/Event modes, refined by integrated cellular transmission, user-interface mode selection, condition-based mode switching from Holter to MCT/Event, a USB transfer mode, and arrhythmia-event detection for enumerated event types.
