Abstract
A cardiac pacer analysis system which is external to the patient is provided for an implanted pacer having patient history stored within the pacer. Information is transmitted from the pacer, and is received, stored and processed. Events in the received information are identified and characterized, observed problems are identified, probable causes of observed problems are indicated and possible corrective actions are provided. The results of the analyses are displayed for the clinician.
Claims16
A cardiac pacer analysis system, which comprises:
- means for receiving and storing information telemetrically transmitted from an implanted pacer;
- means for identifying and characterizing events in the received information;
- means for identifying observed problems that are based on the events and on logical rules which express the functioning relationships incorporated in the operation of the implanted pacer;
- means for automatically determining probable causes of observed problems and possible corrective actions;
- and
- means for displaying the results of the automatic determinations to a clinician by including selected clinically relevant information.
A cardiac pacer analysis system which comprises:
- a signal receiving and storage means for accepting surface ECG and telemetrically transmitted information from the pacer and storing said information;
- a digital signal processing means responsive for the signal receiving and storing means for identifying and characterizing the received ECG data;
- an ECG event analysis means responsive to the digital signal processing means for automatically determining if the pacer functioned correctly and produced the clinically desired response from the patient at each ECG event;
- a clinical analysis and advisor means responsive to the ECG event analysis means for automatically summarizing the results and identifying any observed problems and automatically providing probable causes and possible actions that a physician can take to alleviate the observed problem;
- and
- a results output means for automatically presenting results of the ECG event analysis and the clinical event analysis by including selected relevant clinical information to a clinician.
A cardiac pacer analysis system for use with a cardiac pacer in which patient history information is stored within the pacer, which comprises:
- storage means containing a knowledge base encompassing the functional characteristics of the pacer;
- means for automatically receiving information including surface ECG information and telemetered ICEGs from the pacer;
- means for automatically sorting by time and type of signal the received information signals and providing a sampling segment;
- means for automatically examining each sampling segment to determine if the pacer functions properly;
- and
- means for automatically analyzing the received information to provide a comprehensive assessment of the implanted pacer.
A system as described in claiim 7, in which the information received includes pacer parameter programmed values, pacer stored patient-related information, results of automatically performed pacer measurements, and a surface ECG signal presented as an analog signal.
A cardiac pacer analysis system which comprises:
- means for receiving and storing telemetrically transmitted information, including pacer parameter programmed values, pacer stored patient-related information, results of automatically performed pacer measurements, and a surface ECG signal presented as an analog signal;
- means for automatically sorting the signals and producing a sampling segment;
- means for automatically detecting cardiac activity and correlating the detected cardiac activity with a previously identified pacer action;
- means for automatically sorting the identified events;
- means for automatically examining each event and determining if the pacer functions properly;
- and
- means for automatically providing a comprehensive evaluation of the implanted pacer.
