Filed:

Jan 19, 2000

Appl. No.:

09/487557

Inventors:

Harold H. Hoium - Eden Prairie MN
Stephen J. Ryan - Chaska MN
Marek Malik - London, GB

Assignee:

Harbinger Medical, Inc. - Eden Prairie MN

International Classification:

A61B 50452

US Classification:

600515, 600518

Abstract:

A system and method for detecting a patients susceptibility to arrhythmias and cardiac tissue abnormality is disclosed. The method consists of using a computer, a display, software loaded onto the computer that generates graphical user interfaces (GUIs), an electronic interface, and a plurality of electrodes. The electronics interface is in electronic communication with the computer, and further in electronic communication with the electrodes that are placed by self-adhesion at predetermined locations on a test subject. According to one aspect of the invention, the method enables a user, typically a medical professional, to initiate, with minimal input, certain diagnostic tests involving observing and analyzing a series of QRS complexes, some of which are biased with a subpacing current, and others of which are unbiased. The signals are then compared, and the differences are analyzed to detect a patients susceptibility to arrhythmias and cardiac tissue abnormality.

Abstract:

A system and method for detecting a patients susceptibility to arrhythmias and cardiac tissue abnormality is disclosed. The method consists of using a computer, a display, software loaded onto the computer that generates graphical user interfaces (GUIs), an electronic interface, and a plurality of electrodes. The electronics interface is in electronic communication with the computer, and further in electronic communication with the electrodes that are placed by self-adhesion at predetermined locations on a test subject. According to one aspect of the invention, the method enables a user, typically a medical professional, to initiate, with minimal input, certain diagnostic tests involving observing and analyzing a series of QRS complexes, some of which are biased by passively altering the impedance of the patients body, and others of which are unbiased. The signals are then compared, and the differences are analyzed to detect a patients susceptibility to arrhythmias and cardiac tissue abnormality.

Abstract:

A method and system for detecting lead adequacy and quality for leads used in devices that sense or deliver low levels of electromagnetic energy. The system includes leads attached to a package substrate having known electrical or optical characteristics. The package is adapted to interface with a testing device that allows an operator to ascertain whether the leads are appropriate for a desired task. The operator need not remove the leads from the package to perform the test. The lead testing system may be freestanding or integrated into a lead utilizing instrument.
