Patent number: 8041416Abstract: A method of assessing a patient's susceptibility to ventricular arrhythmia obtaining data by applying electrodes to detect electrocardiographic signal. A plurality of synchronized subthreshold electrical stimuli are delivered into the patient's body to present stimulated cardiac cycles to the electrodes and unstimulated reference cardiac cycles to the electrodes the signals are analyzed by creating a matrix of vectorized time-phase data representing a plurality cardiac cycles contained in the electrocardiographic signals that are recorded the method includes processing the matrix to generate spectral analytic representation of the matrix, analyzing at least the spectral analytic representation to determine at least one alternans index for the patient; and displaying the at least one alternans index as an indicator of the patient's susceptibility to arrhythmia.Type: GrantFiled: September 18, 2007Date of Patent: October 18, 2011Assignee: Harbinger Medical, Inc.Inventors: Harold H. Hoium, James Brewer

Patent number: 7610091Abstract: A system and method for detecting lead adequacy and quality is disclosed. The system includes leads attached to a package having known electrical or optical characteristics. The package is adapted to interface with a testing device that allows the operator to ascertain whether the leads are appropriate for the desired task. This allows the testing of the lead set without the need to remove it from the package. The system of the present invention generally includes packaging of known electrical or optical characteristics, a package testing interface, and a lead testing assembly including hardware and/or software to determine whether the leads in question fulfill the desired characteristics. The lead testing assembly may be freestanding or may be incorporated into an existing testing instrument.Type: GrantFiled: November 16, 2006Date of Patent: October 27, 2009Assignee: Harbinger Medical, Inc.Inventors: Harold H. Hoium, Stephen J. Ryan

Patent number: 7171265Abstract: 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.Type: GrantFiled: September 20, 2001Date of Patent: January 30, 2007Assignee: Harbinger Medical, Inc.Inventors: Harold H.

Patent number: 7016731Abstract: Sensing artifacts in cardiac signals picked up by electrical leads are reduced by placing an electrical shunting switch across the conductors of the ECG sensing leads and the stimulation leads that deliver a subthreshold electrical stimulation. In addition, impedance switches are placed in series with the sensing leads. The shunting switches and impedance switches are then manipulated to present cardiac signals that can be analyzed for diagnostic purposes within less than 100 ms from delivery of a subthreshold electrical stimulation.Type: GrantFiled: June 27, 2003Date of Patent: March 21, 2006Assignee: Harbinger Medical, Inc.Inventors: Stephen J. Ryan, Harold H. Hoium

Patent number: 6850795Abstract: A system and method for detecting a patient's susceptibility to arrhythmias and cardiac tissue abnormality is disclosed. The method consists of using a computer 27, a display 23, software loaded onto the computer that generates graphical user interfaces (GUIs), an electronic interface 18, and a plurality of electrodes. The electronics interface 18 is in electronic communication with the computer 27, and further in electronic communication with the electrodes that are placed by self-adhesion at predetermined locations on a test subject 35. 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 130, 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 patient's susceptibility to arrhythmias and cardiac tissue abnormality.Type: GrantFiled: January 9, 2003Date of Patent: February 1, 2005Assignee: Harbinger Medical, Inc.Inventors: Harold H. Hoium, Stephen J. Ryan, Marek Malik
