Patent number: 8311618Abstract: Method and apparatus for computer enabled analysis of ECG (electro cardiographic) data by exploiting computerized three-dimensional spatial presentation of the measured data using vectors. A three-dimensional presentation of the human heart may be correlated with waveforms specific for standard ECG or derived ECG signals based on the dipole approximation of the heart electrical activity. Additional tools for analyzing ECG data are also provided which may be used to determine the time of cardiac electrical events, to select specific beats for automated cardiac interval determination, and to flag ECGs that have been evaluated by automated means but may benefit by human reading.Type: GrantFiled: January 3, 2011Date of Patent: November 13, 2012Assignee: New Cardio, Inc.Inventors: Branislav Vajdic, Alexander D.

Publication number: 20100179446Abstract: The analysis of ECG (electrocardiogram) data by exploiting computerized three-dimensional spatial presentation of the measured data using the vector concept. A three-dimensional presentation of the human heart may be correlated with waveforms specific for standard ECG or derived ECG signals based on the dipole approximation of the heart electrical activity. The three-dimensional heart model may be rotated, and the ECG signals are interactively linked to the model. Cardiac ischemia (inadequate blood supply) is detected by calculating an ECG ST-segment vector magnitude or an ST-T spatial angle change of a heart vector from the heart model and comparing these to respective predetermined ischemia criteria, using actual or virtual ECG lead sites.Type: ApplicationFiled: March 17, 2010Publication date: July 15, 2010Applicant: NewCardio, Inc.Inventors: Bosko Bojovic, Ljupco Hadzievski, Petar Belicev
