Abstract: Methods and apparatuses, including devices and systems, for remote and detection and/or diagnosis of acute myocardial infarction (AMI). In particular, described herein are handheld and adhesive devices having an electrode configuration capable of recording three orthogonal ECG lead signals in an orientation-specific manner, and transmitting these signals to a processor. The processor may be remote or local, and it may automatically or semi-automatically detect AMI, atrial fibrillation or other heart disorders based on the analyses of the deviation of the recorded 3 cardiac signals with respect to previously stored baseline recordings.

Abstract: Compact, mobile three-lead cardiac monitoring devices for remote detection and/or diagnosis of cardiac events (e.g., acute myocardial infarction). The apparatus may include two integrated hand electrodes and two chest electrodes disposed on two pivotable arms that are capable of retracting in the compartments, enabling a compact size when the device is not used. Also described herein are systems including these devices and methods of using them.

Abstract: Wrist-wearable apparatuses that may be removed and used as a chest-applied cardiac device may include two chest electrodes on an inner surface of a strap (or strap regions), as well as two finger or more finger electrodes on the opposite side of the apparatus. The apparatus may be removed from the wrist and placed on a chest of a patient such that two electrodes are spaced at least five centimeters apart and in contact with the chest and held in place with two or more fingers to capture orthogonal cardiac signals that may be synthesized into a conventional 12-lead cardiac signal.

Abstract: Systems and apparatus for synthesizing (generating) 12-lead ECG dataset from 3-lead ECG data. In particular, one or more transformation parameters may be determined that may be applied to 3-lead ECG dataset to generate 12-lead ECG data with particular speed and accuracy. The transformation parameters, which may include a plurality of matrices, may be determined from a synchronized patient's 12-lead ECG dataset and 3-lead ECG data. The 12-lead ECG dataset may be collected at a different time than the 3-lead ECG data. In some embodiments, the 12-lead ECG dataset and/or the 3-lead ECG dataset may be resampled prior to determining the transformation parameters.

Abstract: 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.

Abstract: Systems and methods for characterizing aspects of an electrocardiogram signal are presented, wherein data quality and stability analysis paradigms are utilized to determine the timing certain cardiac electronic events with precision. In one embodiment, confidence factor calculation may be utilized to filter out nonusable ECG signals to leave a usable beat dataset, and this usable beat dataset may be utilized with moving window stability analysis to determine data most suitable extracted from a larger set to represent such larger set. The system may comprise a processor or microcontroller embedded into another system such as an electrocardiogram hardware system, personal computer, electrophysiology system, or the like.
