Abstract: Medical apparatus and methods for diagnostic and site determination of cardiac arrhythmias within a heart of a subject are provided. A computing device receives, records and processes electrocardiogram (ECG) signals in the form of bipolar and unipolar ECGs associated with respective cardiac tissue locations corresponding to catheter distal end sensors on locations. Unipolar ECGs that include signals from a plurality of successive heartbeats corresponding to locations within an area of study are analyzed to identify Fractionated Unipolar ECG Signal Complexes (FUESCs) of unipolar ECGs by defining complexes of the unipolar ECGs that correspond to respective bipolar activity windows. Identified arrhythmia sites for treatment include a predetermined number of unipolar ECGs that have a predetermined number of FUESCs. Atrial arrhythmia sites for treatment by ablation can be identified with respect to FUESCs of unipolar ECGs that include signals from at least ten successive heartbeats of an atrial tissue study area.

Abstract: A medical system is provided. The medical system includes a processing device communicatively coupled to a probe. The processing device operates to cause the medical system receive physiological signals from electrodes of the probe and decompose the physiological signals into near-field component and far-field component by using mutual information from a set of the electrodes. The processing device operates to cause the medical system utilize the near-field components for localizing in time where a wave went under at least one of the plurality of electrodes.

Abstract: A device is described for analyzing electrocardiogram data. The device comprises processing means for comparing at least one parameter derived from a temporal sequence of electrocardiogram data a previously recorded distribution of that parameter obtained from the user under a plurality of different physiological conditions. Based on the comparison, a signal representative of a risk of a myocardial infarction occurring in the body of the user is provided. A corresponding method, device and computer application for installing on a user device are also described.

Abstract: A device for analyzing electrophysiological data is disclosed.

Abstract: A device 1 is described for analyzing electrocardiogram data. The device comprises processing means for comparing at least one parameter, indicative of a morphological feature comprising a multi-dimensional ST segment feature, derived from a temporal sequence of electrocardiogram data to a previously determined distribution of the at least one parameter. Based on the comparison, a signal representative of a risk of a myocardial infarction occurring in the body of the user is provided. A corresponding method and device are also described. The electrocardiogram data comprises a bipolar measurement between a chest electrode point and the right upper extremity, a bipolar measurement between the left crista iliaca and the right upper extremity and a bipolar measurement between the left and the right upper extremity.
