Abstract
A system to detect a cause of a complex rhythm disorder in a human heart includes a plurality of sensors disposed spatially in relation to the heart, where the signals generated by the sensors are associated with activations of the heart. A processor collects and analyzes the signals to identify a region of the heart having an activation trail that is rotational or radially emanating, where the activation trail is indicative of the complex rhythm disorder and is based on activation times associated with the activations of the heart.
Claims51
A system to detect a cause of a heart rhythm disorder, the system comprising:
- a plurality of sensors disposed at multiple locations in relation to the heart to sense heart activation signals;
- a processor interfacing with the plurality of sensors, wherein the processor is configured to:
- collect from the plurality of sensors data associated with the heart activation signals, the data comprising an activation onset time of each heart activation signal at each location such that a plurality of activation onset times at a plurality of locations is collected;
- and
- generate an activation trail from the data based on the sequential order of the plurality of activation onset times at the plurality of locations, the activation trail indicative of the cause of the heart rhythm disorder.
A system to detect a cause of a biological rhythm disorder, the system comprising:
- a plurality of sensors disposed at multiple locations in relation to an organ to sense biological activation signals;
- a processor interfacing with the plurality of sensors, wherein the processor is configured to:
- collect from the plurality of sensors, data comprising an activation onset time of each biological activation signal at each location such that a plurality of activation onset times at a plurality of locations is collected;
- and
- generate an activation trail from the data based on a sequential order of the plurality of activation onset times at the plurality of locations, the activation trail indicative of the cause of the biological rhythm disorder.
