Abstract: An embodiment of the invention provides a heart rate detection device. The heart rate detection device may include an electrocardiography (ECG) signal extraction circuit, a detection circuit, a calculation circuit and a filter. The ECG signal extraction circuit obtains an ECG signal. The detection circuit detects a plurality of R-waves in the ECG signal. The calculation circuit uses the first of the R-waves as the initial point from which to calculate the standard deviation of the R-waves in each moving window. The calculation circuit determines whether the standard deviation corresponding to each moving window is larger than the first threshold. The calculation circuit determines whether the number of moving windows whose corresponding standard deviation exceeds the first threshold is larger than a second threshold to generate a determination result. Furthermore, the calculation circuit determines whether to use the filter to filter the ECG signal based on the determination result.

Abstract: A method for evaluation of electrical propagation in the heart includes receiving a pacing signal applied to a heart of a patient, the pacing signal including a sequence of normal and shorter, abnormal, pacing stimuli. A responsive cardiac signal is received, that is sensed by electrodes at a location in the heart and on the body surface of the patient. A model response is found and annotated from evoked potentials caused by the normal pacing stimuli. A correlation is made between the model response along the different signal sections to find and calculate a normal and decremental time delays between the pacing stimuli and respectively resulting evoked potentials at a tissue location. A time difference is calculated, between the normal time delay and the decremental time delay. An EP map of at least a portion of the heart is presented to a user, with a graphical indication of the time difference presented at the tissue location.

Abstract: A wearable cardioverter defibrillator system includes a support structure that a patient can wear. The system also includes electrodes that contact the patient, and define two or more channels from which ECG signals are sensed. A processor may evaluate the channels by analyzing their respective ECG signals, to determine which contains less noise than the other(s). The analysis can be by extracting statistics from the ECG signals, optionally after first processing them, and then by comparing these statistics. These statistics may include tall peak counts, amplitudes of peaks compared to historical peak amplitudes, signal baseline shift, dwell time near a baseline, narrow peak counts, zero crossings counts, determined heart rates, and so on. Once the less noisy signal is identified, its channel can be followed preferentially or to the exclusion of other channels, for continuing monitoring and/or determining whether to shock the patient.
