    Abstract: Apparatuses and methods are provided for automatically determining which type of resuscitation treatment is most appropriate for a patient. Methods are provided that include the following. One or more time domain signal measurements are transformed into frequency domain data representative of a frequency content of the one or more time domain signal measurements. The frequency domain data is processed to identify peaks. For each of the peaks, for each of multiple points in time, multiple parameters of the peak are determined. Based on the multiple parameters of the peaks for each of the multiple points in time, a trajectory is determined. The determined trajectory is analyzed in determining a recommended type of resuscitation treatment. An output indication is provided of the recommended type of resuscitation treatment.

    Abstract: A defibrillation system for synchronized cardioversion of a patient includes a first housing that includes a measurement circuit configured to receive electrocardiogram (ECG) signals and measure ECG parameters based on the ECG signals, and a first processor configured to analyze the ECG parameters, and initiate communication of a synchronization signal for a second processor for delivery of one or more defibrillation pulses and further includes a second housing that is separate from and external to the first housing and that includes a shock delivery circuit, and the second processor which is configured to receive the communication of the synchronization signal from the first processor, and control the shock delivery circuit to deliver the one or more defibrillation pulses in response to the synchronization signal.

    Abstract: Apparatus for automatically determining which type of resuscitation treatment is most appropriate for a patient. The apparatus comprising at least one processor, circuitry for delivering time-domain signal measurements to the processor(s), which transforms the time-domain signal measurements into frequency domain data representative of a frequency content of the time-domain signal measurements, processes the frequency domain data to form a plurality of spectral bands, a content of each of the plurality of spectral bands representing the frequency content of the time-domain signal measurements within a different frequency band, form a weighted sum of the content of the plurality of spectral bands, with different weighting coefficients applied to the plurality of spectral bands, wherein magnitudes of the weighting coefficients are non-linearly proportional to frequencies of the plurality of spectral bands to which the weighting coefficients are applied, and determines the type of resuscitation treatment based on the weighted sum.
