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.

ECG rhythm advisory method

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.

Multi-path transthoracic defibrillation and cardioversion

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.

A method of automatically determining which type of treatment is most appropriate for a cardiac arrest victim, the method comprising transforming one or more time domain electrocardiogram (ECG) signals into a frequency domain representation comprising a plurality of discrete frequency bands, combining the discrete frequency bands into a plurality of analysis bands, wherein there are fewer analysis bands than discrete frequency bands,

A method of automatically determining which type of treatment is most appropriate for (or the physiological state of) a patient. The method comprises transforming one or more time domain measurements from the patient into frequency domain data representative of the frequency content of the time domain measurements; processing the frequency domain data to form a plurality of spectral bands, the content of a spectral band representing the frequency content of the measurements within a frequency band; forming a weighted sum of the content of the spectral bands, with different weighting coefficients applied to at least some of the spectral bands; determining the type of treatment (or physiological state) based on the weighted sum.

Aspects of the invention are directed to advanced monitoring and control of medium voltage therapy (MVT) in implantable and external devices. Apparatus and methods are disclosed that facilitate dynamic adjustment of MVT parameter values in response to new and changing circumstances such as the patient's condition before, during, and after administration of MVT. Administration of MVT is automatically and dynamically adjusted to achieve specific treatment or life-support objectives, such as prolongation of the body's ability to endure and respond to MVT, specifically addressing the type of arrhythmia or other pathologic state of the patient with targeted treatment, a tiered-intensity MVT treatment strategy, and supporting patients in non life-critical conditions where the heart may nevertheless benefit from a certain level of assistance.
