    摘要: A defibrillator incorporates an analyser (2) arranged to receive signals from a patient's heart (such as from electrode pads (6) placed on the patient's chest). A charging circuit (4) enables the electrodes (6) to deliver a charge from the charging circuit to the patient. The analyser is arranged to compare one or more heart rhythm sequences from the patient with predetermined data relating to a heart rhythm and, depending on a result of an initial part of comparison, the analyser is arranged to activate starting of charging of the charging circuit, whilst comparison continues, in readiness for possible delivery of a shock to the patient.

    摘要: Methods and systems for defibrillation therapy involve delivering a pre-shock waveform to cause contraction of skeletal musculature in the patient's thorax before delivering a defibrillation waveform. A shock is delivered to the patient's heart during contraction of the skeletal musculature for a reduction in defibrillation threshold. The pre-shock waveform is sufficient in energy to cause one or both of deflation of the patient's lungs and muscle fiber shortening of the skeletal musculature. A delay interval may be initiated relative to delivery of the pre-shock waveform, wherein the defibrillation waveform is delivered following expiration of the delay interval. Motion of the patient's thorax and/or expiration of the patient's lungs may be detected, responsive to the pre-shock waveform. The defibrillation waveform may be delivered in coordination with the detected parameter, such as in relation to detection of a peak in the thoracic motion or minimum in transthoracic impedance.

    摘要: Miniature defibrillators and cardioverters detect abnormal heart rhythms and automatically apply electrical therapy to restore normal heart function. Critical to this function, aluminum-electrolytic capacitors store and deliver life-saving bursts of electric charge to the heart. This type of capacitor requires regular nullreformnull to preserve its charging efficiency over time. Because reform expends valuable battery energy, manufacturers developed wet-tantalum capacitors, which are generally understood not to require reform. Yet, the present inventors discovered through extensive study that wet-tantalum capacitors exhibit progressively worse charging efficiency over time. Accordingly, to address this problem, the inventors devised unique reform techniques for wet-tantalum capacitors. One exemplary technique entails charging wet-tantalum capacitors to a voltage equal to about 90% of their rated voltage and allowing the charge to dissipate through system leakage for a period of time, before discharging through a non-therapeutic load.

    摘要: A dosage for electrotherapy delivered to a patient, such as a defibrillation pulse delivered by an external defibrillator, is selected based on an age-related classification, such as adult or child, and a measured electrical parameter, such as the transthoracic impedance, of the patient. For example, a nominal voltage level for an energy storage circuit may be determined based on a nominal dosage. The nominal voltage level may be adjusted by applying a function that relates voltage level adjustment to impedance to the measured impedance. The function may be selected based on the age-related classification of the patient. The dosage of the defibrillation pulse delivered based on the adjusted voltage level, i.e., the selected dosage, may have a substantially equivalent probability of success for the patient as the nominal dosage would provide for a reference patient with an average transthoracic impedance for the class of which the patient is a member.

    摘要: A defibrillation circuit generates a defibrillation pulse and includes a patient-parameter compensator that causes the pulse to have a predetermined characteristic regardless of the value of a patient parameter. For example, the circuit can generate defibrillation pulses that have a desired shape, decay rate, voltage level, current level, and/or energy level regardless of the patient impedance. Consequently, a defibrillator that includes the circuit is likely to be more effective than prior defibrillators in restoring normal heart rhythms to patients having an atypical value for a parameter such as impedance.
