Abstract:
A method of treating a patient for cardiac arrhythmia using a defibrillator, the method comprising the steps of:monitoring the patient for a predetermined condition via one or more electrodes on the defibrillator; sending a message from said defibrillator to the patient in response to the predetermined condition; activating the defibrillator so that the defibrillator delivers defibrillation energy to the patient; storing information related to at least one of the results of the monitoring, sending and activating steps in a memory on the defibrillator; and transmitting said information to an external location; wherein at least one of the electrodes is used to monitor a transthoracic impedance of the patient; and wherein the defibrilliation energy comprises an electrical signal having a bi-phasic waveform which varies in accordance with the transthoracic impedance of the patient.
