    摘要： A defibrillator system employs an external ECG monitor (40) and a defibrillator (20). In operation, external ECG monitor (40) generates a synchronized cardioversion input signal as one of an external ECG waveform (50) of a heart (11) of a patient (10) or an external synchronized pulse (51) indicative of a detection by the external ECG monitor (40) of at least one QRS complex of the external ECG waveform (50). Defibrillator (40) includes a synchronized cardioversion input channel (29) for receiving the synchronized cardioversion input signal from external ECG monitor (40), and controls a conditional delivery of a defibrillation shock synchronized with the synchronized cardioversion input signal to the patient (10) in response to the defibrillator (20) receiving the synchronized cardioversion input signal. One condition for shock delivery is a measured time delay between an internal ECG waveform (30) and the synchronized cardioversion input signal being less than a baseline time delay.

    摘要： An electrode identification system (1) for defibrillators, comprising an electrode plug (2) adapted for connection to at least one electrode having a first pair of conducting contacts (6, 8), an identification element (10) connected between the first pair of conducting contacts, a second pair of conducting contacts (12, 14) for connection to the electrode, and a housing (16) providing a cavity (18, 20) which substantially encases the first and second pairs of conducting contacts and the identification element and an aperture through which ends of the first and second pairs of conducting contacts extend, a defibrillator socket (3) adapted for connection to a defibrillator and adapted for connection to an electrode plug having a first pair of conducting contacts (24, 26) for connection to the first pair of conducting contacts of the electrode plug, a second pair of conducting contacts (28, 30) for connection to the second pair of conducting contacts of the electrode plug and for connection to the defibrillator, and a housing (32) providing a cavity (34, 36) which substantially encases the first and second pairs of conducting contacts and an aperture through which ends of the first and second pairs of conducting contacts extend, and an electrode identification unit (4) adapted for connection to a defibrillator socket having a circuit comprising contacts for connection to the first pair of conducting contacts of the electrode plug via the first pair of conducting contacts of the defibrillator socket, a signal detector (42) connected to the circuit which detects a signal from the identification element of the electrode plug, and a processor (44) which uses a measure of the signal to determine an identification characteristic of the identification element of the electrode plug and from this identifies a category of the electrode connected to the electrode plug.

    摘要： Dislodgement of a defibrillation lead from the right ventricle to the right atrium is a rare complication associated with implantable cardioverter-defibrillators. However, such dislodgement deserves attention out of proportion to its low incidence because of the possibility to cause fatal proarrhythmia. Various embodiments are directed to algorithms for detecting lead dislodgement, including a primary algorithm that operates during baseline rhythm and a secondary algorithm that operates during detection of ventricular tachycardia or ventricular fibrillation to identify lead dislodgement during atrial fibrillation.
