SYNCHRONIZED CARDIOVERSION MIXED MODE OPERATION AND TIMING VERIFICATION

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.

1. A defibrillator, for a synchronized cardioversion mixed mode operation with an external ECG monitor located external to the defibrillator, the defibrillator comprising:
a shock source structurally configured to store electric energy; and a controller including a synchronized cardioversion input channel for receiving a synchronized cardioversion input signal from the external ECG monitor,
wherein the synchronized cardioversion input signal is one of an external ECG waveform of a heart of a patient generated by the external ECG monitor or an external synchronized pulse generated by the external ECG monitor as an indication of a detection by the external ECG monitor of at least one QRS complex of the external ECG waveform, andwherein the controller is structurally configured to control a conditional delivery of a defibrillation shock synchronized with the synchronized cardioversion input signal by the shock source to the patient in response to the controller receiving the synchronized cardioversion input signal as either the external ECG waveform or the external synchronized pulse.
