Atrium capture verification carefulness bodily organ excited device

摘要

(57) Abstract The atrium of the heart to be captured by atrium excited pulse, high how, the verification possible heart pacemaker. The signal of the atrium is inspected via the electrode which is arranged inside the atrium in the time to after the being spread of the excited pulse from before the being spread of the excited pulse. The signal which is inspected, is analyzed by whether or not in order to be spread into the refractory period between, the P wave generated excited pulse before the being spread of the heart excited pulse detecting. If the P wave is did not generate, inclination of the corrugated signal which is inspected during the specified period which starts from specified time after the excited pulse propagation delay time is decided. If the P wave is detected, the capture state kind of signal which shows non capture state occurs, the P wave is not detected and when it exceeds the specified inclined threshold where the inclination to which the corrugated signal which is inspected is decided is boundary of capture state and non capture state, the capture state kind of signal which shows capture state occurs.
