The system and the method of detecting the atrium event of the heart making use of only atrium inspection

摘要

(57) Abstract When the atrium needs electric removal small motion, the atrial fibrillation removal vessel which includes the continual monitoring system which includes the electric removal small motive which impresses electric removal small electrodynamic air energy to the atrium of the heart, makes detection the atrium arrhythmic detector start. The monitoring system the inspection amplifier (51) and includes with the A wave detector (53) which inspects the atrium activity of the heart detects the A wave of the heart. The 2nd threshold where the A wave detector, with 1st threshold and is higher than 1st threshold and selects it possesses. The threshold selecting arrangement responding to the A wave which each one is detected, just the limited time period which starts delay time period after the A wave which each one it detects activates 2nd threshold. The A wave detector offers the indication of the A wave which each one is detected, the atrium arrhythmic detector (70), when A wave detection rate exceeds the specified limit, is operated.
