Description
なお、一般にPVCの定義は、通常DDDモードやVDDモードの場合、心房側にリードが挿入されているが、心室イベントの前に心房イベントのセンシング或いはペーシングイベントが無い場合にはPVCであるとしている。
Claims (5)
- トリガーペーシング機能および心房性不整脈状態を検知する機能(以下、心房性不整脈検知機能)を備えた心不全(HF)治療用デバイスにおいて、前記心房性不整脈検知機能により患者が心房性不整脈状態であると判断された場合であっても、前記トリガーペーシング機能はセンシングされる心室の全てのイベント対して中止(抑制)されない機能(以下、トリガーペーシング機能A)を備えたものであることを特徴とする心不全(HF)治療用デバイス。
