Description
例えば、ペーシングの場合、療法モジュール44は、例えば、電極28a、28b及びリング電極30a、30bを使用する、双極電極の設計を介してペーシングパルスを送り出すことができる。その他の場合、療法モジュール44は、例えば、電極28a、28及びIMD22のハウジング電極を使用する単極電極の設計を介してペーシングパルスを送り出すことができる。療法モジュール44は、スイッチモジュール(図示せず、且つ検知モジュール42に関して上述したものと同一又は異なるスイッチモジュールとすることができる)を含むことができる。制御モジュール40は、刺激療法を送り出すため、利用可能な電極のどれを使用すべきかを選ぶスイッチモジュールの設計としてもよい。療法モジュール44は、正弦波、方形波又はその他の実質的に連続的な信号のような、パルス又はショック以外の他の信号の形態にてこれら型式の刺激の1つ又はより多くを送り出すようにしてもよい。
