A cardiac electrotherapy device comprises an elongated elastic lead body (10, 11) having a distal electrode (14, 15) adapted to be connected to the heart; said lead body, including a sensor portion (17, 18) at a location adapted to undergo deformations responsive to heart muscles contractions, when the lead body is connected to the heart; said lead body comprising a high frequency transmission line means, having two conductors which are provided with terminals at the proximal end of the lead and which are adapted to transmit high frequency signals from the terminals to the sensor portion of the lead and vice versa; said sensor portion is varying its high frequency electric parameters, when being subjected to said deformations. |
