16.6. SONR CRT OPTIMISATION
SonR is a specific sensor, located at the tip of the atrial lead, that
picks-up micro-accelerations of the heart walls to derive information
pertaining to cardiac contractility. The signal picked-up by the SonR
sensor can be processed by PARADYM RF SonR CRT-D 9770 in
order to automatically adjust VV delays and AV delays during rest
and exercise for optimal resynchronization therapy. In addition, the
SonR signal is recorded during tachyarrhythmia episodes to depict
acute variations of cardiac contractility. PARADYM RF SonR CRT-D
9770 can also transmit real-time SonR signals via telemetry.
