SONR CRT OPTIMIZATION
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 PLATINIUM 4LV SonR CRT-D 1844 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. PLATINIUM 4LV SonR CRT-D
1844 can also transmit real-time SonR signals via telemetry.
LV MULTIPOINT PACING (MP)
PLATINIUM 4LV SonR CRT-D 1844 features simultaneous multipoint left ventricular pacing
allowing LV pacing on 2 differents vectors at the same time, named MP1 and MP2 LV pacing
sites.
FOLLOW-UP FUNCTION
Storage of memory data:
AIDA (Automatic Interpretation for Diagnosis Assistance) software provides access up to 6
months of patient follow-up with day by day data collection, or up to 24 hours with hourly data
collection. Episodes of ventricular tachyarrhythmia are recorded with one programmable
EGM channel which can be selected, in addition to RV EGM.
Alerts / Warnings:
The device routinely performs security self-checks and technical measurements to ensure
system integrity. When system integrity is found to be at risk outside a follow-up, alerts are
stored in the device memory. When system integrity is found to be at risk during a follow-
up, the information is managed by a warning (pop-up message) to immediately notify the
user. For example, the following types of events can trigger a warning or an alert: technical
problem during a shock, lead impedance or shock continuity measurements out-of-range,
battery depletion, …
REMOTE MONITORING FUNCTION
Remote monitoring enables the automatic remote transmission of implant data to the
physician thanks to the wireless Radio Frequency (RF) communication ability of the implant in
order to provide a comprehensive report to the physician about device functioning and patient
cardiac status without having the patient physically in the clinic.
The data is transmitted from the implant to the SMARTVIEW monitor, a small transmitter
placed in the patient's home.
Implant data are first transmitted to the SMARTVIEW monitor via RF. Data are then routed
through the phone line or via GPRS to an internet website. This website is responsible for
transforming the implant data into a comprehensive report that can be consulted by the
physician.
SMARTVIEW Monitor
The SMARTVIEW monitor is a small device equipped with an RF transmission module to
communicate with the implant and a modem to export data through the internet.
The SMARTVIEW monitor is delivered to the patient who has to install it at home. Preferably
the SMARTVIEW monitor will be placed on the nightstand of the patient, as close as possible
to the side of the bed where the patient usually sleeps. The SMARTVIEW monitor connects
to the phone line of the patient and the power plug. Regular transmissions are done during
