SOPHÒS 151

Dual chamber pacemaker based on an efficient microprocessor technology. Sophòs 151 is characterized by an accelerometric sensor for rate modulation according to patient’s chronotropic needs, and by an hemodynamic sensor based on Trans Valvular Impedance (TVI).
Such characteristics, with a wide range of programmable parameters and functions, allow an effective optimization of therapy for each patient.

Special Functions
• Advanced management of frequencies
• Advanced management of AV Delay
• Protection functions on tachycardia or ectopic events
• Ejection check after ventricular pacing (diagnostic)
• Ejection check after ventricular sensing (diagnostic)

Rate Responsive System
The Rate Responsive system is based on a sophisticated accelerometric sensor.
The system allows to program the rate responsive curve in a extremely flexible way.
Furthermore, the presence of 4 rate responsive predefined profiles for different patient’s life style and an automatic procedure of calibration make easier and faster activation and adjustment.

TVI Sensor
The TVI signal (Trans Valvular Impedance) is measured between right atrium and right ventricle.
The possibility to choose the electrodic configuration to measure signal and the auto-calibration current system in order for such detection, allow to obtain an optimal signal in every implant, also in those cases of elective pacemaker substitution.
The sensor detects, cycle by cycle, the effective mechanical heart contraction, allowing to realize the functions of permanent ventricular ejection check (ejection check after ventricular pacing) and protection in case of oversensing (ejection check after ventricular sensing).
Furthermore, it’s possible to obtain an hemodynamic monitoring of the patient, thank’s to the long term storage capacity: in case of decay of hemodynamic performance an appropriate warning will be visible to the user on the programmer’s screen.

Diagnostic
A wide diagnostic section, managed easily by programmer, allows to obtain all necessary information for an optimal pacemaker operation according to patient’s requirements.
