evaluate heart mechanical activity through cyclic fluctuation detection of Trans-Valvular Impedance signal.<\/p>\n<p>Both have an accelerometric sensor for rate modulation according to patient\u2019s chronotropic needs.<\/p>\n<p>Such characteristics, with a wide range of programmable parameters and functions, allow an effective optimization of therapy for each patient.<\/p>\n<p>Main functions implemented in this models:<\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>Ejection check after ventricular pacing algorithm with energy trend of ventricular impulse variation.<\/li>\n<li>Ejection check after ventricular sensing, protection in case of oversensing.<\/li>\n<li>Adaptive AV Delay with hysteresis function.<\/li>\n<li>Rate Hysteresis with intrinsic rate search.<\/li>\n<li>Accelerometric sensor with individual optimization and post-exercise adjustment.<\/li>\n<li>Unexpected intrinsic rate decrease control.<\/li>\n<li>Adjustment to rest and circadian rhythm.<\/li>\n<li>Quick response to PAC.<\/li>\n<li>Reversible mode conversion.<\/li>\n<li>Watchful atrial pacing.<\/li>\n<li>Anti PMT.<\/li>\n<li>Long-term hemodynamic evaluation thanks to TVI signal.<\/li>\n<li>Stimulation protocols with burst and extra-stimuli.<\/li>\n<li>Expected life with 100% pacing immediately available after pacemaker interrogation.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Moreover, Soph\u00f2s 355:<\/h3>\n<p>&nbsp;<\/p>\n<ul>\n<li>Automatic implant and lead polarity recognition.<\/li>\n<li>Automatic lead polarity switch.<\/li>\n<li>Energy trend of ventricular impulse variation .<\/li>\n<li>Estimated PM life obtained by diagnostic data.<\/li>\n<li>Lead impedance measure out of follow up.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Trans-Valvular Impedance TVI<\/h3>\n<p>TVI signal (Trans-Valvular Impedance) is measured between right atrium and right ventricle.<\/p>\n<p>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.<\/p>\n<p>The sensor detects, cycle by cycle, the effective mechanical heart contraction, allowing to realize the functions of permanent ventricular ejection check with automatic adjustment of pacing energy in case of loss of capture (ejection check after ventricular pacing) and protection in case of oversensing with an automatic safety pacing in case of external interferences (ejection check after ventricular sensing).<\/p>\n<p>Moreover, it\u2019s possible to obtain an hemodynamic monitoring of the patient, thanks 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\u2019s screen.<\/p>\n<p>&nbsp;<\/p>\n<h3>Diagnostic<\/h3>\n<p style=\"text-align: left;\">Long-term monitoring of ventricular mechanics: TVI sensing provides the opportunity to monitor the mechanical performance of the hearth in acute conditions as well as in the long-term.<\/p>\n<p style=\"text-align: left;\">A wide diagnostic section, managed easily by programmer, allows to obtain all necessary information for an optimal pacemaker operation according to patient\u2019s requirements.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p align=\"left\"><img
