Telemetry Transmission
I was talking with a gentleman planning to move into one of our apartment buildings. He has aCD3231-40Q unit and indicated that it is monitored 24/7 and needs a phone line, although he only has one phone line and can still use it for calls while the monitoring is going on. Do you have some literature on how this transmission works so that I can provide the correct communications for him when it is time to move? Many thanks.Reply

    Downsize Without Compromise
    With the smallest footprint of any CRT-D available, insightful diagnostics and an unprecedented 40 J in delivered energy, the Unify CRT-D is downsized without compromising on energy, longevity, safety or reliability.


  1. The smallest footprint of any high voltage device available for a smaller incision and reduced pocket size
  2. QHR®** chemistry battery provides greater capacity for enhanced longevity and charge times
  3. DF4 connector is designed to simplify implants by streamlining defibrillation connections into a single terminal pin and reducing the number of set screws
  4. Decreased device footprint and volume with the most narrow (40 mm) design available for greater patient comfort and range of motion during activity

  5. Smarter
  6. The addition of antitachycardia pacing (ATP) prior to and while charging in the VF zone further extends the programming options for converting tachyarrhythmias painlessly.
  7. BiVCap®, LVCap™, RVCap® and ACap® Confirm features promote patient safety by automatically ensuring capture of the myocardium in response to pacing stimuli in the left ventricle, right ventricle and right atrium.
  8. The % BiV-Pacing alert notifies clinics when percent biventricular pacing is less than the programmed threshold.
  9. Advanced Biventricular Pacing options:
  10. VectSelect® programmable LV pulse configuration (LV ring-RV coil, LV tip-RV coil or LV bipolar) may be adjusted noninvasively via the programmer.
  11. Triggered Pacing with BiV Trigger Mode helps maintain a high percentage of BiV pacing by triggering pacing in both the left and right ventricles in response to a sensed ventricular event.
  12. Negative AV hysteresis with search promotes ventricular pacing by automatically reducing the AV delay when intrinsic activity is present, thereby promoting a high degree of ventricular pacing.
  13. QuickOpt® timing cycle optimization provides quick and effective optimization for more patients at the push of a button.1
  14. The low frequency attenuation filter is designed to enhance sensing performance and may reduce the possibility of oversensing T waves.
  15. The unique SenseAbility® feature, with Decay Delay and Threshold Start, provides the flexibility to fine-tune sensing to individual patient needs.
  16. Unique AF Suppression™ algorithm is clinically proven to suppress episodes of paroxysmal and persistent AF. Studies show a 25% decrease in symptomatic AF burden.2

  17. Stronger
  18. The unique 40 J Safety Shock provides a greater DFT safety margin and may minimize the need for multiple DFT tests at implant or extra hardware.
  19. DeFT Response® technology tools provide more clinically proven, noninvasive options for managing high DFTs.
