Accurate Therapies
How can you reduce the use of shock therapy, without prolonging time to arrhythmia termination? With PARAD+, that's how.

  • Inappropriate shocks are linked to anxiety and depression and continue to be a major source of distress to patients5
  • A Fib is the primary cause of inappropriate shocks5 (A Fib prevalence in HF patients: 20-30%4)
  • ATP for fast VT is highly effective and prevents painful shocks3, but can increase time to arrhythmia termination or cause unnecessary charges

Superior Specificity
PARAD+TM is an enhancement of PARADTM, which has been shown to have the best arrhythmia classification1. PARAD+TM provides superior arrhythmia discrimination (94% specificity). Minimizing inappropriate shocks2.

FVT Stability Analysis

  • No inappropriate ATP
  • No delay in case of VF

Safe and Painless3

  • Antitachycardia pacing is programmable in three VT zones, slow VT, VT, and fast VT for painless therapy
  • Autoswitch ATP: The last successful ATP therapy is applied as a priority
  • Unnecessary charges are avoided when ATP is effective
  • Fast VTs stability is analyzed allowing the selection of ATP or shock therapy

3. ”Empirical ATP is highly effective in treating FVT. It prevents painful shocks without any clinical difference in episode duration, arrhythmic syncope, acceleration, or sudden death while yielding improvement in QoL. The investigators of the PainFREE Rx II trial recommend ATP as the preferred therapy for FVT in most ICD patients.” Mark S.
