The Medtronic InSync II Marquis™ cardiac resynchronization and ICD device offers patient-tailored CRT options and effective ICD protection in conjunction with powerful heart failure management and patient safety features.

Key Features

Fast, Effective ICD Therapy Combined with Patient-Tailored Cardiac Resynchronization Therapy

  • 30 Joules high energy output in 5.9 to 7.5 seconds throughout the life of the device.
  • Painless antitachycardia pacing (ATP) therapy to terminate 3 out of 4 episodes of fast ventricular tachycardia (VT).1
  • Enhanced PR Logic dual-chamber detection to maintain high sensitivity for ventricular tachyarrhythmias while improving discrimination for supraventricular tachycardias. Offers 95.2% accuracy (Positive Predictive Value) in delivered therapies.2
  • Separately programmable ventricular outputs for adapting pacing outputs to unique patient needs.
  • Special pacing functions to manage heart failure patients who also experience atrial fibrillation.
  • Programmable with the Medtronic CareLink® Programmer

Powerful Heart Failure Management and Advanced Patient Alert Capabilities

  • Heart Failure Management Report showing 14-month trends of key heart failure patient monitoring categories such as AT/AF Burden, ventricular rate during AF, heart rate variability, patient activity and night/day heart rates. Observation highlight heart failure related parameters outside of typical ranges.
  • Cardiac Compass® Report with additional information about ventricular arrhythmia detection and therapies.
  • Rate Histogram Report provides information about % pacing during episodes of AF, sinus rate profiles and ventricular rate profile during AF.
  • Remote device follow-up with the Medtronic CareLink Network can dramatically reduce the time and resources required for routine device checks. Patients can use the Medtronic CareLink Service to transmit comprehensive device data using a standard phone line while at home, work or while traveling. Within minutes, clinics can view patient device data from any Internet-enabled PC using the secure clinician website. Learn more.
  • Advanced patient alert capabilities, including lead integrity, battery condition change, and ICD therapy issues.
