The Medtronic InSync Marquis™ offers powerful ICD and cardiac resynchronization therapy along with the tools for more efficient heart failure patient management.

Key Features

Powerful ICD and 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
  • Programmable with the Medtronic CareLink® Programmer.

Advanced Monitoring for Changing Patient Conditions

  • Medtronic's exclusive Cardiac Compass® Report with additional information about ventricular arrhythmia detection and therapies.
  • Advanced patient alert capabilities, including lead integrity, battery condition change, and ICD therapy issues.
  • Fast telemetry speed-up to 20x improvement-with RapidRead™ telemetry.
  • Perform tests and record ECGs without attaching separate ECG leads with Leadless™ ECG.
  • 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.
