The Medtronic AF advantages across our portfolio

  • Increase the accurate and timely diagnosis of AF.1
  • Improve AF patient outcomes.2-5
  • May reduce AF-related utilization of healthcare resources.3,6
  • Use the LINQ™ family of ICMs (Reveal LINQ™ ICM and LINQ II™ ICM) to make data-guided management decisions such as medical management, including anticoagulation.7-10

Detect AF

Timely and accurate AF detection and monitoring through device-based algorithms.

LINQ family of ICMs 

LINQ ICMs provide data that enables clinicians to objectively diagnose and monitor both asymptomatic and symptomatic AF.11

This data results in the measure of true AF burden and enables data-driven decisions, including those related to medications and treatments such as anticoagulants or ablation.7-10

Cobalt™ XT VR ICD
Cobalt™ VR ICD

Using the TruAF detection algorithm, Medtronic single chamber ICDs are the only ICDs that can detect AF with a traditional lead.

  • 34% of patients had AF detected at six months.15

Watch as Dr. Alan Cheng discusses the importance of AF detection in a single chamber ICD.

Reduce AF

Exclusive algorithms demonstrated to reduce the risk and duration of AF.

Managed Ventricular Pacing (MVP™)

Reduces unnecessary RV pacing by 99%.16

  • Every 1% of unnecessary RV pacing is accompanied by a 1% greater AF risk17

Reactive ATP™ algorithm

Reduces the duration of AT/AF.18

  • ≥ 1 day by 19%
  • ≥ 7 days by 36%
  • ≥ 30 days by 44%

AdaptivCRT™ algorithm

46% reduction in AF risk.19

The Reactive ATP (rATP) algorithm delivers atrial antitachycardia pacing (ATP) to terminate an ongoing AF episode after a programmed interval, or when the rhythm organizes and/or slows. Recent evidence shows rATP reduces the likelihood of patients experiencing AT/AF.18 Learn more in this informative video as CRHF Chief Medical Officer, Dr. Rob Kowal, discusses the data.

Nearly 20 years of research and physician collaboration resulted in cardiac device algorithm innovations that help manage AF.

Watch Dr. Amin Al-Ahmad walk through this history and discuss the AdaptivCRT algorithm, which reduces AF risk,19 and the Reactive ATP algorithm, which reduces AF duration.18

Respond to AF

Exclusive feature to improve effective CRT delivery in the presence of AF.

EffectivCRT™ during AF algorithm

Up to 16% increase in effective CRT delivery20

The AdaptivCRT algorithm optimizes CRT pacing every minute whether AV conduction is normal, prolonged, or blocked. The EffectivCRT during AF algorithm automatically changes the pacing rate to increase effective CRT delivery during AF by up to 16%.20

Dive deeper with Ruth Klepfer, senior research manager, as she explains how these two CRT algorithms work together to help manage AF in this short video.

Treat AF

Restore life's rhythm by unlocking potential through novel and efficient technology built on unmatched experience​. 

Arctic Front™ family of cryoballoons

The only catheters approved for initial rhythm control treatment as an alternative to anti-arrhythmic medications.21

A safe and effective tool for early rhythm control that has been used to treat over one million patients worldwide.22

The Arctic Front family of cryoballoons has proven shorter, more predictable procedure times, enabling the lab to benefit from less overtime, block schedule consistency,23,24 increased staff satisfaction,25 and more.

DiamondTemp™ ablation system

The only open-irrigated RF catheter with industrial diamonds to optimize power based on direct tissue surface temperature measurement. DiamondTemp is a safe and effective tool to treat AF patients.

Compared to contact force-RF, the DiamondTemp ablation system demonstrated26:

  • 40% reduction in RF time
  • 55% reduction in individual RF ablation duration
  • 58% reduction in saline infusion

Long-term cardiac monitoring

Continued cardiac monitoring after an AF ablation with the Medtronic LINQ family of ICMs provides comprehensive data including AF burden, activity level, and heart rate variability. This data may be used by physicians to guide AF management decisions, including the use of anticoagulation.7-10 Insertable cardiac monitors remain the gold standard for the detection of AF recurrence and quantification of AF burden.*27

*Compared to intermittent monitoring.
