Pacemaker

Versa Pacemaker

The Versa® Pacing System combines physiologic pacing with automaticity. It’s versatile and automatic.

Overview

Why Is it Critical to Pace Less?

Reducing unnecessary ventricular pacing has been shown to improve clinical outcomes by reducing the risks of atrial fibrillation (AF)1-4 and heart failure hospitalization (HFH)1,4

There is a 1% increase in the risk of AF for each 1% increase in cumulative right ventricular pacing.4


Important Safety Information

Changes in a patient's disease and/or medications may alter the efficacy of a device's programmed parameters or related features.

How It Works

How the Versa Pacing System Works

The new standard of care in pacing is to reduce unnecessary right ventricular pacing to as close to zero as possible. Mounting evidence suggests that right ventricular pacing is associated with a variety of detrimental effects, including risk of heart failure hospitalization and atrial fibrillation.1 The Versa pacing system combines physiologic pacing with automaticity.

Search AV+ Promotes Intrinsic Conduction

  • Search AV®+ (SAV+) automatically and continuously searches for natural intrinsic conduction.
  • SAV+ reduces unnecessary right ventricular pacing to less than 20%*2
  • RV pacing > 40% of the time in DDDR mode was associated with a 2.6-fold increased risk of HFH compared with pacing < 40%.1

Cardiac Compass® Trends

Concise information to:

  • Identify atrial arrhythmias
  • Make key therapy decisions (eg, titrating medications)
  • Monitor results of therapy changes

Assess Rhythm Control*

† The information collected may help with assessment of rate control and risk for stroke in patients with atrial tachyarrhythmias.

Therapeutic Options for AT/AF

Pacing therapies that may help manage tachyarrhythmias and may alleviate symptoms:

  • Atrial Preference Pacing (APP)
  • Post Mode Switch Overdrive Pacing (PMOP)
  • Conducted AF Response
