World-Class Cardiac Arrhythmia Management 

Confronting the burden of cardiac arrhythmias

The global burden of cardiac arrhythmias is staggering. Patients with atrial tachycardias (ATs) and atrial fibrillation (AF) face an increased risk for stroke, dementia, heart failure and death,1 and the number of patients with AF is expected to double in the next 40 years.2 Ventricular tachycardia (VT) and ventricular fibrillation (VF) are even more serious. Sustained VT is fatal. Analysts estimate that annually almost 4 million people experience sudden cardiac death worldwide, with about half of those deaths attributed to VT.3

We are recognized as an industry leader in arrhythmia management. Our electrophysiology (EP) and cardiac rhythm management (CRM) solutions can help you and your patients manage a range of cardiac arrhythmias, from the most common to the most dangerous.

Innovative Technology to Improve Quality of Life and Reduce Mortality Rates

At St. Jude Medical, we remain committed to developing effective, innovative technologies that help you treat and monitor AT and AF as well as VT and VF. Like you, we want to see permanent relief for patients all over the world who suffer from cardiac arrhythmias. In 2005, St. Jude Medical dedicated an entire business unit to creating curative therapies for the treatment of AF. Since that time, we have consistently invested 12 to 13 percent of our total revenue toward the research and development of cutting-edge technologies and clinical advancements across all therapy areas.  

We invest resources in transforming health care, and our investments have brought these advances: 

  • Contact force ablation to monitor the force applied at each ablation location and potentially avoid risks related to the application of too little or too much force6-8
  • Enabled navigation of devices on prerecorded X-ray images for reduced duration of live X-ray11
  • Improved navigation accuracy through catheter tracking with MediGuide™ Technology, our sensor-based electromagnetic navigation system12
Infographic states 46.1 million people worldwide have AF (0.5% of the world

Transforming the Treatment of Cardiac Arrhythmias

Our vision is to transform the treatment of cardiac arrhythmias and other expensive epidemic diseases by creating innovative, cost-effective technologies that are effective for healthcare professionals and patients alike. We back our innovation with clinical leadership by building a body of evidence that proves the safety, efficacy and cost-effectiveness of our transformative therapies.

See clinical studies

Cardiovascular diseases (CVDs) are the No. 1 cause of death globally, accounting for 30% of all deaths worldwide.9

Remote Monitoring Potential Benefits

Advancing Cost-Effective Therapies

Cardiac arrhythmias impact millions of adults worldwide, and experts expect that number to increase dramatically.2 In order to combat the growing prevalence of and rising costs associated with cardiac arrhythmias, we focus on developing technologies that will improve patient quality of care and decrease the substantial economic burden that comes with hospitalization and treatment. 

In order to address the rising costs of cardiac arrhythmias, we have designed the products in our cardiac arrhythmia management portfolios to:

  • Reduce ablation procedure time with the TactiCath™ Quartz contact force ablation catheter13
  • Reduce duration of fluoroscopy time* with MediGuide™ Technology11
  • Reduce the number of hospital admissions as a result of remote monitoring14
  • Reduce the frequency of patient visits and in-person follow-ups as a result of remote monitoring15
  • Reduce patient length of stay per hospitalization as a result of remote monitoring15
  • Improve clinical and lab workflow and efficiency with products in our integrated lab portfolio16
Infographic states by 2030 medical costs for CVD will triple from $263 billion to $818 billion
