Cardiac Rhythm Disease Management (CRDM) Business Overview

Pioneers in cardiac rhythm technology

In 1957, Medtronic developed the first wearable external cardiac pacemaker, and followed up with the first reliable, long-term implantable pacemaker in 1960.

Today, 50 years later, Medtronic’s Cardiac Rhythm Disease Management (CRDM) division remains a global leader in cardiac rhythm technology. From pacemakers to diagnostics, CRDM’s wide range of products help millions of people with cardiac rhythm diseases and disorders to live longer, better lives.

Pacing Systems

Medtronic, a world leader in pacing technology, designs and manufactures pacemakers to treat patients with bradycardia, an irregularly slow heartbeat.

Defibrillation Systems

Medtronic also produces implantable defibrillators to treat patients with tachyarrhythmia, an irregularly fast heartbeat.

Subcutaneous Diagnostics and Monitoring (SQDM)

The Subcutaneous Diagnostics and Monitoring division of Medtronic provides leading technologies for remotely monitoring cardiac devices, enabling physicians to more effectively care for their patients. We also produce implantable heart monitors, designed to help diagnose cardiac arrhythmias as well as heart-related syncope, transient loss of consciousness or unexplained episodes of fainting.

Electrophysiology Systems

A leading provider of electrophysiology products used for mapping and ablation.

Atrial Therapy business

Atrial Therapy offers treatment of atrial arrhythmias (rapid, uncontrolled heartbeats in the upper chambers) with ventricular tachycardia.

Heart Failure

Heart failure is the inability of the heart to maintain its workload of pumping blood throughout the body, and it accounts for between 5 to 10 percent of all hospital admissions. Medtronic is dedicated to researching the most effective techniques to diagnose and treat patients at risk for heart failure.
