What are Arrhythmias?

Cardiac Arrhythmias are common medical conditions in which the heart beats irregularly and inefficiently. Electrical signals that flow through the heart regulate each heartbeat. When these signals misfire or travel through the heart in a poor manner, the heartbeat becomes uncoordinated and no longer efficiently pumps blood through the body.

Tens of millions of individuals suffer from arrhythmias. There are different types of arrhythmias and their symptoms and health risks vary. When left untreated, arrhythmias may significantly increase the risk of stroke, heart failure, and sudden cardiac arrest.

The primary therapies prescribed to arrhythmia patients include pharmaceuticals, implanted devices, and cardiac ablation procedures. Cardiac ablation is a well-established treatment for arrhythmias with nearly one million procedures performed each year. This minimally-invasive procedure involves a catheter being navigated through the blood vessels into the heart. The catheter then delivers energy to precise parts of the heart muscle, normalizing the electrical signals and returning the heart to normal healthy rhythm.

Robotic Magnetic Navigation

Robotic Magnetic Navigation (RMN) introduces the benefits of highly sophisticated robotics technology to allow for safer and effective cardiac ablation procedures.1

In traditional cardiac ablation procedures, a physician manually manipulates a catheter by hand. Controlling the catheter tip by holding on to the opposite end (three feet away!) while trying to perform precise movements within the delicate heart isn’t easy. The challenge could be compared to signing your name while holding a long pencil by its eraser.

RMN fundamentally transforms catheter navigation using magnetic fields and robotic precision to navigate a magnetic catheter directly from the tip. The technology consists of two robotically-controlled magnets next to the operating table. During the procedure a physician uses an intuitive computer interface to adjust the magnetic field around the patient. This allows a physician to precisely direct and steer a cardiac ablation catheter that has a magnet embedded in its tip.

The technology may seem like science fiction, but it is very much a reality. Hundreds of physicians at over one hundred leading hospitals globally have used this technology to treat over 100,000 patients to date. The benefits of RMN are well established, with over 300 peer-reviewed scientific publications documenting the benefits of RMN.

Benefits of RMN

Treatment Precision

The precision provided by robotics is incomparable to that available by hand. RMN allows the catheter to reach the exact points where it is needed, wherever that may be. You wouldn’t sign a document holding a pencil from its eraser. Ensure your physician is taking control of the catheter from the tip. Ensure your heart is being treated with great precision and care.


of reported data shows better or equivalent acute and long term procedure success versus manual.¹

Gentle Touch

Your heart is delicate. Manual catheters are rigid – they have to be in order to translate hand movements from the base to the tip. The RMN catheter is guided by the small magnet at its tip and does not require that rigidity. It is soft and gentle, like al dente spaghetti. Ensure your heart is treated safely with a gentle soft touch.


reduction in major complication rates for RMN vs. manual across all reported data.¹

Reduced Radiation

Physicians use x-ray to view the catheter during the procedure. When a physician uses RMN they have all the procedure data presented on a large screen in front of them and are more confident in the safety of the gentler RMN catheter. This confidence leads to much lower usage of x-ray. Another way RMN improves patient safety and care.


of reported data shows a significant reduction in x-ray usage.¹ The average reduction is equivalent to about 235 fewer chest x-rays, compared to manual.²
