Cardiac Arrhythmia

An arrhythmia is an abnormal heart rhythm. The term "arrhythmia" refers to any change from the normal sequence of electrical impulses. The electrical impulses may happen too fast, too slowly, or erratically – causing the heart to beat too fast, too slowly, or erratically. When the heart doesn't beat properly, it can't pump blood effectively. When the heart doesn't pump blood effectively, the lungs, brain and all other organs can't work properly and may shut down or be damaged.

There are multiple types of arrhythmia. The most common arrhythmia is atrial fibrillation. Atrial fibrillation affects approximately 3 million Americans today. That number is expected to grow to 12 million by 2050. Risk factors for atrial fibrillation include high blood pressure, heart failure, diabetes, advanced age, hyperthyroidism, and heart disease.

Atrial fibrillation is marked by an irregular heartbeat in the upper chambers of the heart. Sometimes people with atrial fibrillation have no symptoms and their condition is only detectable upon examination by a medical professional. Others may experience one or more of the following symptoms: rapid and irregular heartbeat, fluttering or “thumping” in the chest, dizziness, shortness of breath, weakness, faintness, confusion, fatigue, or sweating. The severity of atrial fibrillation is commonly determined by its duration. Paroxysmal atrial fibrillation is when the heart returns to normal rhythm on its own in less than 48 hours. Persistent atrial fibrillation last longer and sometimes requires medical intervention to restore normal heart rhythm.

 

Indications for Use: The Hansen Medical Sensei® Robotic System and Accessories are intended to facilitate manipulation, positioning and control of Hansen Medical’s robotically steerable catheters for collecting electrophysiological data within the heart atria with electro-anatomic mapping and recording systems, using the following percutaneous mapping catheters: the Polaris-Dx™ Steerable Diagnostic catheters made by Boston Scientific Corporation and the Livewire™ Electrophysiology catheters made by St. Jude Medical.

The safety and effectiveness of this device for use with cardiac ablation catheters, in the treatment of cardiac arrhythmias including atrial fibrillation, have not been established in the United States.
