Deaths contributed by atrial fibrillation per year [2]


Cardiac arrhythmia is one of the leading causes of death in industrial nations. It also causes an increased risk of stroke. Many forms of cardiac arrhythmia can be treated gently with minimally invasive procedures using radiofrequency ablation. In this treatment procedure, a catheter is inserted into the heart to locate the tissue responsible for the arrhythmia. The tissue is then targeted or isolated using radiofrequency current to stop the arrhythmia.

The G4 platform from Stockert is the market-leading solution for cardiac radiofrequency ablation in electrophysiology.
