Personalized Care to Regain Your Heart's Rhythm

Did you know that even subtle symptoms like a simple fluttering or skipping sensation can be signs of an irregular heartbeat or arrhythmia, like AFib? While often harmless, this can lead to serious concerns like heart failure or stroke. We’re here to help with all the information, resources and support you need to make smart, proactive decisions about your health.

At the AdventHealth Heart, Lung and Vascular Institute, you’ll find an extensive program for people with AFib and other heart arrhythmias. Our cardiac experts are pioneers in minimally invasive treatment options like Micra™, the world’s smallest pacemaker, and the WATCHMAN™ FLX device, and also perform advanced atrial fibrillation surgeries like ablation and hybrid ablation. Doctors throughout the Southeast refer their most complex cases to us, where we provide world-class care close to home throughout Central Florida.

Your Treatment Is Our Specialty

We know you have a life to live, and that you don’t want to spend any more of it than you have to in the hospital. At the AdventHealth Heart, Lung and Vascular Institute, we treat arrhythmias and atrial fibrillation using some of the latest technologies and procedures, including minimally invasive surgeries, so you can get back to the life you love.

  • Electrophysiology Studies

    Our electrophysiology team skillfully diagnoses heart rhythm abnormalities and treats patients with leading-edge therapies, including pacemakers and other implanted devices.

  • Common Procedures

    Cardiac ablation is a procedure used to destroy small areas of tissue in your heart that may be causing your heart rhythm problems. This is most often performed with a minimally invasive approach using a catheter inserted through a tiny incision in your groin.

  • Pacemaker

    A pacemaker is a small device placed in the chest or abdomen to help control abnormal heart rhythms. We’re proud to be the first in Orlando to offer the minimally invasive Micra™ headless pacemaker, which is just one-tenth the size of a traditional implant.

  • Minimally Invasive Surgery

    Our expert cardiac phvsicians continue to stav at the forefront of treatment options to cure chronic AFib. We offer minimally invasive surgeries like the convergent procedure, which combines minimally invasive heart surgery and traditional catheter ablation to treat persistent atrial fibrillation.
