Pioneer of Minimally Invasive Surgeries

We’re leading the way in treatments for arrhythmias like atrial fibrillation. At AdventHealth, we’re the first hospital in Central Florida to offer convergent hybrid ablation, a minimally invasive option for patients with persistent AFib.

Personalized Care To Regain Your Rhythm

AFib Types

A heart rhythm disorder, AFib is the most common type of arrhythmia. It occurs when your heart’s electrical charges malfunction, causing its upper chambers to beat out of sync with its lower chambers.

A few different types of AFib exist:

  • Paroxysmal AFib: short episodes of AFib where the irregular heartbeat resolves on its own within seven days of starting
  • Persistent AFib: AFib that lasts longer than seven days, does not resolve on its own and requires treatment to heal
  • Longstanding AFib: AFib that lasts longer than one year and needs treatment to heal
  • Permanent AFib: AFib that continues indefinitely without treatment
  • Nonvalvular AFib: AFib that’s unrelated to heart valve problems

Regardless of the type, AFib deserves treatment. When your heart beats improperly, it can disrupt your blood flow and increase your risk of stroke, so it’s important to understand what’s causing an irregular heartbeat. Our electrophysiologists will help get you answers and treatment.

AFib Medications


In some cases of atrial fibrillation, medical therapy is the best option. A heart specialist will help you choose the right treatment for you.

Medications used to treat heart rhythm disorders include:

  • Antiarrhythmic medications used to maintain normal heart rhythm or convert the heart rhythm to normal
  • Anticoagulants to thin blood and prevent blood clots
  • Beta blockers to slow the heart rate
  • Calcium channel blockers to slow the heart rate
  • Digoxin to slow the heart rate

Our specialists will help you understand your medication and any potential side effects as part of your tailored treatment plan. Learn more about different medication-based AFib treatment options in our Heart Rhythm Disorders Downloadable Guide.

AFib Procedures and Surgeries

Procedures: Cardiac Ablation and Pacemaker Placement

Cardiac Ablation

When AFib isn’t treatable with medical therapy, ablation is a nonsurgical, wire-based procedure that uses energy to eliminate the cardiac tissue that’s triggering AFib. Cardiac ablation uses radiofrequency or a laser to destroy the abnormal cells so your heart will beat normally. There are several types of ablation techniques, including a new technology called stereotaxis robotic ablation therapy, which is less invasive and uses softer, gentler catheters to resolve your atrial fibrillation.

Medtronic Micra™ Pacemaker

The Medtronic Micra™ Transcatheter Pacing System (TPS) is a tiny, leadless pacemaker that’s less invasive than traditional implants, leaving you free of chest scars and potential medical complications. Unlike most pacemakers, Micra is leadless and implanted directly into the heart — all in one minimally invasive procedure with no chest incision needed. Because Micra is self-contained within the heart, it eliminates possible medical complications arising from a chest incision and from the wires with conventional pacemakers.

Minimally Invasive Surgery: Convergent Hybrid AFib Ablation

Convergent hybrid ablation is an innovative and minimally invasive surgery to treat AFib. In the first part of this two-part procedure, a surgeon will perform a surgical ablation and place an AtriClip device in the heart to close the left atrial appendage, lowering the risk of stroke. The second part of the procedure happens one to two months later, when an electrophysiologist performs a catheter ablation to reinforce the scar tissue created in the previous surgical ablation. The convergent hybrid ablation procedure is a proven and effective option for people who live with persistent AFib that hasn’t improved with medications or other treatments.

Open-Heart Surgery: Maze Procedure

Designed to disrupt the erratic impulse triggers and circuits that cause AFib, Maze procedures create carefully placed scar tissue lesions within the atria to stop faulty electrical impulses from traveling. This creates only one path the electrical impulse can take, which prevents the atrium from fibrillating. The variations of the Maze procedure range from most to least invasive: the Cox-Maze procedure, Modified-Maze procedure and Mini-Maze procedure.

AFib Technology


Our team of skilled electrophysiologists sends electrical signals through a catheter placed in your heart so they can identify any rhythm abnormalities and diagnose your condition. Some of your symptoms may be best treated with a pacemaker or defibrillator. These small devices are implanted into your chest or abdomen to help your heart beat at a normal rhythm.


WATCHMAN provides an alternative to the blood thinner Warfarin for people who need one. This is the only FDA-approved implant proven to reduce stroke risk in people with AFib not caused by a heart valve problem (also referred to as non-valvular AFib). WATCHMAN effectively reduces the risk of stroke without the risk of bleeding that can come with the long-term use of Warfarin.


Stereotaxis is the global leader in innovative robotic-assisted technologies designed to enhance the treatment of arrhythmias and perform endovascular procedures.

The Stereotaxis Niobe® Robotic Magnetic Navigation System consists of two robotically controlled magnets next to the operating table. During a procedure, your physician uses an intuitive computer interface to adjust the magnetic field around you. This allows them to precisely direct and steer a catheter that has a magnet embedded in its tip.

Pacemakers Versus Defibrillators

Pacemakers are typically recommended if you have a slow heartbeat (bradycardia). These devices send electrical impulses to the heart to tell it when to beat. Defibrillators monitor your heart rate and are usually used if your heart beats too fast (tachycardia). The devices have a capacitor that sends a powerful shock to the heart to restore proper rhythm.
