Cardiology is the medical treatment of diseases of the heart and parts of the circulatory system. Cardiologists are the doctors who specialize in diagnosing and treating these conditions.

Complete cardiovascular care at our Heart Center

Our Heart Center is one of the largest dedicated cardiac centers in Jacksonville, with over 10,000 patients treated annually. It is located on the north end of the hospital and has its own entrance, valet parking and waiting room.

Our cardiovascular care program

Together, our specialists work with you to deliver truly comprehensive heart care, from prevention and diagnosis to treatment and recovery. Cardiology services offered at our hospital include clinical research trials, minimally invasive heart and vascular surgery and cardiac rehabilitation. We also have a dedicated cardiac intensive care unit (ICU) with a team focused on treating patients with critical heart conditions.

Our other services include:

Heart imaging

We provide advanced heart testing and imaging to detect the cause of the problems you may be experiencing. We offer positron emission tomography (PET) and computerized tomography (CT) scans as well as echocardiograms.

Cardiac catheterization (cath) lab

To further examine your heart's function, your doctor may recommend cardiac catheterization. During this minimally invasive procedure, a long, thin tube (catheter) is inserted into a vein and threaded to your heart. It can be used to:

  • Determine the amount of oxygen in the heart
  • Diagnose heart defects
  • Identify problems related to the heart valves
  • Locate blockages in the blood vessels
  • Perform a tissue biopsy in the heart
  • Test pressure

Cardiac catheterization is also used in the following procedures performed to treat heart disease:

  • Ablation for heart arrhythmia
  • Angioplasty, with or without a stent placement
  • Closure of holes in the heart, including patent foramen ovale (PFO)
  • Heart valve repair or replacement
  • Thrombectomy for blood clots

What to expect during cardiac catheterization

Cardiac catheterization is generally performed under local anesthesia. A dye is injected into a small tube so the cardiologist can get a clear view of the affected area. Recovery time from a cardiac catheterization procedure is quick, and there is a relatively low risk for complications.

Electrophysiology (EP) lab

If you are experiencing heart rhythm problems, our electrophysiology lab can help diagnose arrhythmias and determine the best care plan for you. We offer a range of diagnostic services and treatment options to meet your needs.

Electrocardiogram (ECG or EKG)

An EKG or ECG is a test that checks for problems with the heart’s electrical activity. This test is performed to:

  • Check the health of the heart when other diseases or conditions are present, such as high blood pressure, high cholesterol, cigarette smoking, diabetes or a family history of early heart disease
  • Check the heart’s electrical activity
  • Check the thickness of the heart chamber wall
  • Determine if medicines are working and if they are causing certain side effects
  • Determine the cause of certain heart disease symptoms, such as unexplained chest pain, shortness of breath, dizziness, fainting or rapid/irregular heartbeats
  • Determine the cause of unexplained chest pain, such as a heart attack, inflammation of the sac surrounding the heart (pericarditis) or reduced blood flow to the heart muscle (ischemia)
  • Determine the effectiveness of pacemakers or implantable cardioverter defibrillators (ICDs)

Stress test

An exercise EKG tests for changes in your heart while you exercise. Your physician may order this test to check any abnormalities that can be seen in the EKG only during exercise or while symptoms are present. This test is sometimes called a “stress test” or “treadmill test.”

A resting EKG is always done before an exercise EKG test, and the results of both tests are compared. A resting EKG is performed first because it may show a heart problem that would make an exercise EKG unsafe.

Atrial fibrillation (A-Fib) treatment

According to the Center for Disease Control and Prevention (CDC), A-Fib is the most common type of irregular heart rhythm. It occurs when the upper chambers of the heartbeat irregularly and cause the lower chambers of the heart to pump blood abnormally and ineffectively. Over time, A-Fib may become more frequent and longer lasting, sometimes leading to chronic or permanent A-Fib. It can also increase your risk of stroke.

We use a multidisciplinary approach to determine the best A-Fib treatment options for you. Your treatment may include:

  • Cardioversion
  • Catheter ablation
  • Cryoablation
  • Hybrid maze procedure (includes surgical and catheter ablation)
  • Implantable cardioverter defibrillator (ICD)
  • Left atrial appendage closure (LAAC) implant
  • Medication
  • Pacemaker implant
  • Radiofrequency ablation

To learn more about the services offered by our A-Fib clinic, please call (904) 702-2342.

Heart attack treatment

If you are experiencing a heart attack, it's important to act quickly and seek emergency care right away. Our emergency room is equipped to provide comprehensive and fast treatment for heart attacks.

Signs of a heart attack include:

  • Chest discomfort (including pressure, pain, tightness or aching sensation in your chest or arms)
  • Cold sweat
  • Fatigue
  • Lightheadedness
  • Nausea, indigestion or abdominal pain
  • Pain or discomfort in one or both arms, the neck, jaw, back or stomach
  • Shortness of breath

If you or someone you know is experiencing the signs of a heart attack, call 911 immediately.

Memorial Valve Clinic

At our Memorial Valve Clinic, we have experienced medical staff trained in the detection and treatment of valve conditions. Our affiliated cardiologists and cardiothoracic surgeons work as a team to provide the care you need.

Initial evaluation

When you come to our valve clinic, we will work with you to get a complete understanding of your health history and any symptoms you may be experiencing. Your initial evaluation will include:

  • A comprehensive review of your medical history
  • A physical examination
  • An echocardiogram
  • A discussion of test results and treatment plan options

Signs of heart valve disease

The heart depends on four tiny valves to help blood flow properly and deliver oxygen throughout the body. However, heart valve disease can occur if one or more of the heart valves isn't working properly.

Signs of heart valve disease include:

  • Chest pain and pressure or a feeling of squeezing or heaviness
  • Fainting or dizziness
  • Heart murmur detected by your physician
  • Shortness of breath or breathing too hard
  • Swelling of the legs

Some of these may also be symptoms of a heart attack or other serious medical condition. If you are experiencing these or other symptoms of a heart attack, call 911.

Heart valve disease treatment

Treatment for heart valve disease depends on the severity of symptoms and how well the heart is functioning. For many patients, we treat heart valve disease with medications and close observation. For others, we may recommend valve surgery.

In addition to aortic valve replacement, we offer:

Mitral valve repair

Mitral valve replacement can be used to treat individuals with aortic stenosis or a leaky mitral valve. Compared to valve replacement, mitral valve repair provides better preservation of heart function and a lower risk of complications. It also eliminates the need for long-term use of blood thinners.


TAVR can help patients with severe aortic stenosis feel better and live longer. It is the only valve replacement option for patients with severe aortic stenosis who do not qualify for traditional surgery.

TAVR is a minimally invasive procedure using a catheter to replace the aortic valve without requiring open heart surgery.

The benefits of TAVR can include:

  • Faster return to normal activities
  • Fewer days in the ICU
  • Less blood loss compared to conventional open heart surgery
  • Shorter hospital stay
