Heart screening and imaging tests we offer

Our cardiologists and heart specialists are committed to delivering the care that results in your best heart health. We provide the most effective treatments to resolve heart abnormalities, disorders or diseases. Heart imaging and screening tests help our heart doctors diagnose specific heart conditions to then develop customized treatment plans for you.

Some of these diagnostic heart screening tests include:


This test uses sound waves to take moving pictures of the heart. It is used to assess the pumping function of the heart and will show the doctor if there is heart disease or problems with the heart valves.

Electrocardiogram (EKG or ECG)

This test records the heart’s electrical activity.

Holter monitoring

This test records how your heart reacts during rest and activity over a 24 to 48 hour period. During this time, you wear a small, portable tape recorder with electrodes attached to your skin.

Nuclear medicine

This test evaluates the cause of some of your symptoms, such as chest pain and/or shortness of breath.

Stress test

An exercise stress test or treadmill test is done to examine the heart’s ability to function under physical stress and exercise. The results help diagnose heart disease and causes of chest pain and coronary artery disease.

Electrophysiology study (EPS)

An EPS is used to diagnose the cause of heart arrhythmias, or abnormal heartbeats. EPS are also used to identify where arrhythmias are occurring and what treatment option is needed.

A catheter is inserted into your artery and guided to your heart. During this process, electrical pulses are sent through the catheter to trigger your heart to beat at different speeds.

Your doctor is able to watch the video monitor during the procedure and trace the signals produced to the source of the arrhythmias, allowing your doctor to identify the cause and location of the irregular heartbeat.

Cardiac catheterization

During cardiac catheterization, a thin, flexible tube called a catheter is inserted in to an artery and then guided through to your heart. A contrast color dye is injected into the catheter so it will show up easier on the X-ray monitors, highlighting any blockages or other blood flow issues needing attention.

The results of your cardiac catheterization may indicate you have a narrowed artery, which may be opened by angioplasty and/or stenting.

Our cardiologists use this nonsurgical diagnostic procedure to:

  • Diagnose heart conditions or diseases
  • Detect blockages of blood flow to and from the heart
  • Check for heart defects
  • Assess the functioning of the heart valves and chambers
  • Evaluate an enlarged heart
  • Measure pressures within the heart
  • Develop a personalized treatment plan

Advanced heart monitoring

Largo Medical was the first hospital in the Tampa Bay area to perform the implantation of this special, wireless heart failure sensor. It allows physicians to monitor patients with heart failure while the patients are at home.

This miniature sensor is implanted in the pulmonary artery (PA) during a minimally invasive procedure to directly measure PA pressure. The system allows patients to transmit PA pressure data from their homes to their healthcare providers. This allows for personalized and proactive management to reduce the likelihood of hospitalization.
