Non-Invasive Cardiology

Non-Invasive CardiologyThe Cardiology Department of the Harden Memorial Heart Program performs thousands of cardiac diagnostic studies each year, using both portable and department-based diagnostic technologies. Cardiology studies are a team effort, each type of study involving specific medical professionals including cardiologists, nurses, technologists and radiologists. Information from these studies help cardiologists diagnose a patient's condition and recommend the most effective course of treatment.

Some of the current studies performed by the Cardiology Department include:

EKG (Electrocardiogram) - These studies record the changes of electrical potential occurring during the heartbeat and produce vital information for diagnosing abnormalities. Studies include Pediatric EKG, Signal-Averaged EKG, Routine Treadmill EKG, and Holter Monitor Studies.

Echocardiography (Echocardiogram) - Utilizing sound waves, these studies produce "moving pictures" of the heart. The newest technology allows us to make two-dimensional images. The types of echo studies we conduct include:

  • Two-Dimensional
  • M-Mode
  • Pulsed Wave, Continuous Wave and Color Flow Doppler
  • Transesophageal Echo: Biplane and Multiplane
  • Exercise Stress Echo
  • Doubtamine Stress Echo (Pharmacological Stress Echo)

Tilt Table Testing - A study designed to understand fainting episodes.

Stress Tests - These tests show us how a patient's heart responds to an increased heart rate. Types of stress tests include:

  • Exercise Myocardial Perfusion Stress Test - A radioactive isotope that illuminates the vessels is injected and the patient walks on a treadmill to achieve a target heart rate. Scans taken before and after show changes in the heart's activity.
  • Dobutamine Myocardial Perfusion Stress Test and Persantine Myocardial Perfusion Stress Test - In this test, drugs, rather than a treadmill, are used to achieve increased heart rate.
