Nuclear Cardiology Stress Testing

Our cardiac nuclear testing laboratory is accredited by the Intersocietal Accreditation Commission (IAC). This advanced technology is utilized to diagnose various conditions, such as coronary artery disease, and to guide treatment once diagnosed with a heart condition.

Cardiologists, who are experts in interpreting radiologic cardiac studies, will analyze your stress test and cardiac nuclear images and send a signed report to your primary care physician or the physician who referred you for the exam within 24-48 hours. Your physician will discuss the results with you.

Infinity Primary Care’s Diagnostic Testing Center offers a variety of stress tests, including:

  • Exercise stress test (treadmill testing): This monitors blood pressure and heart activity while walking on a treadmill at different levels of intensity, indicating how the heart responds to different levels of exertion and whether any EKG changes occur during exercise.
  • Isotope stress test (nuclear stress test): This uses a radioactive isotope injected intravenously to measure blood flow to the heart during exercise.
  • Pharmaceutical stress testing: This uses medicine rather than exercise to determine if the heart is functioning properly.

 

Preparing for a stress test or cardiac nuclear study
