Cardiology Services 

Managed by Baylor Jack and Jane Hamilton Heart and Vascular Hospital (BHVH), these non-invasive cardiovascular services may be offered to oncology patients:

Non-invasive Cardiovascular Services

  • Exercise stress testing: Assists in identifying electrocardiographic(ECG and EKG) changes during exercise, such as walking on a treadmill or riding a stationary bicycle.
  • Holter monitor: A portable ECG machine that is worn for 1 to 3 days. It constantly monitors a the heart, recording rhythms for physician analysis.
  • Metabolic stress testing: Used to measure the performance of the heart and lungs while the patient is under physical stress, this test involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty while being closely  monitored. A mouthpiece collects and analyzes the air that is breathed in and out.
  • Transthoracic echocardiogram (TTE): Uses high frequency sound waves to create images of cardiac structures and examines the function of the heart. TTE tests are available in the Oncology Outpatient Clinic.
  • Transesophageal echocardiogram: A different approach to an echocardiogram where a specially designed probe is introduced into the esophagus to obtain very clear images of the heart. The patient is under sedation for this procedure.

Non-invasive Vascular Services

  • Venous ultrasound: Involves the use of high-frequency sound waves to produce real-time images of the veins for use in diagnosis and treatment plans.
  • Non-invasive arterial studies and ultrasound: A form of testing in which ultrasound waves measure the speed and direction of blood flow to diagnose blockages.
  • Ankle brachial indexes (ABIs): Blood pressure measurements are taken at the arm and ankle to determine if there is poor blood flow to the leg.
  • Segmental pressures: Similar to ABI, but involves 2 or 3 additional blood pressure cuffs placed just below and above the knee and at the upper thigh. Blood pressure at each point is recorded. Significant drops between body segments may suggest blockages or narrowing in the arteries.
  • Cerebrovascular ultrasound (carotid): Used to view the carotid arteries that lead to the brain, assess for blockage, and monitor treatment of any abnormalities.
