Cardiac Services


The diagnostic heart care we provide at Mercy Medical Center is mostly non-invasive, which means the procedures do not break the skin.


Cardiac Diagnostic Services

  • Electrocardiogram—checks for problems with the electrical activity of your heart.
  • Patent ductus arteriosus (PDA) diagnostics - used to diagnose whether or not there’s an opening between the two major blood vessels leading from the heart.
  • Transthoracic Echocardiogram—a type of ultrasound to evaluate how your heart muscle and valves are working.
  • Treadmill testing/other stress tests—monitors how your heart functions while exercising or under exertion.
  • Nuclear medication scan—identifies damaged heart muscle, shows how blood flows to the heart, and how the heart pumps blood out to your body.
Cardiac Catheterization Lab

Cardiac catheterization is a diagnostic and therapeutic procedure that allows doctors to study the heart and surrounding blood vessels. One or more thin, flexible tubes are inserted through a blood vessel in the arm or leg to record blood flow, calculate cardiac output, and evaluate the heart’s electrical activity.

Cardiac Catheterization Lab Procedures

  • Angioplasty/Stenting
  • Cardiac Nuclear Scans
  • CT Heart Scan
  • Echocardiogram
  • Electrocardiogram
  • Heart MRI
  • Stress Test
  • Tilt Table
  • 24-hour EKG recording
  • Stress Echocardiogram

Complex Procedures

  • Biopsies and draining fluid build-up around the heart
  • Vascular procedures in the arteries and veins of the arms and legs (we use carbon dioxide instead of dye for peripheral vascular procedures, thus protecting the kidneys)
  • Electrophysiology studies to detect and treat heart rhythm disorders and atrial fibrillation, plus implantation of pacemakers and AICDs (implantable defibrillators)

Cardiac Rehabilitation

Cardiac Rehabilitation is a program of heart specific exercise and education that is designed to assist you in resuming a healthy lifestyle.
