Cardiac Stress Test

What is a Cardiac Stress Test? How does it work?

A cardiac stress test determines how well the heart is working under physical stress. Typically the test involves walking on a treadmill or riding a stationary bike to monitor the heart’s activity. Exercising makes the heart pump harder and faster, so a cardiac stress test helps reveal issues with blood flow in the heart.

Some reasons a doctor orders a cardiac stress test include:

  • Arrhythmias - heart beats too fast, too slow or irregular
  • Congenital heart disease - defects in the fetus heart
  • Congestive heart failure - heart muscle is weak and can’t pump enough blood to the body
  • Coronary artery disease- narrowing of the coronary arteries caused by the buildup of fatty materials called plaque
  • Heart valve disease- when heart valves become damaged, they can block flow in the heart

Additional/Related Procedures

After an echocardiogram determines the cause of the abnormal heart, a minimally invasive procedure or surgery may be needed to treat it, including:

  • Catheter Ablation: This minimally invasive procedure uses a catheter to apply heat or cold (cryoablation) to disrupt or destroy heart tissue that causes an arrhythmia. It requires a short hospital stay and offers a quick recovery.
  • Implanted Electronic Cardiac Devices: Small battery-powered devices, such as pacemakers, defibrillators and cardiac resynchronization therapy (CRT) devices, are connected to one or more wires (called leads) and are surgically placed under the skin near the collarbone. These devices automatically deliver an electrical signal to control your heartbeat.
  • WATCHMAN™ Left Atrial Appendage Closure: This advanced surgery can significantly reduce the risk of stroke in people with atrial fibrillation by blocking the area in the heart where most stroke-causing blood clots form, called the left atrial appendage.

What to Expect During a Cardiac Stress Test

During a cardiac stress test, a technician will take the patient's heart rate and blood pressure then place electrodes – sticky patches – on the chest, legs, and arms. The wires connect to the machine that records the heart's activity. The patient will walk on a treadmill or ride a stationary bike for about 10 to 15 minutes. As the test goes on, the exercise becomes harder.

Patients are sometimes asked to not eat, drink or smoke before the cardiac stress test takes place.
