Cardiac Testing

New and advanced diagnostic heart tests and tools are constantly being introduced to further understand the complexity of heart disease, injury and congenital or acquired abnormalities. UnityPoint Health – Keokuk provides the following testing that help further the understanding and identifying cardiovascular diseases:

Electrocardiogram (EKG)

EKG is a painless, noninvasive way to diagnose many common types of heart problems. A EKG may be used to detect:

  • Arrhythmias
  • Heart defects
  • Blocked or narrowed arteries (coronary artery disease)
  • Problems with heart valves
  • Heart attacks
  • Previous heart attacks

Exercise Stress Test or Treadmill Test

An exercise stress test is used to gather information about who well the heart works during physical activity. 

Exercise Myocardial Perfusion Scan

A nuclear scan given while the patient is exercising that may reveal areas of the heart muscle that are not getting enough blood.

Adenosine Myocardial Perfusion Scan

A nuclear scan given to a patient who is unable to exercise to reveal areas of the heart muscle that are not getting enough blood.

Holter Monitor

A small, wearable deice that records heart rhythm.

Event Recorder

Similar to the holter monitor, this device is worn during normal daily activities for a longer period of time to record heart rhythm.

Tilt Table Test

This test is to determine if the patient is prone to sudden drops in blood pressure or slow pulse rates.
