Cardiac stress testing aims to evaluate how the heart functions under physical exertion or induced stress. Two common methods for this assessment involve electrocardiography combined with imaging techniques. One approach solely uses electrocardiography to monitor the heart’s electrical activity, while the other integrates ultrasound imaging to visualize the heart muscle’s movement during the evaluation. A common example is using either an EKG alone or an EKG with ultrasound during exercise on a treadmill.
These evaluations play a crucial role in identifying coronary artery disease and assessing the severity of existing cardiac conditions. Early detection of ischemia, or reduced blood flow to the heart muscle, can lead to timely interventions and improved patient outcomes. Historically, electrocardiography was the primary method, but the addition of imaging has enhanced diagnostic accuracy, providing more detailed information about cardiac function.
