Anatomy & Physiology Cardiac #19

Question

Which test does the nurse anticipate for the client who requires monitoring for both the electrical and mechanical functions of the heart?

Answers

  1. Echocardiogram
    • Rationale:

      An echocardiogram tests the action of the cardiac muscle using ultrasound waves to produce a visual display. It is often used for the diagnosis or monitoring of heart disease.

  2. Cardiac stress test
    • Rationale:

      A cardiac stress test measures the heart’s ability to respond to external stress. It is performed in a clinical environment that is controlled.

  3. Electrocardiogram
    • Rationale:

      An electrocardiogram, or EKG/ECG, is a diagnostic test that is used to monitor both the electrical and mechanical functions of the cardiac muscle.

  4. Coronary catheterization
    • Rationale:

      A coronary catheterization is a minimally invasive diagnostic or interventional procedure. A catheter is used to access the coronary circulation and blood filled chambers of the heart.

Overview

New heart tests are always under development to provide a further understanding of disease, injury, and congenital (i.e., present at birth) or acquired abnormalities of the cardiac muscle.

Explanation

Learning Outcomes

While many tests can be used to diagnose heart disease, there are very few that specifically monitor both the electrical and mechanical functions of the cardiac muscle. One such test is the electrocardiogram. This test, abbreviated as EKG or ECG, measures the electrical activity of the heartbeat in addition to the mechanical functions of the heart muscle.
