Question

A client is brought to the emergency department with complaints of chest pain. The physician orders electrocardiography (ECG) to be done. The nurse understands that an ECG helps to accomplish which of the following?

a) Record the heart's electrical pulse
b) Establish size and shape of the heart
c) Evaluate for fluid around the heart
d) Detect myocardial muscle thickness

Answer 1

An electrocardiogram (ECG) helps to record the heart's electrical pulse.

Step-by-step explanation:

An electrocardiogram (ECG) helps to accomplish the recording of the heart's electrical pulse. It is a record of the voltages created by the wave of depolarization and subsequent repolarization in the heart. Using electrodes placed on the chest, the ECG measures the electrical impulses produced by the heart and displays them as a graph of the heart's electrical activity.
