ECG
-
D.
ECT
Correct Answer:
C. ECG
Explanation:
An electrocardiogram (ECG or EKG) is the primary diagnostic tool used to identify heart problems by recording the heart's electrical activity. During the procedure, electrodes are placed on the skin to detect the tiny electrical impulses produced with every heartbeat. These signals are translated into a graph that allows healthcare providers to analyze heart rate, rhythm, and structural changes. It is a quick, noninvasive, and painless test used to diagnose conditions such as heart attacks, arrhythmias, and coronary artery disease. While other options like BCG (a tuberculosis vaccine), EEG (a brain activity test), and ECT (a psychiatric treatment) involve medical monitoring, only the ECG is specifically designed to evaluate cardiac function.
