Correct option is C
The correct answer is (c) Heart.
· An ECG (Electrocardiogram) is a test used to measure the electrical activity of the heart. It records the heart's rhythm and electrical signals to detect any abnormalities or conditions such as arrhythmias, heart attacks, and other heart-related issues. The ECG provides a visual representation of the heart’s activity, which helps doctors diagnose and monitor heart conditions.
· An ECG records the electrical impulses that trigger heartbeats and shows them as waves on a monitor or printed paper.
· It is commonly used to detect issues like arrhythmias, myocardial infarction (heart attack), and cardiomyopathy.
Explanation of Other Options:
· Brain: The electrical activity of the brain is examined using an EEG (Electroencephalogram), not an ECG.
· Kidney: The kidney is examined using tests like urinalysis, ultrasound, or CT scans, not an ECG.
· Small Intestine: The small intestine is examined using procedures like endoscopy, not an ECG.
