What does ECG stand for?
Answer: Electrocardiogram
An ECG is a test that measures the electrical activity of the heart to detect abnormalities.
What is the primary purpose of an ECG?
Answer: To record electrical signals in the heart
ECGs detect electrical activity to assess heart health and diagnose issues like arrhythmias or ischemia.
What do the P wave, QRS complex, and T wave represent in an ECG?
Answer: Electrical activity during different phases of the heartbeat
The P wave shows atrial depolarization, the QRS complex indicates ventricular depolarization, and the T wave reflects ventricular repolarization.
Which of the following is the normal heart rate range shown in an ECG?
Answer: 60–100 bpm
A normal resting heart rate for adults typically falls within this range.
What does a prolonged QT interval indicate?
Answer: Increased risk of arrhythmias
A prolonged QT interval can signify an electrical imbalance, increasing the risk of life-threatening arrhythmias.
