MCQ on ECG

An electrocardiogram (ECG) is a simple test that checks the rhythm and electrical activity of your heart. The electrical signals produced by your heart each time it beats are detected by sensors placed to your skin. A machine records these signals, which a doctor examines to see if they are odd.

An ECG may be requested by a cardiac expert or any doctor who suspects you have a heart condition, including your general practitioner. A professionally qualified healthcare expert can perform the test in a hospital, clinic, or at your GP’s office.

Despite the fact that they have the same name, an ECG is not the same as an echocardiography, which is a heart scan.

Question

Q.1. Mention the Full form of ECG?

1. Electro cardio Group
2. Electrocardiogram
3. Electrocardium Granules
4. Electricity Cardiac Group

Answer: The Correct Answer is Electrocardium. Electrocardiogram is the term for electrocardiogram. The electrocardiogram (ECG) is a graphical representation of the heart’s electrical activity during a cardiac cycle. A gadget called an electrocardiogram is used to measure it.

Q.2. How Many Electrodes are connected to a patient to measure ECG?

1. Two
2. One
3. Four
4. Three

Answer: The Correct Answer is Three. A patient is attached to the equipment with three electrical leads: one to each wrist and one to the left ankle to perform a normal ECG. It keeps track of your heartbeat in real time.

Q.3. Mention the Full Form of CAD?

1. Carotid Artery Disorder
2. Carotid Artery Disease
3. Coronary Artery Disease
4. Coronary Angina Disorder

Answer: The Correct answer is Coronary Artery Disease. Coronary artery disease (CAD) is a condition caused by atherosclerosis and arteriosclerosis. Atherosclerosis is the build-up of cholesterol, fat, and calcium on the walls of coronary arteries, whereas arteriosclerosis is the build-up of calcium that causes artery hardening.

Q.4.Among these which waves represent the excitation of the atria?

1. T-Wave
2. P-Wave
3. QRS Complex
4. ST-Segment

Answer: The Correct Answer is P-Wave. The P-wave represents the electrical excitement of atria depolarisation, which causes both atria to constrict. The repolarization of the ventricles is represented by the T-wave.

Q.5.Which of the following shows the depolarisation of the Ventricles?

1. T-Wave
2. P-Wave
3. QRS Wave
4. PQ Interval

Answer: QRS Wave is the Correct Answer. The depolarization of the ventricles, which initiates ventricular contraction, is represented by the QRS complex. Shortly after Q, the contraction begins, signalling the start of the systole.

Q.6. Generally the End of the T Wave marks the end of the systole?

1. False 
2. True

Answer: It is True. The systole comes to an end at the end of the T-wave. The T-wave denotes the return of the ventricles from an excited to a normal condition, also known as ventricular repolarisation.

Q.7. The Heartbeat of a person can be measured by counting the number of Which wave?

1. QRS Complex
2. T-Wave
3. P-Wave
4. PQ-Wave

Answer: The Correct Answer is QRS Complex. The heartbeat rate of an individual can be determined by counting the number of QRS complexes that occur in a certain interval. Any deviation from the curve’s forms could suggest an anomaly or sickness. As a result, it is extremely important in clinical practice.

Q.8. Determine that among the following which represent the enlargement of auricles?

1. Enlargement of P-Wave
2. Depression of ST Segment
3. Enlargement of QR Statement
4. Elevation of ST segment

Answer: The Correct Answer is Enlargement of P-Wave. The enlargement of the auricles is reflected by the elongation of the P-wave, or the lengthening of the PQ interval, which can also represent the enlargement of the auricles caused by rheumatic fever.

Q.9. What Does the Depression of ST-Segment Depict?

1. Hypokalemia
2. Ischemia
3. Acute Heart Attack
4. Myocardial Attack 

Answer: Ischemia is the Correct Answer. The ST-segment depression indicates Ischemia, which is defined as a lack of blood supply to the heart muscles or a weakening of the heart muscles.

Q.10. Name the muscle which has the longest refractory Period?

1. Smooth Muscles
2. Cardiac Muscles
3. Facial Muscles
4. Skeletal Muscles

Answer: Cardiac Muscle is the Correct Answer. Since cardiac muscles have the longest refractory duration, they never demonstrate summation or tetanus spasm. Cardiac muscles have the shortest latent duration of any muscle.

Q.11. Generally Angina Pectoris is a Symptom of Myocardial Infarction.

1. True
2. False

Answer: This statement is True. Myocardial infarction causes angina pectoris, which is a symptom of the condition. The heart is unable to supply enough blood due to the weakening of cardiac muscles, resulting in acute pain known as angina pectoris. If untreated, tissues will die, resulting in myocardial infarction or an acute heart attack.

Q.12. What is Understood by iso-volumetric systole?

1. The time duration between the closing of AV valves and opening of semilunar valves
2. The time duration between the closing and opening of AV valves
3. The time duration between the closing of semilunar valves and the opening of AV valves
4. The time duration between the closing and opening of semilunar valves 

Answer: The Correct Answer is the time duration between the closing of AV valves and opening of semilunar valves. Iso-volumetric systole is the time between the closure of AV valves and the opening of semilunar valves. Iso-volumetric diastole is the time between the closure of semilunar valves and the opening of AV valves.

Q.13. What is AV Block?

1. Impulse not reaching the AV node
2. Impulse not reaching SA node
3. Impulse not generating in the heart
4. Impulse not reaching purkinje fibers.

Answer: The Correct Answer is Impulse not reaching the AV mode. The term “AV block” refers to when the impulse does not reach the AV node. A Purkinje block occurs when the impulse does not reach the Purkinje fibers.

Q.14. Mention the Main Symptoms of Heart Failure?

1. Vomiting
2. Lung Congestion
3. Pain in the chest
4. Yellowing of Eyes

Answer: The Correct option is Lung Congestion. Heart failure occurs when the heart is unable to pump enough blood to meet the needs of the body’s organs. The most common symptom of heart failure is lung congestion.
