Question

What is full name of ECG ? (a) Electron cardiograph (c) Electron colour gram (b) Electro cardiograph (d) Electric colour graph

Short answer

(b) Electro cardiograph

Step-by-step solution

Option (a): Electron cardiograph

This option suggests that ECG stands for "Electron cardiograph." However, this is not the correct full name of ECG, as ECG does not involve the use of electrons for imaging or measuring heart function.

Option (b): Electro cardiograph

This option suggests that ECG stands for "Electro cardiograph." ECG is indeed an abbreviation for electrocardiograph, which is a test that measures the electrical activity of the heartbeat. This is the correct answer.

Option (c): Electron colour gram

This option suggests that ECG stands for "Electron colour gram." This is not the correct full name of ECG, as it does not relate to heart function, nor does it exist as a known term in medical or scientific fields.

Option (d): Electric colour graph

This option suggests that ECG stands for "Electric colour graph." While this option includes the word "electric," it is not the correct full name of ECG, as it does not accurately describe the purpose of the test. In conclusion, the correct answer is: (b) Electro cardiograph

Key concepts

Medical Terminology

Understanding medical terminology is crucial for interpreting the language used in healthcare. One popular term often encountered in medical studies is "ECG," which stands for "Electrocardiograph." This is a compound word combining "electro," referring to electrical activities, and "cardiograph," meaning a record or display of heart-related activities. Mastery of such terms helps students and professionals communicate effectively.
Medical terminology often uses prefixes and suffixes adapted from Greek and Latin, allowing for precise descriptions. This system also helps categorize information through recognizable patterns.

• "Electro-" denotes electrical functions.
• "Cardio-" refers to the heart.
• "-graph" signifies a recording or a written output.

Recognizing these components enables easier understanding of complex medical concepts.

Heartbeat Electrical Activity

The heart's function can be visualized through its electrical activity, which is crucial for its operation. The Electrocardiograph, commonly known as ECG or EKG, is a tool that allows healthcare providers to assess this activity. When the heart beats, it generates electrical impulses that create patterns.
The heart has its own electrical system, which governs the rhythm and strength of these beats. An ECG captures these impulses using sensors attached to the skin. The results are displayed as wave patterns, with each part of the pattern providing insights about different heart functions.

• "P wave" denotes atrial contraction.
• "QRS complex" shows ventricular contraction.
• "T wave" indicates ventricular relaxation.

Reading these patterns helps in diagnosing various heart conditions, such as arrhythmias or heart attacks.

Multiple Choice Questions

Multiple choice questions (MCQs) are a standardized method of assessing knowledge. They present a question followed by several possible answers, but typically only one correct answer. Their design helps evaluate a student's understanding efficiently and effectively.
When interpreting MCQs, it's important to thoroughly read the question to identify key points. Especially in scientific fields, similar-sounding terms may be included, requiring a careful evaluation of each option.

• Option analysis is critical to exclude incorrect answers based on known facts.
• Process of elimination can aid in identifying the correct choice.
• Consistent practice can improve accuracy and confidence in answering these questions.

MCQs are a valuable tool in pinpointing areas of strength and topics that may need additional study.

Scientific Nomenclature

Scientific nomenclature is a structured method of naming things, ensuring each term is universally understood in the scientific community. It follows specific rules to avoid variations and ambiguity.
In the context of medical instruments like the Electrocardiograph (ECG), nomenclature helps classify and differentiate it from other similar-sounding terms.
Electrocardiography gets its name from Latin and Greek roots, offering a detailed depiction of its purpose. The discipline's reliance on this structured language facilitates global scientific communication.

• Nomenclature eliminates confusion by providing consistent naming conventions.
• It enhances clarity, especially among varied languages and disciplines.
• Proper understanding supports better learning and communication in science.

Familiarity with scientific nomenclature is essential for anyone venturing into fields related to science and medicine.
