What does the term "tachycardia" mean in ECG interpretation?

• A. A heart rate below 60 beats per minute
• B. A heart rate of 100 to 120 beats per minute
• C. A heart rate greater than 100 beats per minute
• D. A heart rate exceeding 140 beats per minute

Answer: (C)

Tachycardia refers to an elevated heart rate, specifically defined as a heart rate greater than 100 beats per minute. This condition indicates that the heart is beating faster than the normal resting rate, which typically ranges from 60 to 100 beats per minute. Understanding this definition is crucial during ECG interpretation, as it may signal underlying medical conditions such as stress, fever, anemia, or cardiovascular issues. Recognizing tachycardia allows healthcare professionals to assess the potential need for further evaluation or intervention based on the individual's symptoms and overall cardiac health.
