What does tachycardia refer to?

• A. Low blood pressure
• B. High blood pressure
• C. Slow heart rate
• D. Fast heart rate

Answer: (D)

Tachycardia refers to a fast heart rate, typically defined as a resting heart rate that exceeds 100 beats per minute in adults. It can occur in response to various factors such as stress, anxiety, fever, or exercise. Understanding heart rate is crucial in assessing a person's cardiovascular health. A normal heart rate typically ranges from 60 to 100 beats per minute, so when the heart beats faster than this threshold, it is classified as tachycardia. This condition can be a sign of underlying health issues and requires careful monitoring and evaluation by healthcare professionals.
