What is a primary symptom of tachycardia?

• A. Slow heartbeat
• B. Increased heart rate above 100 bpm
• C. Irregular heartbeat patterns
• D. Chest tightness

Answer: (B)

The primary symptom of tachycardia is an increased heart rate above 100 beats per minute (bpm). Tachycardia refers to a condition where the resting heart rate exceeds the normal range, which is typically between 60 to 100 bpm in adults. When an individual experiences tachycardia, their heart is beating faster than usual, which can result from various factors such as stress, anxiety, fever, or underlying medical conditions. Recognizing an increased heart rate is vital in diagnosing and managing this condition, as it can lead to more severe complications if not addressed. Other symptoms like irregular heartbeat patterns or chest tightness may accompany tachycardia but are not definitive characteristics of the condition itself.
