What does tachycardia refer to?

1. Low blood pressure

2. Irregular breathing

3. Fast heartbeat, over 60 beats per minute

4. Fast heartbeat, per 100 beats per minute

The correct answer is: Fast heartbeat, per 100 beats per minute

Tachycardia specifically refers to a condition characterized by an elevated heart rate. Typically, a normal resting heart rate is between 60 and 100 beats per minute. When the heart beats at a rate exceeding 100 beats per minute, it is classified as tachycardia. This increased heart rate can occur in various situations, such as physical exertion, stress, or underlying health conditions. The choice that indicates fast heartbeat, per 100 beats per minute, accurately identifies tachycardia as it captures the essence of the condition, defining it as a heart rate above 100 beats rather than simply stating it as "fast." This distinction is crucial for understanding the clinical implications of tachycardia, as it may signal the need for medical evaluation or intervention.
