1. What is Heart Rate?

Heart rate (HR) is the number of heartbeats per minute (bpm). It's a vital sign that provides important information about cardiovascular health and fitness.

2. How Does the Calculator Work?

The calculator uses the heart rate equation:

Where:

• \( HR \) — Heart rate in beats per minute (bpm)
• \( Beats \) — Number of heartbeats counted
• \( Time_{min} \) — Time period in minutes during which beats were counted

Explanation: The equation converts your counted beats over any time period into the standard beats-per-minute measurement.

3. Importance of Heart Rate Measurement

Details: Monitoring heart rate helps assess cardiovascular fitness, detect potential health issues, and guide exercise intensity. It's used in medical settings, athletic training, and general health monitoring.

4. Using the Calculator

Tips: Count your pulse for at least 15-30 seconds (enter as 0.25 or 0.5 minutes) for more accurate results. For irregular heartbeats, count for a full minute.

5. Frequently Asked Questions (FAQ)

Q1: What's a normal resting heart rate?
A: For adults, 60-100 bpm is typical. Athletes may have 40-60 bpm. Consult a doctor if consistently outside these ranges.

Q2: Where's the best place to measure pulse?
A: Common sites are wrist (radial artery) or neck (carotid artery). Use fingertips, not thumb.

Q3: When should I measure my heart rate?
A: For resting rate, measure first thing in morning before getting up. For exercise intensity, measure during/after activity.

Q4: Does this work for irregular heartbeats?
A: For irregular rhythms (arrhythmias), count for a full minute for most accurate results.

Q5: How does heart rate relate to exercise?
A: Target heart rate zones help optimize workouts. Maximum HR is roughly 220 minus your age.
