1. What is Heart Rate?

Heart rate is the number of heartbeats per minute (bpm). It's a vital sign that indicates cardiovascular health and fitness level. The normal resting heart rate for adults ranges from 60 to 100 bpm.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• 60 — Number of seconds in a minute
• Pulse Interval — Time between consecutive heartbeats in seconds

Explanation: By measuring the time between two consecutive heartbeats, we can calculate how many beats would occur in a full minute.

3. Importance of Heart Rate Measurement

Details: Monitoring heart rate helps assess cardiovascular health, exercise intensity, and can indicate potential health issues when abnormal.

4. Using the Calculator

Tips: Measure the time between two consecutive heartbeats (pulse interval) in seconds and enter it into the calculator. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal resting heart rate?
A: For adults, 60-100 bpm is normal. Athletes may have lower resting rates (40-60 bpm).

Q2: How do I measure pulse interval accurately?
A: Feel your pulse (wrist or neck) with two fingers, start a stopwatch at one beat, stop at the next beat.

Q3: When is the best time to measure resting heart rate?
A: First thing in the morning, before getting out of bed, for most accurate resting measurement.

Q4: What factors can affect heart rate?
A: Activity level, emotions, medications, caffeine, body position, and air temperature can all affect heart rate.

Q5: When should I be concerned about my heart rate?
A: Consult a doctor if resting rate is consistently above 100 bpm (tachycardia) or below 60 bpm (bradycardia) with symptoms like dizziness.
