What is normal heartbeat?

A normal human heartbeat usually ranges from 60 to 100 beats per minute (bpm) when resting. This range can vary slightly from person to person and may be affected by factors such as age, physical activity, and emotional state.

Here's a breakdown of typical heart rate ranges:

1. Resting Heart Rate: The resting heart rate is the number of beats per minute (bpm) when you are at complete rest. It's usually measured first thing in the morning after waking up. Typically, a normal resting heart rate falls within the range of 60 to 100 bpm.

2. Target Heart Rate: When engaging in physical activity, your target heart rate is the range at which you can achieve optimal cardiovascular benefits. It is usually calculated based on your age, resting heart rate, and fitness level. In general, a moderate-intensity target heart rate falls within 50% to 70% of your maximum heart rate.

3. Maximum Heart Rate: The maximum heart rate is the highest number of beats per minute (bpm) that your heart can reach during intense physical exertion. It is affected by factors such as age and overall fitness. A rough estimate for calculating maximum heart rate is to subtract your age from 220. However, it's essential to consult with a healthcare professional for a precise measurement.

4. Bradycardia: A heart rate below 60 bpm is known as bradycardia. While it can be normal for athletes and highly trained individuals, a slow heart rate not caused by these factors may require medical evaluation.

5. Tachycardia: A heart rate above 100 bpm is known as tachycardia. Short periods of faster heart rate during or right after physical activity or as a response to stress are considered normal. However, persistent tachycardia without an identifiable cause should be evaluated by a medical professional.

6. Arrhythmia: Arrhythmia refers to any deviation from a regular heart rhythm. It can involve the heart beating too fast, too slow, or irregularly. Arrhythmias may or may not be a cause for concern and require medical attention.

It's important to note that individual variations exist, and what's considered normal for one person may not be for another. If you have any concerns about your heart rate or experience abnormal symptoms such as dizziness, chest pain, or shortness of breath, consult with a healthcare professional.
