What is Heart Rate?
Your heart rate (pulse) is the number of times your heart beats per minute. It's one of the most basic measures of cardiovascular health—and one you can check yourself without any equipment.
Your heart is a muscular pump that beats continuously to circulate blood throughout your body. Each beat delivers oxygen and nutrients to your tissues and removes waste products. Your heart rate adjusts moment-to-moment to meet your body's changing needs.
Why heart rate matters:
- Resting heart rate reflects cardiovascular fitness and overall health
- Elevated resting heart rate is associated with increased cardiovascular risk
- Heart rate response to exercise indicates fitness level
- Heart rate variability reflects nervous system balance
- Abnormal rhythms (arrhythmias) may indicate heart problems
The Fitness Connection
Athletes typically have lower resting heart rates (40-60 bpm) because their hearts are more efficient. A well-conditioned heart pumps more blood with each beat (stroke volume), so it doesn't need to beat as often at rest. This is why resting heart rate decreases with improved cardiovascular fitness.
Understanding Your Results
Heart rate is measured in beats per minute (bpm).

Target Heart Rate Zones During Exercise
Maximum heart rate (approximate): 220 - your age
Exercise intensity zones:
- Moderate intensity: 50-70% of maximum
- Vigorous intensity: 70-85% of maximum
Example for a 40-year-old:
- Maximum heart rate: 220 - 40 = 180 bpm
- Moderate exercise: 90-126 bpm
- Vigorous exercise: 126-153 bpm
What Affects Heart Rate?
Many factors influence heart rate:
Factors That Increase Heart Rate
| Factor | Effect | What to Do |
|---|---|---|
| Exercise and physical activity | Increases | Normal response—heart rate increases to meet increased oxygen demand during exercise. Fit individuals return to resting heart rate more quickly after exercise. |
| Stress, anxiety, or excitement | Increases | Adrenaline and other stress hormones increase heart rate. Chronic stress can keep heart rate elevated. Relaxation techniques help normalize heart rate. |
| Caffeine, nicotine, or stimulants | Increases | These substances stimulate the heart. Caffeine can elevate resting heart rate for several hours. Reducing intake can help lower heart rate. |
| Dehydration or blood loss | Increases | Reduced blood volume causes heart to beat faster to maintain blood pressure. Rehydration or blood replacement normalizes heart rate. |
| Fever or illness | Increases | Heart rate increases about 10 bpm for each degree Fahrenheit of fever. This is a normal response to increased metabolic demands. |
| Certain medications | Increases | Asthma medications (albuterol), some antidepressants, thyroid medications, and others can increase heart rate. Discuss medication effects with your doctor. |
| Anemia or hyperthyroidism | Increases | These conditions increase metabolic demands, causing heart to beat faster. Treating the underlying condition normalizes heart rate. |
Always tell your doctor about medications, supplements, and recent health events before testing.
Sleep and Heart Rate
Heart rate typically decreases during sleep, reaching its lowest point during deep sleep. This is normal. Elevated heart rate during sleep may indicate sleep apnea, heart dysfunction, or other problems and warrants evaluation.
When is Heart Rate Measured?
Heart rate is measured in many situations:
At rest:
- Part of routine vital signs measurement
- Assesses cardiovascular fitness
- Screens for heart rhythm abnormalities
- Monitors medication effects
During exercise:
- Assesses fitness level
- Guides exercise intensity
- Monitors response to cardiac rehabilitation
Continuous monitoring:
- Holter monitor (24-48 hours)
- Event recorder (weeks)
- Implantable loop recorder (years)
- Smartwatches and fitness trackers
When Heart Rate Abnormalities Need Evaluation
Not all heart rate changes are concerning, but some situations warrant medical attention.
Resting heart rate consistently above 100 bpm
Persistent resting tachycardia needs evaluation to identify cause: anemia, hyperthyroidism, heart dysfunction, medications, or other conditions.
Resting heart rate suddenly changes from your baseline
If your normal resting heart rate is 70 bpm and suddenly becomes 95 bpm at rest, something has changed. Evaluation identifies the cause.
Heart rate feels irregular or skips beats
Palpitations, skipped beats, or irregular rhythms may indicate arrhythmia. ECG or Holter monitoring evaluates heart rhythm.
Heart rate doesn't increase with exercise
Chronotropic incompetence (inability to increase heart rate with exercise) may indicate heart dysfunction or medications. Exercise testing evaluates this.
Athlete with resting heart rate below 40 bpm
While low resting heart rate is normal for athletes, extremely low rates (<40) or symptoms (dizziness, fatigue) warrant evaluation to ensure no heart problems.
Heart rate jumps from 60 to 150 bpm and back
Paroxysmal arrhythmias (sudden onset and offset) may indicate supraventricular tachycardia or other arrhythmias. Holter or event monitor captures these episodes.
Abnormal Heart Rhythms (Arrhythmias)
Heart rate alone doesn't tell the whole story—rhythm matters too.
Normal sinus rhythm:
- Regular rhythm originating from the heart's natural pacemaker
- Rate 60-100 bpm at rest
- Increases appropriately with activity
Tachycardia (fast heart rate ＞100 bpm):
- Sinus tachycardia: Normal fast rhythm in response to exercise, stress, fever, etc.
- Supraventricular tachycardia (SVT): Abnormal fast rhythm from upper heart chambers
- Atrial fibrillation: Chaotic, irregular rhythm from upper chambers
- Ventricular tachycardia: Dangerous fast rhythm from lower chambers
Bradycardia (slow heart rate ＜60 bpm):
- Sinus bradycardia: Normal slow rhythm in athletes, during sleep
- Sick sinus syndrome: Diseased sinus node can't maintain adequate rate
- Heart block: Electrical signal blocked between chambers
- Medication effect: Beta blockers, digoxin, others can slow heart rate
Atrial Fibrillation and Stroke Risk
Atrial fibrillation causes fast, irregular heart rhythm and increases stroke risk 5-fold. The chaotic rhythm allows blood clots to form in the heart, which can travel to the brain causing stroke. Anticoagulants (blood thinners) significantly reduce stroke risk in atrial fibrillation.
Your Action Plan Based on Results
If your resting heart rate is 60-100 bpm and regular:
- Continue current lifestyle
- Regular exercise can lower resting heart rate over time
- Monitor periodically to track fitness improvements
- Seek evaluation if rhythm becomes irregular or rate changes suddenly
If your resting heart rate is consistently above 100 bpm:
- Evaluation to identify cause:
- Check for anemia (CBC)
- Check thyroid function (TSH)
- Review medications
- Consider ECG and possibly Holter monitoring
- Evaluate for heart dysfunction if indicated
- Treatment depends on underlying cause
If your resting heart rate is below 60 bpm:
- If you're an athlete and asymptomatic: likely normal, no evaluation needed
- If you're not an athlete OR have symptoms (dizziness, fatigue, fainting): evaluation needed
- ECG to assess rhythm
- Holter monitoring if symptoms intermittent
- Review medications that may slow heart rate
- Evaluate for heart dysfunction if indicated
If your heart rhythm is irregular:
- Evaluation to identify arrhythmia type:
- ECG (if symptoms present during test)
- Holter monitor (24-48 hours)
- Event recorder (weeks)
- Implantable loop recorder (years if symptoms rare)
- Treatment depends on arrhythmia type and symptoms
When Heart Rate Abnormalities Require Urgent Evaluation
- Heart rate above 150 bpm at rest (sustained, not brief)
- Heart rate below 40 bpm with dizziness, fainting, or chest pain
- Irregular heartbeat with stroke symptoms (weakness, speech difficulty)
- Known heart condition with sudden heart rate change
- Chest pain, shortness of breath, or dizziness with abnormal heart rate
- Fainting or loss of consciousness
⚠️ These symptoms require prompt medical evaluation. Call emergency services for chest pain, shortness of breath, fainting, or stroke symptoms. Contact your doctor promptly for other concerning symptoms.
Measuring Your Heart Rate
At your wrist (radial pulse):
- Place index and middle fingers on thumb side of wrist
- Press lightly until you feel the pulse
- Count beats for 30 seconds and multiply by 2 (or count for 60 seconds)
At your neck (carotid pulse):
- Place fingers on either side of windpipe
- Press gently
- Count beats
Using devices:
- Smartwatches and fitness trackers provide continuous monitoring
- Blood pressure monitors often display heart rate
- Pulse oximeters clip on finger and display heart rate
Best practice:
- Measure at the same time daily (morning before getting out of bed is ideal)
- Sit quietly for 5 minutes before measuring
- Avoid caffeine, exercise, or stress before measuring resting heart rate
- Keep a log to track trends over time
Lowering Your Resting Heart Rate
If your resting heart rate is elevated (＞80 bpm), these strategies can help:
Regular aerobic exercise:
- 150 minutes moderate activity or 75 minutes vigorous activity weekly
- Over time, exercise strengthens the heart, lowering resting heart rate
- Significant reduction can be seen in 8-12 weeks of regular exercise
Stress reduction:
- Meditation, deep breathing, yoga, tai chi
- Adequate sleep (7-9 hours nightly)
- Social connection and relaxation
- Chronic stress keeps heart rate elevated
Limit stimulants:
- Reduce caffeine intake
- Avoid nicotine
- Limit energy drinks and other stimulants
Maintain healthy weight:
- Excess weight increases heart rate
- Weight loss reduces resting heart rate
Treat underlying conditions:
- Anemia, hyperthyroidism, and other medical conditions elevate heart rate
- Proper treatment normalizes heart rate
Review medications:
- Some medications increase heart rate
- Discuss alternatives with your doctor if appropriate
