Heart rate and pulse rate usually mean the same number, but they’re not technically the same thing. Heart rate is how many times your heart actually beats per minute. Pulse rate is what you feel in an artery, like your wrist or neck, when blood pushes through it after each heartbeat.
Most of the time, these two numbers match exactly, which is why people use the words interchangeably. But they can split apart in certain heart conditions, and that difference actually matters. Let’s break this down properly.
What Heart Rate Actually Is?
Your heart rate is the number of times your heart’s chambers contract in one minute to push blood out into your body. It’s a direct measurement of your heart muscle doing its job. Doctors usually measure it with an ECG (electrocardiogram), which tracks the electrical signal that makes your heart beat. A stethoscope works too; that’s the “thump-thump” sound you hear when someone listens to your chest.
According to the American Heart Association, a normal resting heart rate for most adults sits somewhere between 60 and 100 beats per minute. Resting just means you’re calm, sitting or lying down, not right after climbing stairs or finishing a coffee. Athletes often sit lower than that, sometimes in the 40s or 50s, simply because a well-trained heart doesn’t need to work as hard per beat.
What Pulse Rate Actually Is?
Pulse rate is what you’re checking when you press two fingers against your wrist. Every time your heart beats, it sends a little surge of blood through your arteries, and that surge creates a small, feelable bump. Count those bumps for a minute (or count for 30 seconds and double it), and that’s your pulse rate.
You can feel a pulse in a few spots: the inside of your wrist (radial artery), the side of your neck (carotid artery), or even the top of your foot. Most people just use the wrist because it’s the easiest.
In a healthy person with a regular heartbeat, every single heartbeat sends out a pulse you can feel. So your pulse rate equals your heart rate, beat for beat. This is exactly why so many people search for “difference between pulse rate and heart rate” and get confused. Under normal conditions, there genuinely isn’t a numerical difference. The difference is in what’s being measured, not the number itself.
Quick Comparison Table to understand heart rate and pulse difference
| Factor | Heart Rate | Pulse Rate |
| What does it measure? | Heartbeats per minute (electrical/mechanical activity of the heart) | Blood surges felt in an artery after each heartbeat |
| How is it measured? | ECG, stethoscope, chest auscultation, smartwatch sensors | Fingers on wrist/neck, pulse oximeter, blood pressure cuff |
| Normal range (adult, resting) | 60–100 bpm | 60–100 bpm |
| Where do you check it? | At the heart (chest) | At an artery (wrist, neck, foot) |
| Can it differ from the other? | Yes, in arrhythmias or weak heartbeats | Yes, it can be lower than the actual heart rate in some conditions |
| Affected by | Fitness, stress, medication, body temperature, illness | Same as heart rate, plus artery health and blood pressure |
| Used to detect | Arrhythmias, heart block, and overall cardiac rhythm | Circulation, blood flow to limbs, basic vital check |
When Heart Rate and Pulse Rate Don’t Match?
In a healthy heart, every electrical signal produces a strong, full contraction, which pushes out a normal amount of blood, creating a pulse you can feel. But in certain arrhythmias, also known as irregular heart rhythms, some of those electrical signals are weak or come too close together. The heart “fires” but doesn’t fill with blood before the next beat, so that particular beat doesn’t push out enough blood to create a noticeable pulse.
This results in your heart beating faster than you can feel at your wrist. This gap is called a pulse deficit, and it shows up in conditions like:
- Atrial fibrillation (AFib) is a very common irregular rhythm where the heart beats fast and erratically. Some beats are too weak to produce a pulse, so your wrist pulse count can read noticeably lower than what an ECG shows.
- Premature ventricular contractions (PVCs) are extra, early heartbeats that don’t always generate enough force for a full pulse.
- Heart block or other arrhythmias are where the timing between the heart’s upper and lower chambers gets thrown off.
- Severe heart failure, a weakened heart muscle, may beat but not pump strongly enough each time, especially during certain irregular beats.
This is exactly why a doctor checking for an irregular heartbeat won’t just feel your wrist. They’ll often listen to your heart directly with a stethoscope while someone else (or they themselves) checks the pulse at the same time, comparing the two counts side by side.
A Simple Real-World Example
Say someone has AFib and their heart is firing 110 times a minute. Because the rhythm is so erratic, only 90 of those beats are strong enough to send a proper pulse to the wrist. If you checked their pulse manually, you’d count 90 bpm and think that’s their heart rate. An ECG, though, would show 110 bpm. That 20-beat gap is the pulse deficit, and it’s a meaningful clinical clue, not just a measurement issue.
This is also part of why fitness trackers sometimes give you a number that feels “off” during intense workouts. Most consumer devices like smartwatches and fitness bands estimate heart rate using light sensors that detect blood flow under your skin. This is really closer to measuring pulse rate, not the heart’s electrical activity. Because of this, it can get confusing for these trackers and almost impossible to understand the pulse and heart rate difference.
Additionally, it is important to understand that for most people doing regular workouts, this barely matters because the two numbers track together. But if you have an arrhythmia, a wrist-based tracker can underestimate how fast your heart is actually beating.
Why Does This Matter for Fitness Tracking?
If you use a fitness watch to monitor your workouts, you’re almost always looking at a pulse-based estimate, not a true heart rate reading from an ECG. For target heart rate zones during exercise, generally 50–70% of your max for moderate activity and 70–85% for vigorous activity, per the American Heart Association, this is perfectly fine for the average person.
But if your tracker has ever shown a number that didn’t match how you felt (way too low when your heart was clearly racing, or jumpy and inconsistent), it could be picking up a weak or irregular pulse signal rather than a true reflection of your heart’s activity. Some newer smartwatches now include actual ECG features for this exact reason, since they’re more reliable for catching irregular rhythms than the basic optical pulse sensor.
When Should You See a Doctor?
Most people never need to think about the difference between pulse rate and heart rate. But a few signs are worth taking seriously:
- Your pulse feels irregular, skips, or flutters
- You notice your heartbeat without trying to feel for it
- Your resting heart rate is consistently above 100 bpm or below 60 bpm without an obvious reason (and you’re not an athlete)
- You feel dizzy, short of breath, or lightheaded, along with an unusual pulse
- A fitness tracker repeatedly flags an irregular rhythm
Any of these are reasonable enough reasons to get checked out. A doctor can run an ECG in minutes, and catching an arrhythmia early generally makes it far easier to manage.
Key Takeaways
- Heart rate is the heart’s actual beats per minute. Pulse rate is what you feel in an artery after each beat.
- In a healthy person, the two numbers are identical.
- The normal resting range for adults is 60-100 bpm.
- The numbers can differ in arrhythmias like AFib, where some heartbeats are too weak to create a felt pulse. This is known as a pulse deficit.
- Fitness trackers mostly measure pulse, not true heart rate, which is usually fine but can be misleading with an irregular rhythm.
- Persistent irregularities, unusually high or low resting rates, or symptoms like dizziness should be taken seriously.
Frequently Asked Questions- FAQs Answered
What is the main difference between heart rate and pulse rate?
Heart rate is the number of times your heart beats per minute, measured directly at the heart. Pulse rate is the number of beats felt in an artery, such as the wrist. In healthy individuals, both values are usually the same.
Is pulse rate always equal to heart rate?
Most of the time, yes. However, they can differ when some heartbeats are too weak to create a detectable pulse, which may occur in conditions like irregular heart rhythms.
What is considered a normal pulse rate for adults?
A normal resting pulse rate for adults ranges from 60 to 100 beats per minute, which is the same range used for resting heart rate.
Why do my heart rate and pulse rate differ on my fitness tracker?
Most wearable trackers measure pulse using optical sensors instead of directly recording heart activity. If your rhythm is irregular or signal quality is poor, the readings may differ from your true heart rate.
Can a low pulse mean a heart problem?
Not always. Athletes often have a naturally low pulse. However, if a low pulse is accompanied by symptoms like dizziness, fatigue, or fainting, it should be evaluated by a doctor.
How do doctors check for a difference between pulse and heart rate?
Doctors compare heartbeats heard through a stethoscope with the pulse felt at the wrist at the same time. A mismatch between the two is called a pulse deficit.
Can stress or anxiety change my pulse rate?
Yes. Stress and anxiety release hormones like adrenaline, which increase heart rate and make your pulse feel faster, especially during tense or anxious situations.
