Heart rate vs pulse: is there a difference?

Heart rate and pulse usually describe the same number, but they are not exactly the same measurement. Heart rate is how many times your heart beats in a minute. Pulse rate is how many pressure waves you can feel in an artery in a minute. So, are heart rate and pulse the same? Usually, yes, when the rhythm is steady. With an irregular or very fast rhythm, some heartbeats may not produce a strong pulse you can feel, so the readings can differ. An observational study comparing radial pulse counts with ECG heart rates found meaningful disagreement in acutely ill hospital patients.

Heart rate and pulse: what is the difference?

Each heartbeat begins with electrical activity that coordinates the heart muscle’s contraction. That contraction sends blood into the arteries, creating a pressure wave. An ECG records the heart’s electrical activity; a pulse check detects the wave at an artery, often at the wrist. They are connected parts of one cycle, but one is a count of cardiac beats and the other is a count of felt arterial waves.

For most people at rest, a calm pulse count is a practical estimate of heart rate. But a finger check, a watch, a blood pressure cuff, and an ECG do not all measure the same thing in the same way. In an observational study of acutely ill patients, radial pulse rates recorded by nurses and ECG heart rates had only moderate correlation, and the difference varied between people. The hospital setting limits how directly that result applies to a healthy person checking at home, but it shows why a pulse count is not a diagnostic ECG. Opio and colleagues, 2017

Term	What it counts or measures	Common way to check
Heart rate	Heartbeats per minute	ECG, wearable sensor, or clinical monitor
Pulse rate	Felt arterial waves per minute	Fingers at the wrist or neck, or a pulse sensor
Pulse pressure	The difference between systolic and diastolic blood pressure	Subtract the bottom blood pressure number from the top number

Is pulse pressure the same as pulse rate?

No. Despite the shared word, pulse pressure is a blood pressure calculation, not a beat count. For example, if a blood pressure reading is 120/80 mmHg, pulse pressure is 40 mmHg. It does not tell you how many times your heart beats in a minute. Read more in pulse pressure: what it is and the normal range and systolic vs diastolic: the top and bottom numbers.

Why might heart rate and pulse not match?

A pulse wave can be weak or absent at the wrist for a heartbeat that still appears on an ECG. Clinicians call the difference between the heart’s rate and the palpable pulse a pulse deficit. Atrial fibrillation, a fast rhythm, or other changes in how strongly the heart fills and pumps can make the pulse irregular or harder to count. Do not try to identify a rhythm problem by feel alone.

A study in 273 people with persistent atrial fibrillation found that a larger pulse deficit was associated with lower exercise capacity. That was a study of people already diagnosed with atrial fibrillation, not evidence that a pulse gap at home means you have it. Karadavut and Altintop, 2021

Pulse palpation can flag an irregular rhythm, but it cannot confirm atrial fibrillation. In a study of adults aged 75 and 76, pulse palpation was less accurate for screening than a single lead ECG. A separate primary care study in people 65 and older also found better diagnostic accuracy with a handheld ECG than with pulse palpation. In both settings, a clinician needs to interpret an ECG or other appropriate test to confirm what an irregular pulse means. Gudmundsdottir et al., 2021 Verbiest-van Gurp et al., 2022

Other everyday factors can temporarily change heart rate, including recent activity, stress, fever, stimulants such as caffeine, and some medicines. Since these can affect the heart’s rate or the quality of a wrist reading, compare readings under similar conditions and ask your clinician about a persistent change. Heart rate after eating and heart rate while sleeping cover two situations that can prompt questions.

How to check your pulse at rest

If you want a simple resting pulse count, sit quietly for several minutes first. Place your index and middle fingers on the thumb side of the opposite wrist, then count the beats for a full 60 seconds. A full minute can be especially helpful if the rhythm feels uneven. Avoid pressing hard, and do not use your thumb because it has its own pulse. Write down the time, the number, whether the rhythm felt regular, and anything relevant such as recent exercise or caffeine.

These steps give you a repeatable observation, not a diagnosis. A wrist wearable can help you notice a pattern, but a device reading is not a substitute for a clinical assessment if you feel unwell or the rhythm seems irregular. A research study comparing pulse checks with ECG found that measurement accuracy in practice varied, particularly when heart rate was high. Opio et al., 2017

To make comparisons more useful, check at roughly the same time of day and after resting. If you have a heart condition, implanted device, or symptoms during activity, follow your clinician’s instructions for monitoring. See normal resting heart rate by age for more context, and how to take your blood pressure at home if you are also tracking blood pressure.

When should you get medical help?

An unusually low resting heart rate together with dizziness or fainting deserves medical attention. Athletes can have a low resting rate, but symptoms matter and a new change should be discussed with a clinician. A fast, irregular heartbeat also warrants prompt medical advice, especially if it is new, keeps returning, or comes with weakness or breathlessness.

Call 911 for chest pain, severe shortness of breath, fainting, or other severe symptoms. If you have a fast or irregular pulse and feel faint, very weak, or suddenly unwell, seek urgent help. Do not drive yourself if symptoms are severe. These warning signs are more important than a single number on a watch or a pulse check.

For a new or persistent difference between an ECG or monitor reading and your wrist pulse, tell a healthcare professional what each device showed and when. A clinician can check the rhythm and decide whether further evaluation is needed. A one-time difference can also come from timing, movement, or an imperfect measurement, so avoid drawing a conclusion from one reading alone.

What about supplements?

Supplements are not a way to diagnose an irregular rhythm or make a heart rate and pulse match. Evidence for products marketed for heart and circulation varies, and products should not replace evaluation or prescribed care. Our scores are strict: we compare labels with human evidence, dose transparency, and value, and a score is not a promise of results. Read our heart and circulation supplements comparison and our Cardio Shield review for the label details. Talk to your doctor before using a supplement, especially if you take medications, because interactions and individual risks matter.

Next step

If you are mainly trying to understand the number shown by a watch or fitness tracker, read normal resting heart rate by age next. If you have a new irregular pulse or symptoms, contact a clinician instead of relying on an article or device reading.

Frequently asked questions

Is heart rate and pulse rate the same thing?

They usually give the same number when the rhythm is steady. Heart rate is the number of heartbeats per minute; pulse rate is the number of pressure waves you can feel in an artery. Some heartbeats may not create a strong palpable wave, which can make the counts differ. Opio et al., 2017

Is heart rate the same as pulse on a smartwatch?

A smartwatch estimates pulse from changes in blood flow at the skin. Many devices use that signal to estimate heart rate, but they are not recording the heart’s electrical activity like an ECG. If a reading conflicts with how you feel or your clinician’s measurement, ask about it rather than treating the watch as a diagnosis.

What does it mean if my pulse is lower than my heart rate?

It can mean some heartbeats are not producing a strong pulse wave that you can detect at the wrist. A pulse deficit is one explanation, and irregular rhythms can be involved. A repeated difference should be assessed by a healthcare professional; a pulse check alone cannot identify the cause. Karadavut and Altintop, 2021

Can an irregular pulse mean atrial fibrillation?

It can be a reason to seek assessment, but an irregular pulse does not confirm atrial fibrillation. Studies comparing pulse palpation with ECG screening found that palpation missed some cases and also produced positive results that needed confirmation. An ECG is used to evaluate the rhythm. Gudmundsdottir et al., 2021 Verbiest-van Gurp et al., 2022

Is pulse pressure and pulse rate the same?

No. Pulse pressure is the difference between the systolic and diastolic blood pressure numbers. Pulse rate is a count per minute. For more, see pulse pressure: what it is and the normal range.

Results vary from person to person. Talk to your doctor, especially if you take medications. New or worsening symptoms deserve medical care. An unusually low resting rate with dizziness or fainting, or a fast irregular rate, needs prompt medical attention.
