{{Anchor|Pulse deficit}}{{Further|Heart rate}}
The rate of the pulse can be observed and measured on the outside of an artery by tactile or visual means. It is recorded as arterial beats per minute or BPM. Although the pulse and heart beat are related, they are not the same. For example, there is a delay between the onset of the heart beat and the onset of the pulse, known as the [[pulse transit time]], which varies by site. Similarly measurements of [[heart rate variability]] and pulse rate variability differ.<ref name="Yuda2020">{{cite journal |last1=Yuda |first1=Emi |last2=Yamamoto |first2=Kento |last3=Yoshida |first3=Yutaka |last4=Hayano |first4=Junichiro |title=Differences in pulse rate variability with measurement site |journal=Journal of Physiological Anthropology |date=21 February 2020 |volume=39 |issue=1 |pages=4 |doi=10.1186/s40101-020-0214-1 |pmid=32085811 |issn=1880-6791 |pmc=7035641|doi-access=free}}</ref> 

In healthy people, the pulse rate is close to the [[heart rate]], as measured by [[ECG]].<ref name="Yuda2020"/> Measuring the pulse rate is therefore a convenient way to estimate the heart rate.<ref>{{cite web|title=Pulse Rate Measurement|url=http://www.webmd.com/heart-disease/pulse-measurement|work=Healthwise|publisher=WebMD|access-date=14 March 2011|archive-date=23 July 2012|archive-url=https://web.archive.org/web/20120723104209/http://www.webmd.com/heart-disease/pulse-measurement|url-status=live}}</ref> '''Pulse deficit''' is a condition in which a person has a difference between their pulse rate and heart rate. It can be observed by simultaneous [[palpation]] at the [[radial artery]] and  [[auscultation]] using a [[stethoscope]] [[apex beat|at the PMI, near the heart apex]], for example. Typically, in people with pulse deficit, heart beats do not result in pulsations at the periphery, meaning the pulse rate is lower than the heart rate. Pulse deficit has been found to be significant in the context of [[premature ventricular contraction]]{{cn|date=June 2024}} and [[atrial fibrillation]].<ref>{{cite journal |last1=Karadavut |first1=Serhat |last2=Altintop |first2=Ismail |title=Pulse deficit in atrial fibrillation — a different perspective on rhythm or rate control strategy |journal=Kardiologia Polska |date=30 November 2021 |volume=79 |issue=11 |pages=1231–1238 |doi=10.33963/KP.a2021.0107|doi-access=free |pmid=34506629 }}</ref>
