Heart rate is the number of heartbeats per unit of time Time is one of the seven fundamental physical quantities in the International System of Units. Time is used to define other quantities — such as velocity — so defining time in terms of such quantities would result in circularity of definition. An operational definition of time, wherein one says that observing a certain number of repetitions of - typically expressed as beats per minute (bpm In musical terminology, tempo is the speed or pace of a given piece. It is a crucial element of composition, as it can affect the mood and difficulty of a piece) - which can vary as the body's need for oxygen changes, such as during exercise Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health. It is performed for various reasons. These include strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance and for enjoyment. Frequent and regular physical exercise boosts the immune system, and or sleep. The measurement of heart rate is used by medical professionals A health care provider or health professional is an organization or person who delivers proper health care in a systematic way professionally to any individual in need of health care services to assist in the diagnosis Diagnosis is the identification of the nature of anything, either by process of elimination or other analytical methods. Diagnosis is used in many different disciplines, with slightly different implementations on the application of logic and experience to determine the cause and effect relationships. Below are given as examples and tools used by and tracking of medical conditions. It is also used by individuals, such as athletes A sportsperson or athlete is a person who participates regularly in a sport. (For the different meaning of "athlete" in British and American English, see Athlete of the Year.), who are interested in monitoring their heart rate to gain maximum efficiency from their training.
Heart rate is measured by finding the pulse In medicine, a person's pulse is the arterial palpation of a heartbeat. It can be felt in any place that allows for an artery to be compressed against a bone, such as at the neck , at the wrist (radial artery), behind the knee (popliteal artery), on the inside of the elbow (brachial artery), and near the ankle joint (posterior tibial artery). The of the body. This pulse rate can be measured at any point on the body where an artery's Arteries are blood vessels that carry blood away from the heart. All arteries, with the exception of the pulmonary and umbilical arteries, carry oxygenated blood pulsation is transmitted to the surface - often as it is compressed against an underlying structure like bone - by pressuring it with the index and middle finger. The thumb should not be used for measuring another person's heart rate, as its strong pulse may interfere with discriminating the site of pulsation[1] Some commonly palpated sites include:
- The ventral aspect of the wrist In human anatomy, the wrist is variously defined as the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus; and (3) the anatomical region surrounding the carpus including the distal parts of the bones of the on the side of the thumb (radial artery In human anatomy, the radial artery is the main blood vessel, with oxygenated blood, of the lateral aspect of the forearm)
- The ulnar artery The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist
- The neck The neck is the part of the body on many terrestrial or secondarily aquatic vertebrates that distinguishes the head from the torso or trunk. The Latin term signifying "of the neck" is cervical (carotid artery),
- The inside of the elbow The elbow is the region surrounding the elbow-joint—the ginglymus or hinge joint in the middle of the arm. Three bones form the elbow joint: the humerus of the upper arm, and the paired radius and ulna of the forearm, or under the biceps muscle (brachial artery It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm. In some individuals, the bifurcation occurs much earlier and the ulnar and)
- The groin In human anatomy, the groin areas are the two creases at the junction of the torso with the legs, on either side of the pubic area. A pulled groin muscle usually refers to a painful injury sustained by straining the hip adduction muscles (femoral artery Typically the femoral artery can be used as an access artery due to its ease of access as compared to most major arteries. It can be catheterized to gain access to the heart for heart caths, and the implantation of stents. Additionally it can be used to access the vasculature of the brain. This has been used for several stroke procedures)
- Behind the medial malleolus on the feet (posterior tibial artery The posterior tibial artery of the lower limb carries blood to the posterior compartment of the leg and plantar surface of the foot, from the popliteal artery. It is accompanied by a deep vein, the posterior tibial vein, along its course)
- Middle of dorsum of the foot (dorsalis pedis In human anatomy, the dorsalis pedis artery , is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. It terminates at the proximal part of the first intermetatarsal space, where it divides into two).
- Behind the knee (popliteal artery In human anatomy, the popliteal artery is defined as the extension of the "superficial" femoral artery after passing through the adductor canal and adductor hiatus above the knee. The termination of the popliteal artery is its bifurcation into the anterior tibial artery and posterior tibial artery)
- Over the abdomen In vertebrates such as mammals the abdomen constitutes the part of the body between the thorax (chest) and pelvis. The region enclosed by the abdomen is termed the abdominal cavity. In arthropods it is the most distal section of the body which lies behind the thorax or cephalothorax (abdominal aorta The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta)
- The chest (apex of heart), which can be felt with one's hand or fingers. However, it is possible to auscultate Auscultation is the technical term for listening to the internal sounds of the body, usually using a stethoscope; based on the Latin verb auscultare "to listen". Auscultation is performed for the purposes of examining the circulatory system and respiratory system , as well as the gastrointestinal system (bowel sounds) the heart using a stethoscope The stethoscope is an acoustic medical device for auscultation, or listening to the internal sounds of an animal body. It is often used to listen to heart sounds. It is also used to listen to intestines and blood flow in arteries and veins. Less commonly, "mechanic's stethoscopes" are used to listen to internal sounds made by machines,.
- The temple
- The lateral edge of the mandible The mandible or inferior maxillary bone forms the lower jaw and holds the lower teeth in place. It also refers to both the upper and lower sections of the beaks of birds; in this case the "lower mandible" corresponds to the mandible of humans while the "upper mandible" is functionally equivalent to the human maxilla but mainly
A more precise method of determining pulse involves the use of an electrocardiograph Electrocardiography is a transthoracic interpretation of the electrical activity of the heart over time captured and externally recorded by skin electrodes. It is a noninvasive recording produced by an electrocardiographic device. The etymology of the word is derived from electro, because it is related to electrical activity, cardio, Greek for, or ECG (also abbreviated EKG). Continuous electrocardiograph monitoring of the heart is routinely done in many clinical settings, especially in critical care medicine Intensive care medicine or critical care medicine is a branch of medicine concerned with the provision of life support or organ support systems in patients who are critically ill and who usually require intensive monitoring. Commercial heart rate monitors A heart rate monitor is a personal monitoring device that allows a subject to measure their heart rate in real time or record their heart rate for later study. Early models consisted of a monitoring box with a set of electrode leads that attached to the chest. While these still exist, modern versions usually consist of two elements: a chest strap are also available, consisting of a chest strap with electrodes An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit . The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way. The signal is transmitted to a wrist receiver for display. Heart rate monitors allow accurate measurements to be taken continuously and can be used during exercise when manual measurement would be difficult or impossible (such as when the hands are being used).
