Pulsatile Flow
Pulsatile flow is the rhythmic, on-and-off movement of fluid through a blood vessel or piping system, produced in the body by the heart's cyclic pumping rather than steady laminar flow.
Pulsatile insulin
Pulsatile insulin is a method of delivering insulin in rapid, repeated pulses to mimic the pancreas's natural oscillatory secretion, tested intravenously and intraperitoneally in diabetes.
Pulsating white dwarf
A pulsating white dwarf is a white dwarf star whose brightness varies periodically through gravity-mode oscillations, first seen in 1968 and used in asteroseismology to probe stellar interiors.
Pulsational pair-instability supernova
A pulsational pair-instability supernova is a series of violent pulses and supernova-like mass ejections in very massive stars, distinct from a pair-instability supernova and ending in black hole collapse.
Pulse
Pulse: the arterial pulse and heart rate, a vital sign. Normal adult resting rate 60-100 bpm; measured at radial, carotid, and other sites; history from Herophilus to sphygmograph and modern PPG wearables.
Pulse (2001 film)
Pulse (回路, Kairo) is Kiyoshi Kurosawa's 2001 Japanese horror film in which ghosts spread via the internet and victims vanish leaving black stains; screened at Cannes Un Certain Regard, remade in 2006.
Pulse (2006 film)
Pulse (2006) is Jim Sonzero's American remake of Kiyoshi Kurosawa's Kairo, starring Kristen Bell and Ian Somerhalder as students fighting ghosts spreading via wireless signals. Released by Dimension Films, it grossed $30.2 million worldwide and was panned (11% on Rotten Tomatoes).
Pulse (2025 TV series)
Pulse is a 2025 Netflix medical drama created by Zoe Robyn with Carlton Cuse, set at Miami's Maguire Medical Center during a hurricane. Netflix's first English-language medical procedural; 10 episodes, cancelled July 2025 after one season.
Pulse (nightclub)
Pulse was an LGBTQ+ nightclub on South Orange Avenue in Orlando, Florida, opened in 2004 and the site of the June 2016 mass shooting that killed 49 people.
Pulse (Pink Floyd album)
Pulse (P·U·L·S·E) is Pink Floyd's 1995 double live album from the 1994 Division Bell Tour, produced by David Gilmour and James Guthrie, featuring a complete live Dark Side of the Moon, a blinking-LED heartbeat box, and a UK number 1 chart peak.
Pulse Clean Energy
Pulse Clean Energy, formerly Green Frog Power Ltd, is a British company that owns and operates grid-scale battery storage, rebranded in 2021 after IMCO's full acquisition.
Pulse compression
Pulse compression is a radar signal processing technique that modulates each transmitted pulse in frequency or phase, letting a long pulse achieve the range resolution of a much shorter one.
Pulse contour analysis
Pulse contour analysis is a hemodynamic monitoring method that estimates beat-to-beat cardiac output and stroke volume from the arterial pressure waveform, using an arterial catheter or finger probe.
Pulse detonation engine
A pulse detonation engine is an experimental jet engine that generates thrust from repeated detonation waves, supersonic combustion fronts that burn fuel in abrupt pressure rises.
Pulse Electronics Corporation
Pulse Electronics Corporation, formerly Technitrol, was a San Diego-based manufacturer of passive electronic components including magnetics, antennas, and connectors, taken private in 2015 and sold to Taiwan's Yageo in 2018 for $740 million.
Pulse labeling
Pulse labeling is a cell biology technique that briefly exposes cells to a labeled precursor, such as a radioactive nucleotide, marking molecules synthesized during that interval.
Pulse Medical Imaging (上海博动医疗科技股份有限公司) (Bodong Yixue)
Pulse Medical Imaging (Shanghai Pulse Medical Technology Co., Ltd.) is a Shanghai medical-device company founded in 2015 that develops computational coronary physiology software and intravascular imaging products.
Pulse Music Video Awards
The Pulse Music Video Awards (PMVAs) are Kenyan music video awards presented by Pulse magazine, first held in Nairobi in 2015, with fan votes counting 40% of the score.
Pulse oximetry
Pulse oximetry, invented by Takuo Aoyagi (1972/1974), non-invasively estimates arterial oxygen saturation (SpO2) and pulse rate via light through a fingertip; accuracy is reduced by poor perfusion and darker skin pigmentation, prompting FDA 2025 draft guidance.
Pulse oximetry screening
Pulse oximetry screening is a noninvasive pre-discharge newborn test measuring oxygen saturation to detect critical congenital heart disease, adopted by all US states by 2018.
Pulse Polio
Pulse Polio is India's national immunization campaign, launched in 1995, giving oral polio vaccine drops to every child under 5 on designated days, helping end wild polio by 2011.
Pulse pressure
Pulse pressure (PP) is systolic minus diastolic blood pressure, normally about 40 mmHg. Determined by stroke volume, arterial stiffness, and wave reflection; a wide PP predicts cardiovascular risk, a narrow PP suggests shock or tamponade.
Pulse radiolysis
Pulse radiolysis is a time-resolved spectroscopy technique in which short pulses of high-energy electrons generate reactive intermediates in a sample, followed from femtoseconds to nanoseconds.
Pulse sequence
A pulse sequence in NMR spectroscopy is a programmed recipe of radiofrequency pulses, delays, and magnetic-field gradients that manipulates nuclear spins and determines the recorded signal.
Pulse SILAC
Pulse SILAC, also known as pulsed or dynamic SILAC, is a quantitative proteomics method that measures new protein synthesis and degradation by briefly switching cells to heavy isotope-labeled amino acids.
Pulse Technologies
Pulse Technologies was a Quakertown, Pennsylvania medical device contract manufacturer specializing in complex micro machining, founded in 1993 and acquired by Integer Holdings in 2024.
Pulse therapy
Pulse therapy, or steroid pulse therapy, is a regimen giving very high intravenous steroid doses, usually methylprednisolone, over short periods to rapidly control severe inflammatory or autoimmune disease.
Pulse transformer
A pulse transformer is a transformer designed to transfer rapid electrical pulses between circuits while providing galvanic isolation, used in gate drives, radar magnetrons, and Ethernet data links.
PULSE trial (NCT07621003)
PULSE trial (NCT07621003), PULSed Field Ablation for Atrial Fibrillation Using a Balloon for Early Intervention: German randomized trial of first-line balloon-based pulsed field ablation versus optimized medical therapy in early-stage paroxysmal or persistent AF, 264 participants, Asklepios-sponsored.
Pulse voltammetry
Pulse voltammetry is a family of electroanalytical techniques, including DPV, NPV, and SWV, that applies potential pulses to a working electrode to detect and quantify electroactive species.
