  • Continuing the comparison between a psychophysiologist and a physiological psychologist, a psychophysiologist may look at how exposure to a stressful situation will produce a result in the cardiovascular system such as a change in heart rate (HR), vasodilation/vasoconstriction, myocardial contractility, or stroke volume. (wikipedia.org)
  • Pulse
  • Even if you're not a gym rat or elite athlete, knowing your heart rate (or pulse) can help you track your health and fitness level. (heart.org)
  • If it is significantly darker, due the pulse causing a temporary increase in the amount of blood that is travelling through the measured area, that is counted as a heart pulse. (wikipedia.org)
  • This results in a pulse (blood pressure) weaker than expected and triggers normal homeostatic mechanisms that try to compensate by constricting arteries and increasing heart rate (the turbulence onset part of HRT). (wikipedia.org)
  • During the minute that you have stopped exercising to take your pulse, your heart will have slowed down, and you won't get an accurate reading. (smartdraw.com)
  • Users can see their heart rate measurements sorted by time of day, by category (after waking up, before exercise, etc.), and also see visualizations of their pulse waveforms Azumio released a smart alarm clock and sleep analysis tool, Sleep Time, on March 11, 2012. (wikipedia.org)
  • respiration
  • Respiration gives rise to waves in heart rate mediated primarily via the PSNS, and it is thought that the lag in the baroreceptor feedback loop may give rise to 10 second waves in heart rate (associated with Mayer waves of blood pressure), but this remains controversial. (wikipedia.org)
  • This heart rate variation is associated with respiration and faithfully tracks the respiratory rate across a range of frequencies. (wikipedia.org)
  • If you don't want to wait that long, however, health-tech company Azoi has launched the Kito+, a credit-card sized unit that pairs with an iPhone app to measure heart-rate, ECG, blood oxygen, respiration rate and skin temperature. (9to5mac.com)
  • slows
  • There are many ways in which the heart rate speeds up or slows down. (wikipedia.org)
  • A plot of this averaged RR interval list (called a PVC tachogram) not only confirmed their observation that heart rate sped up for a few beats after a PVC, but highlighted another less obvious feature, that heart rate then slows down beyond what it was before the PVC, before returning to the original heart rate. (wikipedia.org)
  • cardiac
  • That is, a PVC interrupts the normal cardiac cycle, so the ventricles of the heart haven't had time to fill up to their normal level, before contracting and pumping their contents out. (wikipedia.org)
  • Physiological responses also can be measured via instruments that read bodily events such as heart rate change, electrodermal activity (EDA), muscle tension, and cardiac output. (wikipedia.org)
  • tachycardia
  • Tachycardia is a fast heart rate, defined as above 100 bpm at rest. (wikipedia.org)
  • Central nervous system depressants or sedatives decrease the heart rate (apart from some particularly strange ones with equally strange effects, such as ketamine which can cause - amongst many other things - stimulant-like effects such as tachycardia ). (wikipedia.org)
  • Garmin
  • We are proud to support our men and women in uniform in both their training and even with high-end wrist top GPS navigation units like the Garmin fenix, which is very popular with military personnel', says Rusty Squire, President of the Heart Rate Watch Company. (prweb.com)
  • interval
  • The AquaPulse announces your heart rate in real time, and at a user definable interval. (chipchick.com)
  • There is an ideal heart rate range that you want to hit while you're exercising, this range is determined by age, and shifts depending on the reason you're exercising (fat burning versus high intensity interval training). (chipchick.com)
  • A clinical sign of domperidone's potential toxicity to the heart is the prolongation (lengthening) of the QT interval (a segment of the heart's electrical pattern). (wikipedia.org)
  • Holter
  • These thresholds were applied to Holter records from a total of 1191 patients who had experienced a heart attack. (wikipedia.org)
  • blood
  • Due to individuals having a constant blood volume, one of the physiological ways to deliver more oxygen to an organ is to increase heart rate to permit blood to pass by the organ more often. (wikipedia.org)
  • High blood pressure medications are used to block these receptors and so reduce the heart rate. (wikipedia.org)
  • This heart rate variation is associated with Mayer waves (Traube-Hering-Mayer waves) of blood pressure and is usually at a frequency of 0.1 Hz or a 10-second period. (wikipedia.org)
  • reliability
  • The company claims that Apple violated three of its patents for improving the accuracy and reliability of heart-rate data when using the photoplethysmography (PPG) approach used in the Apple Watch. (9to5mac.com)
  • Watch
  • Apple Watch running the original 1.0 software rather reliably recorded a user's heart rate every ten minutes. (9to5mac.com)
  • With Watch OS 1.0.1, users noticed that heart rate records were no longer being kept as frequently . (9to5mac.com)

  • By holding the arrow buttons you can adjust the time increment between heart rate announcements. (chipchick.com)
  • Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate. (wikipedia.org)
  • With the aim of integrating various aspects of health into a single user timeline, Argus was designed to integrate data from Instant Heart Rate, Sleep Time, Fitness Buddy, and Instant Fitness into a single location. (wikipedia.org)
  • oxygen

  • track
  • What should your heart rate be when working out, and how can you keep track of it? (heart.org)
  • The AquaPulse by Finis uses infrared technology to track your heart rate via your ear lobe, it is then verbally announced while you swim. (chipchick.com)
