Heart rate monitor

carrying out the Harvard step test practical. This test is where a person carries out a period of exercise for a certain length of time and then records their heart rate before and for so long after the period. This shows how fit and healthy the heart is by showing how long it takes for the heart to go back to a regular resting pulse rate. “The cardiovascular response to acute exercise is centred on the principle that the cardiovascular system fulfils three primary functions: to deliver…

Mr. Borg’s dopamine drip was titrated to 9 mcg/kg/min in 500 ml D5W to maintain a systolic pressure of 90 mm Hg. Dopamine is an organic chemical that occurs naturally in the body to keep the heart pumping. Dopamine (Intropin) can be used to treat low heart rate during shock (“Dopamine Injection: Uses, Dosage & Side Effects - Drugs.com,” 2015). Furosemide (Lasix). The physician prescribed furosemide (Lasix) 80 mg, administer IV injection over 1 to 2 min to decrease fluid…

known as cardiac arrhythmia is a group of of conditions where the heartbeat is irregular and or too fast or too slow. Tachycardia is known as a heart rate that is over 100 beats per minute for adults ,while Bradycardia is too slow with below 60 beats per minute. Majority of arrhythmia issues are not serious, but some predispose one to complications like heart failure or a stroke. Arrhythmia are the leading cause of sudden cardiac death, with 400,000 victims a year. There are four main types of…

Table 3 depicts the interval, or the amount of time, between two pulses. Table 4 depicts the calculate heart rates of volunteer 1 and 2 based upon the amplitude and interval of each pulse. As interval decreases, heart rate increase and amplitude does not affect rate, but represents the…

affected Heart Rate This lab experiment was conducted on Daphnias to test the chemical effects on its heart rate. In this experiment we determined the effects of caffeine and alcohol on the small organism. If the Daphnia is submerged in alcohol the heart rate will slow down, as if it’s submerged in caffeine it will speed up. The experiment measured how the stimulant caffeine or alcohol affected the Daphnia. The objective was to see how alcohol and caffeine would affect the Daphnia's…

Heart rate variability is the normal beat-to-beat alterations of heart rate and reflects the ANS’s ability to respond to the environment (McMillan, 2002). Heart rate variability measurements were obtained from 24-hour Holter electrocardiogram recordings and derive from the analysis of consecutive R-R intervals (Gang & Malik, 2003). The predominant method for analysis of HRV is time and frequency domain analysis, and these measurements also provide information about ANS activity (Gang &…

Introduction The purpose of the lab was to see the effects of heart rate and blood pressure when 3 male and 3 female students exercised compared to when they were at rest. My hypothesis is that the data from the exercise part of the experiment will cause both the heart rate and blood pressure (systolic and diastolic) to increase more than the resting state. Methods Resting heart rate was recorded in the begging of class. Then the class was divided into groups and from each group, there was a…

The effect of music genre on heart rate and blood pressure By: Kristin Hall Introduction: Heart rate measures the speed of the number of times the heart pulses per a unit of time, normally beats per minute (Biology Online, 2011). The number of pulses is based off the number of contractions of the ventricles. This number shows how much blood is flowing through the body, and thus how much hemoglobin and oxygen is being transported. When muscles become active they require more oxygen to function…

including misrepresentation of interbank borrowings as well as reporting incredulously low rates to allow the perception of financial health. Many banks were involved and colluding in these practices, therefore one can certainly conclude that the problem does not lie solely with the panel banks but the financial system and its governing regulators as well. LIBOR stands for London Interbank Offered Rate; it was intended to be a firm representation of the cost of funding for the largest…

on the walls of blood vessels, it is controlled by a negative feedback system where heart rate and blood volume need to be altered in order to control the pressure. Local negative feedback systems and heart rate is regulated but the cardiovascular centre which also in turn controls neural and hormonal mechanisms. Neurons regulate heart rate and contractility and some neurons inhibit, stimulate or control heart rate by causing constriction which also controls the blood pressure. The…
