parameters of the cardiac pacemaker pulses: duration‚ frequency‚ voltage and period. Also to calculate battery lifetime of the pacemaker. Theory Many organs are being stimulated by electric pulses nowadays to restore lost or inadequate functions. Electric stimulation is often more effective than pharmacotherapy. When heart pulse rate becomes less than 40 per minute‚ than the natural pacemaker of the heart can be substituted by artificial periodic electrical pulses of a special generator. This generator

Variables Affecting Human Arterial Pressure and Pulse Rate BIOL-204 Introduction: The woozy feeling when standing up too quickly. After going for a run‚ feeling as if one more beat and the heart would project itself out of the chest. Or quite the opposite and being in a very relaxed state. These are all changes one experiences at some time or another. What causes the different feelings and how each variable affects pulse rate and blood pressure has many wondering. Because of this curiosity

breathing rate? Justification Pulse is an ongoing wave of pressure in the arteries‚ caused by pumping of heart. Pulse can be measured on the wrist‚ neck‚ back of the knee or any other pulse point where arteries run close to the surface of the skin and compress on the bone. Pulse rates vary from person to person. Your pulse is lower when you rest and increases when you exercise. More oxygen rich blood is needed by the body when exercising so knowing how to take your pulse can help you evaluate your

The study of biological psychology can be dated back to Avicenna a physician who in The Canon of Medicine‚ recognized physiological psychology in the treatment of illnesses involving emotions‚ and developed a system for associating changes in the pulse rate with inner feelings‚ which is seen as an anticipation of the word association test. Avicenna also gave psychological explanations for certain somatic illnesses‚ and he always linked the physical and psychological illnesses together. He explained

One method scientists are using currently to map the function of the human brain is a MRI scan of the brain. It uses a magnetic field and pulses of radio wave energy to make pictures of radio wave energy to make pictures of organs and structures inside the body. An MRI gives different information about structures than other scanners‚ such as an X-ray and ultrasound. MRIs can show problems

frequency is meaningless. UWB systems use electromagnetic pulses‚ just pulses‚ not short wave-packets. Pulse repetition frequency (PRF) couldnot be declared‚ as is not a correct figure of electromagnetic spectrum occupation. PRF is typically in the range of 1 to 50 MHz.The pulse repetition period ismodulated to carry information or coding. A precise frequency description of UWB emission could be given by the Fourier transform of the pulse. Being the pulse very narrow‚ in the order of hundreds of picoseconds

Variables Affecting Human Arterial Pressure and Pulse Pressure BIOL 204-506 Remi Ben-Davies Dashaun Lee‚ Amanda Easter‚ and Lynne Baker April 9th‚ 2015 1 Introduction: Purpose: The purpose of this experiment was to determine how different variables may affect arterial pressure and pulse rate. Two subjects were used as models for the tests. The first two tests required the use of sphygmomanometers and stethoscopes to measure the arterial pressure and pulse rate. The last test required sphygmomanometers
