In healthy dogs, heart rate fluctuates during the day. Heart rate variability (HRV) reflects the autonomic nervous system´s regulation of the cardiovascular unit. Heart rate variability shows the balance between the sympathetic and parasympathetic nervous system, also called sympathovagal balance. Heart rate variability can be measured by time domain - and frequency domain analysis. In a time domain analysis you study the beat-to-beat-interval (RR-interval) in an electrocardiogram (ECG), while a frequency domain analysis can be used to determine the size of the variability.

SAMMANFATTNING Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).

What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..

It?s been noted that cows held at the section of ruminant medicine and epidemiology, Swedish University of Agricultural Sciences (IME), used for the education of veterinary students, have a lower heart rate than what is considered normal for ruminants. In this investigation the heart rates of seven lactating cows were recorded continuously during the period around drying off. The first recording took place at the farm from where the cows were bought, and then their heart rate was monitored after their arrival at IME and further on until they were completely dried off. The results were then compared to the heart rate of seven already dried off cows from the same farm.

Heart failure is the most common reason to hospitalization among persons over 65 years old. Self-care is an important part in the treatment of heart failure, but poor information and knowledge limits the ability of self-care and increases the risk of admission to hospital.The aim of the study was to investigate what information patients with heart failure describes that they receive from health care personal, how information is perceived, who provides the information, and on what occasions it is given. The aim was also to investigate whether patients' perception of knowledge about heart failure increased after hospitalization.The study is cross-sectional study with a descriptive design. A consecutive selection was used. A questionnaire was filled in by 28 participants.The study has shown that patients with heart failure largely experience information about heart failure inadequate.

Background:For patients with severe heart disease, may heart transplantation be the only opportunity for survival. Previous research highlights the importance of the nurse's role as supporters and knowledge brokers. People who has undergone heart transplant may be changed forever. Having to undergo a heart transplant can lead to that patients end up in a traumatic crisis.

AbstractThis report aims, through interviews, observations and literature review to examine what some of the youngest children know about the heart, blood and bloodstream. The sample size was twenty children, half of them are at the age of three and the other half is at the age of six.The interviews showed that children at the age of six had better knowledge than children at the age of three, but one child knew that we have the blood corpuscle in the body. He was also the only one who mentioned the blood corpuscle of all children who participated in the research. Children at the age of three could not see the functional relationship between the blood and heart. One child who was six years told that the air we breathe goes directly in the heart from where the blood is circulating to the rest of the body, together with the food.Keywords: heart, blood, bloodstream, the body.

The aim of the study was to describe how women and men with diagnosed heart disease experience their health-related quality of life and what differences there is between genders in their quality of life and also describe problems after receiving the diagnosis. The study also aimed to describe rehabilitation of patients with heart disease. The study was a descriptive literature study based on scientific articles. It emerged that both women and men with heart disease experienced lower quality of life compared to normative data. There was a significant difference between women and men both one year and three years after receiving the diagnosis heart disease, which showed that women experienced lower quality of life than men.

This student report is a literature study about cardiac insufficiency in cats and it is written mainly for veterinary nurses.

The purpose of the thesis is to demonstrate how high frequency trading affects the stock market. The growing high frequency trading is affecting the game plan on the financial markets and concerns have grown about the high frequency users intentions with their business. It is difficult to receive an overall picture of the subject because the lack of previous research and even the research that exist do not show the entire picture. The thesis contributes to the research through a comprehensive picture of the present debate as well as the previous research through a literature study. Our results showed that high frequency trading provides liquidity to the market, there is a statistical connection between high frequency trading and volatility, no price manipulation is being used and there is a need for a supervision of the high frequency trading..

Patients with heart failure have a high mortality and often readmits to hospital care, due to a lack of compliance in the treatment plan. Patient education on self-care provided by nurses is important in improving patient and clinical outcomes.The aim of this study was to describe effects of nurse led interventions of patient education for elderly patients with heart failure. Literature study based on nine quantitative scientific articles. The results shows that different nurse led interventions of patient education with patients with heart failure had positive effects on self-care management, quality of life, health related quality of life and hospital care. E-mail reminder to community nurses and telephone education shows to be the most effective patient education interventions.
