Heart rate depends on several factors such as hormonal, neurogenic, physical activity, blockage or stenosis in the vessels, body temperature etc. In fact, anything which affects the homeostatic balance of the body will have some effect on the heart rate. If the body is cold, the rate will increase to drive more heat in the blood to the places where it can sustain the life of the organism. If there is blood loss or severe hemorrhage, the rate will increase to send life saving blood to those places to sustain life. Increase in the heart rate is generally called sinus tachycardia. Decrease in the rate is called- Bradycardia. If there is blockage or stenosis the rate will also increase. rapid exercise or exertion will also cause increase. The hormone adrenalin from the adrenal glands will also speed up the rate. Bood circulation is the vital way that life is sustained in the organism. Cessation of blood flow will cause lack of oxygenated blood to the vital organs and will result in death first to the heart muscle and then to the brain. Oxygenated blood from the heart goes first to the heart muscle, then to the rest of the body. I have put all this complex human physiology in its simplistic form for all to understand.

Cardiac catheterization
Blood pressure.
It indicates that someones body has an increased pulse rate then you will have a increased heart rate as well this eventually leads to high blood pressure because the blood flows more powerful through the body.
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
Gout is not contagious. gout is caused by increased uric acid in the blood stream.http://uimc.discoveryhospital.com/main.php?id=663
Activity increased vasodilation because increased activity requires a better blood supply. Resting decreases the dilation of the blood vessels because less blood is needed for oxygen and energy.

When you exercise, your breathing rate increases to take in more oxygen and give out carbon dioxide. Your heart rate increases so that the heart can pump blood containing more oxygen and digested food around your body faster. This is to produce more energy for your body.
Extra physical activity tend to have increased blood loss during menstrual periods. So women should not go for exercise during menstrual period.
total peripheral resistance will decrease because of vaso dilation of local arterioles that are supplying the active muscles i.e,skeletal muscles. and blood pressure will increase for two reasons: increased cardiac output resulting from increased pumping activity of heart. because of vasoconstriction of arterioles every where else in the body
Fluctuations in an individual's blood pressure are normal during the course of a day. When one awakens, the blood pressure is lower as a result of the decreased metabolism and physical activity during sleep. As metabolism and activity increases during the day, the blood pressure rises.

Body cells get oxygen and food from blood. So, faster breathing causing increased oxygenation and increased heart rate cause greater blood flow during exercise.
Selective redistribution of blood is an important factor in increasing performance during physical activity arteries dilate and constrict during this process
It depends more on how active a person is than their actual weight. More activity causes increased blood flow carrying nutrients, oxygen and white blood cells to injuries increasing healing speed and efficiency. An overweight person may have less blood flow because of excess fat and lower activity which could effect healing. A person weighing more due to increased muscle would also have increased blood supply to these muscle tissues which would also cause increased healing.
Warming up (light exercise before more strenuous exercise) results in vasodilation of the skeletal circulation. This causes increased blood supply to the skeletal muscle to satisfy the oxygen and nutrient demands of the increased metabolic activity of the muscle during exercise.
