Describe The Factors That May Affect The Heart Rate

There are many reasons on why the resting heart rate can fluctuate over time. Factors can include things like the temperature of the room we were in, or what we ate/ drank for breakfast. Also volume of liquid or chemicals in the cell can impact the heart rate.

The pulse value of a normal healthy adults will range from 60 to 100 beats per minute. When the adult exercise, get injured and affected by emotions then the pulse rate will fluctuate and get increased. Athletes, such as runners when running their heart rate ranges in 40 beats per minute due to cardiovascular

-Heart rate is the number of times a person 's heart beats per minute. When you are preforming a type of exercise that will increase your heart rate, then your heart will pump blood all around your body faster and especially to muscles that are working the most because they require the most oxygen because of the intensity they are working at. It is vital to take your resting heart rate and the normal heart rate is 60-100bpm. For example, our cardiovascular exercise was cycling on a stationary bike for 20 minutes at a reasonable pace and this will depend on whether your heart rate will increase at a slow, fast or steady rate. However, the first 5 minutes we cycled at a very fast pace in order for your heart to pump more blood all around the body and to the required muscles in order for them to work harder. But the response is that the heart rate levels off, which means that it becomes steady so that after beginning the exercise and you’re like 5 minutes into it then your heart rate will stay the same or increase by little bits unless you change the intensity all the time which is not required when doing cardiovascular exercises.

A normal heart rate at rest can range from 60-100 beats per minute (BPM) for adults. Most of the time a

In 2009, a woman by the name of Kelly Breslin died from what considered sudden death arrhythmia. She died 4 days after she had in incident at Park Avenue Bistro. Kelly’s father was the famous newspaper columnist Jimmy Breslin. There are, on average, more than 250,000 deaths each year from arrhythmia. In which most are presumed to be from your heart beating irregular and too rapid.

BMR= 66+ (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age in years) for male

The baseline heart rate of GROUP A is 84.53 , GROUP B is 84.30 and GROUP C is 85.73 showing that there was no significant difference in the baseline heart rate between the groups. After induction with propofol there was a decrease in heart rate in all the groups which was found to be significant. In GROUP A patients there was increase in the heart rate during laryngoscopy with a mean heart

The average resting heart rate (RHR) for anyone ranges from 40 to 100 beats per minute. An individual’s RHR will change due to two factors, one being your fitness levels and another being your age. The more active your everyday life style is the lower your RHR will be. The reason behind this is the heart is becoming larger as well as durable which makes the heart a lot more efficient at pumping the blood throughout the entire body. so that when the humans heart is at rest the blood will be pumped around with a single beat, resulting in less beats per minute. The healthy RHR for an 18-year-old athlete who is a male is 49-55 beats per minute (Wood, 2008).

The cardiac muscles structure are branched cells that interlink together, which creates a more tenacious structure, which can resist the strong pumping of blood through the ventricles and atria. The cardiac muscle in the heart also allows electrical charge to pass over it, so when the heart wants to pump blood; the sinoatrial node sends an electrical impulse across to the atrioventricular node which sends a wave of citation across the Purkinje tissue and down to the apex of the heart. This stimulates a heartbeat. If the Cardiac muscle didn’t allow electrical charge to pass over it, then your heart would not be able to beat and send blood to other parts in the body.

The purpose of this experiment was to ascertain the effect of intense exercise on heart rate. Heart rate is the number of times the heart contracts in one minute, meaning that an increase in heart rate will allow the heart to pump more blood to the tissues that require the oxygen carried by the blood. Heart rate can be measured by placing the fingers on either the carotid artery in the neck or the radial artery in the wrist. A resting heart rate below sixty beats per minute is lower than normal, and one above one hundred beats per minute is higher than normal. A high resting heart rate can indicate that the heart is not healthy and strong and requires more contractions to move the same amount of blood as a normal heart would with less effort (Bargar). Heart rate can be affected by a variety of factors; exercise, anxiety, and strong emotions usually increase heart rate, and sleeping generally causes heart rate to decline. This

A typical or basic EKG pattern of a cardiac cycle shows four different patterns. There is the P wave, QRS complex T wave and T wave. This cycle happens fast and it happens multiple times a day. The average resting heartbeat for an adult is 60 to 100 beats per minute.

The most of the Corporate Executives could hardly think beyond business. Moreover, business to them is no more than but profiteering. For ethics, most of them would agree with Hazrat e Ghalib who said:

The low heart rates from the exercise group and the high heart rates from the non-exercise group appeared as a result of both group’s overall fitness level. In order to achieve said results, each individual’s average heart rate was taken by feeling a pulse five times. They were then categorized in the exercise group or non-exercise group depending on whether or not they exercise for twenty minutes three times a week. There were no discrepancies in the data overall, since the results were as expected. Exercise influenced heart rate by lowering it with an inversely proportional relationship. Regular aerobic exercise is the kind of exercise that best influences heart rate and will cause heart rate to drop over time, meaning that your heart

1. What happened to the fluid flow rate as the radius of the flow tube was increased?

Exercise increases the need for both food and oxygen in the body. Heart rate increases as the arteries expand and the ventricles pump blood out of the heart. The question to be asked is how will a persons heart rate differ before and after exercise.The heart speeds up during exercise to pump extra oxygen to the muscles. An average human’s heart can beat about 42,048,000 times a day.The target heart rate zone is between 60 and 85 percent of a persons maximum heart rate. A normal resting heart rate for an adult is between 60 and 100 beats per minute. The independent variable for this lab would be the exercise being done because this is what is affecting the heart rate.
