Heart Rate Investigation
Aim:
To discover if there is any link between the amount of exercise taken
to the rise of a persons heart rate.
Prediction:
I predict that as the amount of time you exercise goes up so will your
heart rate. But after a certain amount of time your heart rates rate
of increase will slow down and eventually level out and stay the same,
until you slow down or stop exercising.
This is because the more you exercise the more energy your body will
need. Oxygen is pumped around the body in the blood, the heart pumps
the blood around the body so you have a higher heart rate while or
shortly after exercise as the heart is working harder pumping the
blood around the body.

Method:
· Start by setting up all the apparatus and put the trainers on and
tie securely.
· Take your resting heart rate. Lie down as you take it as you are
most rested lying down take it for 15 seconds and times it by 4,so
that it is the amount of beats per minute. Doing this will be more
accurate than taking the heart rate for 60 seconds at one go. As you
would be more likely to loose count of the number of heartbeats.
· Use the stopwatch to time 1,2,3,4 and 5 minutes of continuous
step-ups. After each different length session of step ups take your
There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the atria, and the QRS complex represents ventricular activity. This is why the PR interval shows the signal delay from the AV node. There are three degrees of severity, and if the delay is greater than .2 seconds it is classified as first degree. Second degree is classified by several regularly spaced P waves before each QRS complex. Third degree can be shown by P waves that have no spacing relationship to the QRS complex. Another type of blockage is bundle branch block. This is caused by a blockage in the bundle of His, creating a delay in the electrical signals traveling down the bundle branches to reach the ventricles. This results in a slowed heart beat, or brachycardia. On an EKG reading this is shown as a prolonged QRS complex. A normal QRS is about .8-.12 seconds, and anything longer is considered bundle branch block. Another type of abnormal EKG reading is atrial fibrillation, when the atria contracts very quickly. On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays
The first participant measured her pulse rate for 30 seconds before starting the exercise. Her pulse rate was calculated to determine the number of beats per minute. She then stepped on the platform (up and down) and continued at a slow pace for 3 minutes. After three minutes of the exercise, she measured her pulse rate every minute to determine her recovery time. This process was repeated until her pulse rate returned to normal.
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
Valerie Bettis created the solo dance, The Desperate Heart, in 1943. The dance was created with a dramatic touch, depicting the feeling of lost love. Bettis set this piece with the objective of analyzing lost love in a back and forth matter. This goal was achieved throughout Bettis’ work with the help of music, lighting, attire, vocals, imagery, and choreography. The vocals at the beginning and end of the dance are a poem written by John Malcom Brinnin also named The Desperate Heart. My analysis is based off of Bettis’ solo performed by Brook Notary at a concert on June 11, 1993.
The Tell Tale Heart and Greasy Lake have interesting characters to analyze. Edgar Allen Poe’s Tell Tale Heart has an eerie and dark tone that Poe’s literary work is known for. Greasy Lake by T.C. Boyle starts out with hardcore yet naïve teenagers looking to had a good time. However, their naivety and immaturity will led them into a very bad situation.
Firstly we lay them on the back to get the resting heart rate and we
Pause the beep test on your laptop after level 1 finishes. 7) Get timer ready to time 5 seconds after the level and another timer to measure 30 seconds. 8. 5 seconds after the beep goes, the subjects must measure their heart rate by placing their index and middle fingers under their right lower jaw and finding their pulse (move your fingers around a little to find the clearest pulse possible). Once you have found your pulse, count how many times you feel your pulse for 30 seconds and multiply that answer by 2 to give you beats per minute.
Arrhythmia I am doing my report on Arrhythmia. It affects the cardiac muscle, the heart. Arrhythmia causes three types of problems. It causes the heart to pump too slowly (bradycardia), it causes the heart to pump too fast (tachycardis), and it causes the heart to skip beats (palipations).
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
The two major things that will help an athlete while measuring the cardiovascular drift are progression and hydration levels. The heart rate of an athlete working hard during a workout should be no more than their maximum heart rate which is found by, if you’re a female take 226-age, if you’re a male take 220-age. If while doing a workout the maximum heart rate is exceeded by too much it may be necessary to take a break or slow down greatly. This may also help with traking the hydration of an athlete. If an athlete stays hydrated their core temperature will stay regulated which means they won’t sweat as much, which also means the heart won’t be under as much stress while transporting the oxygenated blood throughout the body to the
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.

There are 2 types of breathing, costal and diaphragmatic breathing (Berman, 2015). Costal refers to the intercostal and accessory muscles while diaphragmatic refers to breathing using your diaphragm (Berman, 2015).It is important to understand the two different types of breathing because it is vital in the assessment of the patient. For example, if a patient is suing their accessory muscles to aid in breathing then we can safely assume that they are having breathing problems and use a focused assessment of their respiration. Assessing respiration is fairly straightforward. The patient’s respiration rate can be affected by anxiety so a useful to avoid this is to check pulse first and after you have finished that, while still holding their pulse point, check their respiration rate. Inconspicuous assessment avoids the patient changing their breathing because they know they are being assessed which patients can sometimes do subconsciously. Through textbooks and practical classes I have learned what to be aware of while assessing a patient’s respiratory rate. For example; their normal breathing pattern, if and how their health problems are affecting their breathing, any medications that could affect their respiratory rate and also the rate, depth, rhythm and quality of their breathing (Berman, 2015). The only problem I found while assessing respiration rate was I thought it seemed a bit invasive looking at the
