Heart Rate Experiment

The app only runs through wearables like Pebble, Android Wear, and Apple Watch. It monitors the heart rate and the body movements of a person sleeping.

2. Physiological state in defined as “the condition or state of the body or bodily functions”. This can be measured when we perform our observations. By measuring a patient’s respiratory rate, oxygen saturations, peak flow (in asthma patients), pulse rate, systolic and diastolic blood pressure, core temperature, blood sugar, pupil reaction and Glasgow coma scale. All these combined measurement can give us an insight into the patient’s health or Physiological state.

* Four heart rates were recorded in both water and caffeine solution so that an average could be produced.

The Changes of Heart Rate of Students during Human Dive Response when Resting and Submerged

An dysrhythmia of the heart is an irregular heartbeat rhythm. Ventricular tachycardia is an dysrhythmia in which the lower chambers of the heart, the ventricles, beat unusually fast.

The respiratory monitor measured baseline respiration for a minute. Respiratory rate was also measured by the respiratory monitor throughout the entire experiment. After initial respiratory rate had been measured for about 30 seconds, researchers established a baseline heart rate range using the pulse oximeter. This was done by recording maximum and minimum heart rates within a period of 30 seconds. Since the site of the experiment had abundant background noise, silence could not be used as the control variable. Therefore, white noise was used as the control instead. The subjects listened to “Original White Noise” by White! Noise using Sony MDR7506 Dynamic Stereo Headphones. The subject was instructed to pedal at a rate between 8 and 10 mph and was supervised by an experimenter to ensure that the participant stayed within the proper pedaling speed range. As the participant pedaled, the researchers changed the resistance on the stationary bike between resistance levels 8 and 11 to make sure that the participant’s heart rate was within the preferred range. Subjects were monitored to ensure they had the heart rate ranges of 55-65% of his or her age-predicted heart range. The subject pedaled for two minutes,

I dropped you a line while you were at the CTCA Centennial Purina Event so, how did everything go? I hope you and Helen had plenty of time to catch up and that your return home went well.

When I merged to Chapter 6 from Chapter 5 my feelings went from being very sympathetic towards being very antipathetic. One of the biggest reasons why my feelings changed was the interaction between the creature and William. Which showed the creature strangling William to death showed by the image on page 13, showing William on the ground with two letter x's over his eyes resembling his death. However, the quote itself better explains more as it states "My enemy is not impregnable this death will carry to despair to him, and a thousand other miseries shall destroy him", Therefore given the idea that the creature did, in fact, kill him.

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Research has shown that deep breathing exercises can induce an increase in heart rate (Sroufe 1971) because heart rate is also directly correlated with breathing (Egri 2012). When breathing in, heart rate will increase; and while breathing out, heart rate will decrease (Egri 2012). Blood pressure can be reduced with slower breathing (Joseph et al. 2005). An article in the Journal of Human Hypertension showed that doing breathing exercises over a period of time can lower both systolic and diastolic blood pressure (Grossman et al. 2001). The hypothesis in this experiment is that blood pressure and heart rate will be affected by a deep breathing exercise. The null hypothesis was that heart rate and blood pressure will be unchanged while performing a deep breathing exercise. This experiment is significant because it could help people in times of stress or anxiety/panic attacks to learn ways to calm their heart rate and blood pressure down so they may feel better. Being the most common mental illness in the United States and 18% of Americans living with it, research aiding recovery of panic attacks would be extremely useful to the public (Kessler et al. 2005).

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

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

Pacemaker cells rhythmically produce electrical signals that will traverse through the heart and ultimately excite contractile cells. These electrical currents produced by pacemaker cells are large enough to be detected by recording electrodes on the skin, and thus an electrocardiogram (ECG) can be created. An ECG is made of three distinct components: the P-wave produced by atrial depolarization, the QRS complex produced by ventricular depolarization, and the T-wave produced by ventricular repolarization. Because the QRS complex has the largest amplitude and is easiest to detect, it was the ECG component chosen to be measured throughout the present experiment. Additionally, the rate at which QRS complexes are produced by the pacemaker cells in a given interval can be used to determine heart rate. Like the electrical activity of the brain, cardiac activity can vary in response to a multitude of different factors such as autonomic activity. In attempt to further explore the correlation between autonomic activity and emotion evoked by musical listening suggested by previous studies (Iwanaga et al., 2005; Orini et al., 2010), we measured heart rate and QRS complex amplitude as various music genres were being listened to. These experiments were conducted in order to better understand the physiological properties and mechanisms used by the human body to influence cardiac activity in response to various music genres being listened
