Essay on How Ekg Works

Heart rate anticipatory response – this is where the heart rate starts to automatically increase before you start to exercise. The heart rate is able to increase automatically by chemical hormones, the hormones are adrenaline and noradrenaline. These hormones are found inside the brain. The reason the heart rate increase before exercise is because it prepares the muscles for exercise, the reason it prepares the muscles for exercise is because by the heart rate increase the more oxygen is getting to the muscles there fore they will not be needing a such a large oxygen supply all at once. It doesn’t only supply oxygen it supply’s nutrients, the supply of nutrients also provides energy and helps to repair the muscles after exercise. By the heart rate starting to increase gives the heart a head to start pumping hard this enables the heart to not have as much stress on it.

The EKG is read by a doctor or specialist, such as an internist, family medicine doctor, electrophysiologist, cardiologist, anesthesiologist, or surgeon. The doctor will look at the pattern of spikes and dips on your EKG to check the electrical activity in different parts of your heart. The spikes and dips are grouped into different sections that show how your heart is working

The anticipatory response is where the heart rate increases at the beginning of an exercise. By increasing our heart rate, our body begins to supply oxygen and nutrients through your arteries to the working muscles. The heart rate can be changed by chemicals and neurotransmitters called adrenaline and noradrenaline which are released and found in the brain. These neurotransmitters are chemicals that are found and released in to the brain which allows an impulse from one nerve cell to another. These chemicals notifies the heart to get ready before exercising and this results in your heart will start to beat much more beats per minute and an increase in the heart rate.

The heart is a muscle that is divided into four chambers. The top of the heart has two atria while two ventricles are located on the bottom. When the heart is healthy, the heartbeat will begin in the right atrium. The right atrium will send an electrical signal across the heart spreading throughout the atria to the AV node, then to the ventricles. This electrical impulse, occurring about 60 to 100 times per minute, causes the heart to contract. Each contraction equals a single heartbeat. According to the Human Diseases and Conditions article , under some conditions, almost all heart tissue is capable of starting a heartbeat, or becoming the pacemaker. A dysrhythmia occurs when:

Assess the ECG and, using a systematic approach, describe and interpret the ECG. Discuss the aetiology and pathogenesis of coronary atherosclerosis and myocardial ischaemia in your answer.

During these experiments, the subjects that were used were animals that showed signs of heart deformities. These animals were then given health assessments, as well as electrocardiograms, phonocardiograms, and thoracic roentgenograms (Detweiler and Patterson 481). The heart gives off electrical waves that flow from top to bottom each time that it pumps. Electrograms are tests that are conducted in order to test the electrical activity within the heart. By testing this, it gives a clear view of heart conditions that are not easily noticed. Phonocardiograms are used to concentrate mainly on the sounds of the heart. What this does is allow the scientist to listen for abnormal noises coming from the heart as well as for murmurs as well.

Graph 1 highlights the sudden increase in heart rate immediately after exercise, and the gradual decrease afterwards. The heart rate peaked at an average of 148 beats per minute (BPM) immediately after the exercise, which was an 85 BPM difference to its resting rate. Furthermore, the results showed that the heart rate decreased over time and in just ten minutes, returned to its resting rate. During exercise, heart rate increases so that more blood can be pumped to muscles at a faster rate. However, less effort is needed

Dr. Smith had ordered The ECG due to Mr. Adam complains about chest pain and pain radiating to his left arm and back. The ECG supports Mr. Adam’s diagnosis of MI because according to his ECG result, the ST segment does not look normal and it is raised or elevated. The ST segment is the time between the end of the QRS complex and the start of the T wave which represents the period of zero potential between ventricular depolarization and repolarization. The ST segment is used as baseline reference by both the PQ and TP segments. The PQ and the TP are diastolic potentials.

The first accurate recording using an electrocardiogram (ECG) occurred in 1895. Willem Einthoven was the first person to create an ECG that accurately depicted the recording of the heart’s electrical currents (Jenkins, 2011). Einthoven “was awarded the Nobel prize in Physiology or Medicine”(Nobelprize, 2014, p. 1) in 1924 for the discovery of the electrocardiogram (Nobelprize 2014). Not only did he configure the machine but he also created the deflections. They are the labels of the points on the wave created by the electrocardiogram, PQRST, are the letters at each point or curve on the wave . Einthoven was the sole founder of the ECG but without the help of previous scientist Einthoven would have never discovered the electrocardiogram

The impact that exercise has on your heart rate is that it speeds it up. I feel like exercising is good for your heart because it keeps it working. We started our physio assignment on the 15th of june and it also ended on the 3rd of july. The first observation I made was that for 15 seconds my heart beat 14 times when resting. My heart beat after running the course was beating at a rate of 24 for 15 seconds. The following day my resting heart beat was 14 beats for 15 seconds and my heart after running was at 30 beats for 15 seconds. The 3rd day my resting heart rate was still 14 beats for 15 seconds my heart after running was also 30 beats for 15 seconds. About a week later my resting heart rate went up to 15 beats for 15 sec and after the

The hypothesis states that if the intensity of exercise increases then the heart pulse and breathing rate will increase when the treadmill incline, time interval between and during sets and equipment used are all kept constant. When humans exercise, the heart speeds up to pump more oxygen into the muscles and this is why the breathing and heart rate increase. The heart rate automatically increases as we exercise, due to the circulatory system, as blood needs to flow around the body faster.

One of the wave forms is the QRS wave complex. The QRS wave complex consists of three waves; the Q wave, the R wave, and the S wave. The QRS complex represents ventricular depolarization or systole. Each individual wave in the QRS complex represents a different deflection. The Q wave is the negative deflection that occurs before the R

ECG, which stands for Electrocardiography, is a common cardiac test prescribed to heart patients. Also referred to as EKG, the test is performed to record the electrical activity of the heart over a period of time. The process uses electrodes to detect the tiny electrical change on the skin that are arisen by the heart muscle depolarizing with each heartbeat.

ECG Feature Extraction acts as a significant role in diagnosing lots of the cardiac diseases. One cardiac cycle in an ECG signal includes of the P-QRS-T waves. This feature extraction technique determines the amplitudes and intervals in the ECG signal for subsequent analysis. The amplitudes and intervals value of P-QRS-T segment decides the operation of the heart of every human. Recently, numerous research and techniques have been presented for analyzing the ECG. A large number of possibilities have been introduced about which features to utilize to describe the EEG signals. Finding the right feature combinations is a significant task. However, if all features found in the literature were introduced, the number of features considered too large

The Patients assessment tool is the equipment, which are used to treat the patients either outdoors or inside hospital or in any medical centers. An Electrocardiogram (ECG) monitor is a simple diagnostic test to tell about the heartbeat by placing some electrodes on our body. ECG monitor also provide all the heart related problems and the functioning of heart. An ECG monitor is a simple painless noninvasive test that can be performed in virtually any clinic, doctor office or medical facility.
