Abstract
Our design is to use a small piece of quartz embedded on the surface of the heart to act as a piezoelectric material, which will communicate with a small capsule embedded in the body. Piezoelements, as they are called, react to various mechanical stresses and electrical voltages. For example, an applied mechanical force will create voltage in response up to a four percent change in volume of the solid. Processes, such as pressure, are converted into electrical current when interacting with piezoelements. This effect is utilized in our design. As the heart beats, it compresses the crystal, creating electrical current. By utilizing this effect, we can monitor small variations in electrical output, allowing us to detect an approaching heart attack. It will be implemented into high-risk heart patients. Its versatility, practicality, and effectiveness could save lives.

The Incorporation of Piezoelectric Technology into an Integrated Cardiac Pulse Monitor
Description
present technology
The current cardiac monitors, or ECG's, are mammoth machines that require multiple electrodes to be carefully hooked to various parts of the body. There is one on each arm, leg, and six carefully spread out on the chest. They measures tiny electrical fluctuations from outside of the body. Due to the nature of the product, where it has to measure micro-fluctuations through the flesh, it is potentially inaccurate. If you compare the current results of a person's measurements to previous measurements, any changes in weight, muscle, or even damage to the chest could make it inaccurate. ECGs, or electrocardiographs, are the accepte...

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
In this article, it tells how an EKG scan is on grid paper and each small block, which is one millimeter (mm) long, represents 0.04 seconds and each larger box, which is five millimeters long, represents 0.2 seconds. On a EKG scan, the voltage of the heart is measured in millivolts (mV) along the y-axis. On the scan grid, ten millimeters is equal to one millivolt. According to this source, in order to calculate the beats per minute (BPM), one divides the number of number of large boxes between each heart beat (QRS wave) in 300 small boxes. However, that used for a more consistent and steady heart rate. For a more varied and irregular rhythm, one has to count the number of QRS waves in six seconds and then multiply that number by ten. For an example, if there are eight QRS waves, then the estimated heart rate would be 80
Heart, the key organ of the circulatory system, supplies blood to body parts by rhythmic contraction (systole) and relaxation (diastole) – the heartbeat. Heart rate is the number of beats per minute (BPM) is an important vital signs measurement for cardiovascular health and human’s wellbeing. There are many methods to measure heart rate (or pulse). One simple method is to manually count the pulse by placing finger on Radial pulse (Wrist) or the Carotid pulse (neck). The need for the ceaseless observation of the heart rate motivates for the invention of heart rate monitors. Another essential factor is the Oxygen saturation (So2 or SpO2), the oxygen concentration in hemoglobin. As the name says, we need oxygen to survive. To achieve this, the technique Pulse oximetry is employed. Pulse oximetry produces a graph, called Plethysmogram.
To improve the accuracy of the results, the same person should conduct all of the experiments as different people may count the heart rate at different speeds, leading to variation in the results.
What I wanted to talk about today is this life save device called a automated external defibrillator. It has become the number one way to resuscitate a person who has had a cardiac arrest unwitnessed by emergency medical services and who is still in persistent ventricular fibrillation or ventricular tachycardia. Many people have played a big role in creating this device to become more efficient, smaller and easier to use for the general public. Here are just to name a few that played a part in the creation for this device: Claude Beck, James Rand, Paul Zoll, and Frank Pantridge. The first use of a defibrillator on a patient was in 1947 on a 14 year old boy. Claude Beck was performing a open-chest surgery when the boy went into fibrillation. Beck manually massaged his heart for 45 minutes until the arrival of the defibrillator. The defibrillator he used during surgery was made by James Rand and had silver paddles the size of large teaspoons. In 1956, Paul Zoll performed the first successful external defibrillation with a more powerful defibrillator. A major breakthrough in emergency medicine occur in 1965. At the time a majority of coronary deaths occurred outside of the hospital setting since defibrillator required a main power source and were only available in hospitals it made them pretty much useless in saving lives outside of a hospital setting. Frank Pantridge often referred to as the Father of Emergency Medicine, made the first portable defibrillator in 1965. This device was power by a car battery and weighted approximately 70 kg (155 lbs). By 1968 he was able to create a defibrillator that was safer to use and only weighted 3 kg (6-7 lbs). It was argued that their was a possibility of misuse of the device if given to a unt...
The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside natural heart abnormalities are those induced by chemical substances. The electrocardiogram is useful in showing how these chemicals adjust the electrical impulses that it induces.
Oxygen is vital to a beating, healthy heart because it is needed to perform cellular respiration in order to pump the blood. When there is no oxygen being transported to the heart, the heart cannot pump blood, and eventually after being inactive, the heart tissue dies . This results in a heart attack. Heart attacks can be diagnosed before it is too late. One method of diagnosis is through a blood test. Blood tests are capable of sorting through the material found in blood, and if heart cell contents are found in the specimen, a heart attack can be diagnosed. If the levels of the cell contents are higher, this signifies that the heart attack is more severe. Another method of diagnosis is an electrocardiogram (ECG). An ECG measures the rhythm of the heart in order to detect defects. There are many other strategies that are used by doctors in order to diagnose a heart attack, such as chest x-rays, stress tests, tilt table tests, and echocardiograms, to name a few. A myocardial biopsy involves looking at the heart cells, and is accomplished by collecting a sample of heart cells from the patient. If the results are positive, a heart attack is diagnosed. A heart MRI involves looking at images of the heart in order to detect heart failure. The doctor uses the images to look for disorders in the structure of the

This condition can be treated various ways depending on “the type and frequency of arrhythmias, associated symptoms…, and the presence of structural heart disease” (Cleveland Clinic, 2014). Some patients may not need treatment at all, since they show not symptoms, since sometimes this condition can be naturally eliminated over the first year of life, but may still be required to have regular schedule appointments with the physician so the patients can be monitored. If symptoms are prevalent, the different treatment methods include a pacemaker, defibrillator, surgery, and medicine.
When expecting a baby, parents hope their child is born with ten tiny toes, ten little fingers, the perfect little button nose, and a smile made out of gold. Most may not think about the vital development and intricacies of their baby's heart. Once the baby is born, parent’s uncertainties may be laid to rest as technology has provided the world with multiple means of being able to detect the most miniscule of abnormalities. One of which includes the electrocardiogram as this device is able to monitor and record the electrical impulses the heart is generating. With the addition of this device, a doctor can detect abnormal rhythms in the heart. By using machines such as the electrocardiogram, examining heart murmurs, and aortic stenosis, the parent will be able to be informed and prepared for any ailments of the heart a child may develop.
Lidwell and Edgar H. Booth invented the first pacemaker. It was a portable device that consisting of two poles, one of which included a needle that would be plunged into a cardiac chamber. It was very crude, but it succeeded in reviving a stillborn baby at a Sydney hospital in 1928. The decades that followed, inventors came up with increasingly sophisticated versions of the pacemaker. However, these devices; which relied upon vacuum tubes; remained heavy and bulky, affording little or no mobility for patients. Colombian electrical engineer Jorge Reynolds Pombo developed a pacemaker in 1958 weighed 99 lbs and was powered by a 12-volt auto battery. Surgeons at the Karolinska Institute in Sweden were the first to place a fully implantable device into a patient in 1958. Rune Elmqvist and surgeon Ake Senning invented this pacemaker, which was implanted in the chest of Arne Larsson. The first device failed after three hours, the second after two days. Larsson would have 26 different pacemakers implanted in him. He died at the age of 86 in 2001, outliving both Elmqvist and Senning. In the world there are many heart attacks and as people grow they can get abnormalities in there heart(Medlineplus). When someone 's heart stops working it can be fixed with a pacemaker, it makes the heart beat properly. The artificial pacemaker is a wonder of modern science. A small, implantable device that regulates a human heartbeat through electrical impulses have saved millions of lives. The development of this vital medical device owes much to the advances in electronics and communications brought about by the Space Age.Pacemakers may be used for people who have heart problems that cause their heart to beat too slowly. A slow heartbeat is called Bradycardia two common problems that cause a slow heartbeat are sinus node disease and heart block. When your heart
With the use of heart rate monitors students will become knowledgeable of how and where they should be with their level of fitness against the fitness level of other students. “Heart monitors provide a way to measure improvements in fitness levels, below maximum effort, and recovery.
Vital signs are very important measurements that should be done with little to no errors. As humans, we often make silly mistakes here and there, but as a medical assistant we must pay close attention to every detail. When we first meet a patient, start with small talk to see how the person is feeling. If we can tell that the patient is angry, or seems to be in a bad mood we could expect to see an elevated pulse, respiration, and blood pressure. If we can calm the patient down, their new vitals would be more accurate. Errors happen all the time with anything in life. Contributing factors in inaccurate vital sign readings include:
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
Pacemakers are an electrical pulse regulatory mechanism, that helps create well balanced heart beats in patients in need. Pacemaker monitoring in the past has been limited to Physician visits, and emergent visit to the hospitals. Proper pacemaker monitoring with real-time implications leaves new insight and advancement within the medical field; while delivering real-time possible life saving patient information to appropriate personnel.
