Cardiac pacemaker Essays

defects would mean a complete change in lifestyle. This mindset changed when Wilson Greatbatch introduced the cardiac pacemaker. The cardiac pacemaker is an ingenious invention that has allowed thousands of patients with heart defects to lead normal, active lives. The pacemaker is a small apparatus that surgeons can implant into a patient’s chest to regulate abnormal heart rhythms. Pacemakers are used to treat patients with heart beats that are much faster or slower than usual. These irregular heartbeats

important organ in an organism’s body. The heart helps people get oxygen, keep the organs alive, and it keeps us alive. If this major organ fails and has problems, them that will be really bad. Although There are other major problems in the health world, cardiac problems should be prioritized by doctors. In history, it was virtually impossible to touch a heart, and open-heart surgery was just a dream.

An artificial pacemaker is an implantable electronic device that delivers a controlled, rhythmic electric stimulus to the heart muscle in order regulate the heartbeat. Functionally, a pacemaker comprises at least three parts: a electrical pulse generator, a power source and an electrode system. It is used to treat abnormal heart rhythms called Cardiac dysrhythmia or arrhythmias The development of artificial pacemaker begins with the introduction of the galvanism theory. In 1762, Luigi Galvani became

have formed into cardiac patches containing beats throughout, it is time to create a heart outline. Since the cardiospheres fused successfully, I believe that when many of these patches are made, they all can be aligned in the shape of a human heart, so the many patches can all fuse as one. To successfully do this, I will be using a technique where half of the heart will be made using an outline by covering it with these patches for them to mature into strong multicellular cardiac tissues. An outline

think that he or she has suffered cardiac arrest. If you find a person unconscious, or see him or her collapse, then you will need to check to see if he or she is responsive. Shake the person and shout to make sure that he or she is not sleeping. Pinch an infant or young child to try to wake him or her up. You should call 911 or have someone else call it. If there is another person present, then one of you can call 911 while the other one administers CPR. Sudden cardiac arrest can result in death if

Benefits of new technology Technology has grown rapidly in the last few decades and has contributed into many aspects in human life. Technology is a broad concept that has come to refer to breakthroughs in science that enables a better solution or automatic. With technology, there are many benefits that can be achieved by people. Day by day, technology made human live become easier and improved. Recent developments in technology can be seen and felt in many industries, but there are some areas

The company produce digital systems with several lines of proprietary items sold as components and had considerable success since its founding. According to the tendency of increasing of customer demand they expanded it’s business to variety of special purpose systems that applied digital techniques to computing, control tasks, information handling, and data processing

Gabriella Wolf Ally Weiss Moshe Shoenfeld Muscular System Outline Part One- About the muscular system: Muscular System Facts- Although there are over 600 muscles in your body, there are only three types of muscles- skeletal, smooth, and cardiac. The only action a muscle can perform is to contract, but the contractions help us perform millions of different things -- from pumping our blood to lifting up something heavy. The muscle receives the information from a nerve cell. Skeletal Muscles- Skeletal

A simulated heart is a mechanical gadget, about the extent of an orange, which is associated with your heart or embedded in your chest to help or supplant a debilitating heart. It might have a few valves, a system to move blood forward, and at least one chambers. At times a counterfeit heart may help your heart incidentally, until yours recoups. If so, the simulated heart will be expelled when it is never again required. All the more usually, when there is irreversible heart muscle harm and your

extending life for millions of people around the world. Medtronic employs more than 91,000 full-time employees worldwide, serving physicians, hospitals, and patients in approximately 160 countries. Medtronic’s primary products include those for cardiac rhythm disorders, cardiovascular disease, advanced and general surgical care, respiratory and monitoring

Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached. Excitability is the

The cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated

After diagnosis, medical care may include services in neurology, nutrition, gastroenterology, respiratory care, cardiac care, orthopedics, psychosocial, rehabilitation, and oral care. Prognosis Prognosis depends on the individual form of muscular dystrophy. In some cases a person with a muscle disease will get progressively weaker to the extent that it shortens life

P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons

The sliding filaments theory of muscle contraction was discovered in 1954 proposed that muscle contraction is an onset cyclic process which involves the sliding of filaments and the shortening of sarcomere. Striated muscles such as skeletal muscles contain a highly organised internal structure which allows these muscle to contract following the mechanism of sliding filament theory. Skeletal muscle contraction requires an action potential which is an electric signal sent though motor neurones towards

Smooth muscle is the muscle found in all hollow organs of the body except the heart, and is generally not under voluntary control. Cardiac muscle, the only type of muscle which does not experience fatigue, is the muscle found in the walls of the heart which continuously pumps blood through the heart. Skeletal muscle is the muscle attached to the skeleton which is the type of muscle that

There is a lot to think about when it comes to transplanting muscle fibers. Since there are fast twitch and slow twitch muscle fibers all over the body within every muscle group, one would have to extract the entire muscle. Then there is the issue with the cells of the tissue staying alive during the process of removal and transplant. However, it is possible to increase the number of muscle fast twitch muscle fibers through surgery, but one will not be able to do so without transferring over some

2 Hip Muscles and Movements The hip joint is a multi-axial ball-and-socket joint, and therefore, movements along perpendicular planes occur over a wide arch of motion, namely flexion and extension, adduction and abduction, medial and lateral rotation, and circumduction . Muscles surrounding the hip are divided into groups; each is mainly, but not only, responsible for a certain movement of the hip. The main hip flexor is the psoas muscle, helped by the iliacus, but also other muscles assist in hip

Ability of muscle to lengthen and permit the joint to move through range of motion is known as flexibility. Flexibility of a specific jointis evaluated from range of motion. Efficiency and effectiveness of human movement is depends on muscle tissue length of specific joint.1 Flexibility of a person is might be limited due to several musculoskeletal overuse injuries and significantly affect a person’s joint ability. Hamstring is one of muscle groups that have a tendency to get shorten. Predisposing

Our spine is one of the delicate organ of nervous system, as it protects the central nervous system of human body, as well as the main support for the body to stay upright. It comprises of small bones placed one over the other which provides flexibility for movement. The upper part of spine is terminated in the skull. This region where the spine is attached to the skull is called the cervical region or neck. Pain in the neck or cervical pain is one of the diseases that are found very often in
