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
Association’s Guide to Coat Color Genetics, was full of information about each of the types, the genetics, breeding tips, coat colors and descriptions, and the Overo Lethal White Syndrome. The
hundreds of years, it is only a matter of physical or mental violence. Black people during the history of U.S.A. face discrimination, ridicule, verbal abusement and even physical struggles from the White people.. During the time period after WWII, the conflicts between the black population and the white population rise to a higher level due to the introduction of redlining. Many newspapers, magazines, books and videos were based off on real events happening on black people due to redlining. The book
Introduction/Case Description On a cool early morning in Anytown, USA, a young couple came across a human skull near a water fountain they had stopped at to drink. Soon after they quickly alerted the authorities. Police arrived at the crime scene, and began to examine the area. They unearthed three skeletons lying side by side. The police quickly came to realize that with the large backlog of missing person cases, they would need help. Police turned to the Forensic Anthropology department to help
Surgery amid Family 's Financial Strain Wonder kid Addison Witulski has surprised her ailing 7-year old brother, Kaden Witulski, family and the community for spearheading a fundraising effort to support her brother who is suffering from Wolff-Parkinson White (WPW) syndrome. Although Kaden was born with this heart condition; in most people, the symptoms of WPM begin to manifest at age 11 to 50. According to Heart Racing, this rare electrical system disorder comes about when an anomalous accessory electrical

The World Health Organisation reports that cardiovascular disease is the number one cause of mortality worldwide. Therefore the importance of effectively diagnosing and treating cardiac conditions has become paramount. The cardiovascular system, its complexities and the various pathologies that affect it are of great interest to me. Undertaking a BSc Clinical Physiology degree specialising in Cardiology has allowed me to understand the vital role a cardiac physiologist plays in the multi-disciplinary
is generally caused by a dysautonomic syndrome, drugs, volume depletion or a combination of a variety of factors. Peripheral autonomic (sympathetic) denervation, resulting from systemic diseases can prevent needed peripheral vasoconstriction with standing, diseases such as diabetes and amyloidosis. Other diseases are Parkinsonism , and Addison’s, porphyria, tabes dorsalis, syringomyelia, spinal cord transection , Guillian–Barré syndrome, Riley–Day syndrome, surgically induced sympathectomy, pheochromocytoma
Methods to record ECG ECG: The electrocardiogram ECG or EKG` is a noninvasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart. By positioning leads electrical sensing devices on the body in standardized locations, information about many heart conditions can be learned by looking for characteristic patterns on the EKG. Explanation: In a conventional 12 lead ECG 10 electrodes are placed on the patient's limbs and on the surface
