Mark Cowley Lidwill
Mark Cowley Lidwill (1878-1969) was a medical pioneer in Anesthesia, anaesthesiology and cardiology. Supported by physicist Edgar H. Booth, he invented the pacemaker. Early life Born in Cheltenham, Cheltenham, England on 7 April 1878, Lidwill emigrated with his parents to Melbourne, Melbourne, Australia, in 1894 and later graduated with honours in medicine from Melbourne University (MB 1902, BCh 1903), and as MD in 1905. Invention of pacemaker Lidwill discovered that by using electricity he could stimulate muscles. He then went on to discover he could use electricity to set the pace of a sick heart. In 1926, Lidwill was working at the Crown Street Women's Hospital in Sydney where he resuscitated a newborn baby with an electrical device. Lidwill's method was to put a needle into the heart to administer 16-volt impulses via the apparatus he had invented. Lidwill’s knowledge and expertise extended not only to his invention of the cardiac pacemaker but to the design and manufa ...

Anesthesia
Anesthesia (American English) or anaesthesia (British English) is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise require physical restraint in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * ''General anesthesia'' suppresses central nervous system activity and results in unconsciousness and total lack of Sensation (psychology), sensation, using either injected or inhaled drugs. * ''Sedation'' suppresses the central nervous system to a lesser degree, inhibiting both anxiolysis, anxiety and creation of long-term memory, ...

Cardiology
Cardiology () is the study of the heart. Cardiology is a branch of medicine that deals with disorders of the heart and the cardiovascular system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a sub-specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery. Specializations All cardiologists in the branch of medicine study the disorders of the heart, but the study of adult and child heart disorders each require different training pathways. Therefore, an adult cardiologist (often simply called "cardiologist") is inadequately trained to take care of children, and pediatric cardiologists are not trained to treat ...

Pacemaker
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, thus regulating the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist to select the optimal pacing modes for individual patients. Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of impulses. A specific type of pacemaker, called an implantable cardioverter-defibrillator, combines pacemaker and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Marlin
The black marlin (''Istiompax indica'') is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans approximately between 40 degrees North and 45 degrees South, while in some instances venturing into more temperate waters. Reaching lengths of over , It is one of the largest marlins and also one of the largest bony fish. Marlin are among the fastest fish, but speeds may be exaggerated in popular media, such as reports of . A 2016 study estimated maximum swimming speeds from muscle contraction times, which in turn limit the tail-beat frequency; the study suggested a theoretical upper limit for the black marlin's burst speed of . Black marlin are fished commercially and are also a highly prized game fish. Black marlins were known to drag ancient Maldivian fishing boats for very long distances until the marlins tired; it would take many hours for the fishermen to row or sail back home. Due to the common misidentification of large billfish such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
