Before the study, scientists had not been able to formulate an effective way to identify the disease, known as Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), until it progressed to deadly stages...
Most earlier mechanical hearts - such as the seminal Jarvik 7 and other ventricular assist devices - were not designed to replace diseased hearts entirely, but to assist impaired function and bridge heart patients to transplant. Other total artificial hearts, meanwhile, such as the U.S.-developed AbioCor and a prototype being tested by MagScrew, have not successfully modulated beating and pulse according to the physical needs of the host...
...need to measure the dopamine increase. She moved to pick up Ardman's chart, which listed his weight, but just then the simulator's blood pressure dropped radically, prompting Monica to make the same error that Thomas had made: she went for epinephrine. After the drug sent Ardman into ventricular tachycardia, Monica was fast enough to shock him with the defibrillator. But this time poor Mr. Ardman died before the experiment ended. The expert had killed Ardman even faster than the novice...
...Wood’s study tracked the hearts of 60 marathoners using echocardiography, which produces an image of the heart by means of sound waves. That method, along with blood sample tests, revealed that under-trained marathon runners suffered from a host of abnormalities—including decreased right ventricular function and elevated levels of two enzymes linked to heart stress. These negative symptoms were much less pronounced in those who ran at least 45 miles per week before the marathon according to the study. For example, under-trained marathoners exhibited levels of one stress-linked enzyme that were nine...
...Doctors at the Corpus Christi hospital will be watching to make sure Mr. Whittington does not develop ventricular fibrillation, a more serious type of irregular heartbeat that can be fatal within minutes. "It will stay a minor problem as long as the arrhythmia stays under control, the heart muscle hasn't suffered permanent damage, he doesn't have a further ongoing heart attack, and there's no fluid building up around the heart," says Dr. Soumi Eachempati, a trauma surgeon at New York Hospital in New York City. Assuming nothing else goes wrong, however, Whittington should be able...
