Digitalis digitalis. As a result of increased contractility, stroke volume is increased. Ultimately, digitalis increases cardiac output (Cardiac Output=Stroke Volume x Heart Rate). This is the mechanism that makes this drug a popular treatment for congestive heart failure, which is characterized by low cardiac output. Digitalis also has a vagal effect on the parasympathetic nervous system, and as such is used in re-entrant cardiac arrhythmias and to slow the ventricular rate during atrial fibrillation. The dependence on the vagal effect means digitalis is not effective when a patient has a high sympathetic nervous system drive, which is the case with acutely
Mountaineer Power Plant that coal now comes via barge on the Ohio River to an elaborate coal unloading and storage facility.The other portion of coal comes from Big River Mining. An underground coal mine right across the street from the plant. It is mined, cleaned, processed, and shipped by a belt line across the street to the power plant. This single boiler, dual turbine plant produces enough energy to power a city approximately the size of Columbus, Ohio. The plant is connected to the grid by 765 kilovolt transmission lines (the highest rated voltage used in the United States). The location of the
