- SYMPATHETIC ADRENERGIC AGONISTS are also known as? ___________ is also used at times to treat arrhythmias. This drug slows calcium from leaving the cell, prolonging the action potential and slowing conduction and heart rate. Digoxin is effective in the treatment of atrial arrhythmias. - Digoxin ____________ are used to help restore the appropriate supply-and-demand ratio in oxygen delivery to the myocardium when rest is not enough. §These drugs can work to improve blood delivery to the heart muscle in one of two ways (1) by dilating blood vessels (i.e., increasing the supply of oxygen) or (2) by decreasing the work of the heart (i.e., decreasing the demand for oxygen) - Antianginal drugs _____________ is available in an extended-release tablet form for oral use. It does prolong the QT interval, it does not decrease heart rate or blood pressure, but it does decrease myocardial workload, bringing the supply and demand for oxygen back into balance. ___________ is approved as a first-line treatment for angina or for use in combination with nitrates, beta-blockers, or amlodipine. - Ranolazine (Ranexa) PIPERAZINEACETAMIDE AGEN
