Digoxin is one of the oldest medications used in the field of cardiology. It works by increasing myocardial contractility, increasing stroke volume and blood pressure, reducing heart rate, and somewhat extending the time frame of the contraction. [5] Digoxin is taken by mouth or by injection into a vein. [4]
High blood pressure, also known as hypertension, is a common health issue, affecting nearly half of adults in the United States (48%).. When an individual is diagnosed with high blood pressure ...
High blood pressure is caused by the force of blood flow in the arteries being too high. The DASH diet includes heart-healthy foods that lower blood pressure. 21 foods that lower blood pressure ...
Oatmeal is capable of lowering both your systolic and diastolic pressure (the numbers that make up your blood pressure reading). A study reported in a 2002 edition of “The Journal of Family ...
In contemporary medicine, digitalis (usually digoxin) is obtained from D. lanata. [27] [28] It is used to increase cardiac contractility (it is a positive inotrope) and as an antiarrhythmic agent to control the heart rate, particularly in the irregular (and often fast) atrial fibrillation.
Kidney function gradually decreases as someone ages. The elderly are also likely to be underweight. In addition, these older people tend to be dehydrated and be taking other medications. These factors increase the likelihood of developing side effects of digoxin and digoxin toxicity. Often lowering the dose is considered by the prescriber. [6]
By increasing the concentration of intracellular calcium or increasing the sensitivity of receptor proteins to calcium, positive inotropic agents can increase myocardial contractility. [7] Concentrations of intracellular calcium can be increased by increasing influx into the cell or stimulating release from the sarcoplasmic reticulum.
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. [1] Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias ; however, their relative toxicity prevents them ...
