The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
Treatment may depend on symptoms and other risk factors. Medications may include the use of beta blockers, verapamil or disopyramide. [8] An implantable cardiac defibrillator may be recommended in those with certain types of irregular heartbeat. [7]
Pacemakers are often used for slow heart rates. [6] Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. [6] Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or ...
The longer you wait to get treatment for a heart attack, the greater the damage to your heart muscle. ... heart’s electrical signals to check if your heart rhythm is irregular (too fast, too ...
Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat. Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat. The two beats are figuratively similar to two twins (hence bi-+ gemini).
A heart attack requires immediate treatment to improve blood flow to your heart, relieve your symptoms, and prevent another heart attack. Some treatment options include: Medications such as ...
They act by blocking the effects of catecholamines at the β 1-adrenergic receptors, thereby decreasing sympathetic activity on the heart, which reduces intracellular cAMP levels and hence reduces Ca 2+ influx. These agents are particularly useful in the treatment of supraventricular tachycardias. They decrease conduction through the AV node.
