![]() Examples of heart rhythm controlling medications include: Sodium channel blockers These drugs allow the heart to reset into a normal rhythm. A-fib disrupts this signaling pathway, leading to an abnormal heart rhythm. Electrical signals help the heart contract in a coordinated way. Experts may also refer to this as pharmacological or chemical cardioversion. These types of drugs attempt to restore the heart rhythm to normal. Potential side effects of digoxin include: Alternatively, they may suggest using digoxin in addition to these drugs if a person requires a further reduction in their heart rate. A doctor may prescribe digoxin if a person is unable to tolerate beta-blockers or CCBs. It influences the electrical activity in the heart, increasing the force of contraction while slowing conduction to decrease heart rate. Digoxinĭigoxin is a drug that can help manage heart rate. ![]() Side effects from CCBs are rare, but they can include:Įxamples of calcium channel blockers include diltiazem hydrochloride and verapamil hydrochloride. CCBs reduce the amount of calcium that can enter cardiac muscle cells and blood vessel walls, which helps lower blood pressure and slow a person’s heart rate. Calcium plays a vital role in enabling muscle contraction and allowing the heart to pump blood around the body. However, some individuals may still experience side effects, such as:Ĭalcium channel blockers (CCBs) can increase blood flow and oxygen to the heart. Generally, people are able to tolerate beta-blockers well. ![]() In doing so, they help blood vessels relax, easing the passage of blood. They can block the release of epinephrine and norepinephrine, which would otherwise cause a rapid heartbeat and heart palpitations.īeta-blockers can also reduce the production of angiotensin II. Examples of heart rate-controlling medications include: Beta-blockersīeta-blockers, also known as beta-adrenergic blocking agents, are a group of drugs that block the action of certain hormones that can affect the heart rate. Typically, they slow the heart rate by blocking irregular electrical signals in the atria, which prevents their transmission to the ventricles. These medications, which are known as anti-arrhythmic drugs, help control heart rate. Possible side effects of antiplatelets include:Įxamples of antiplatelets include clopidogrel bisulfate and aspirin. A person should not start or stop aspirin without first consulting a doctor. As such, a doctor may only recommend antiplatelets for individuals with a high risk of A-fib or other cardiovascular events. However, a high number of platelets can result in unnecessary clotting, which can increase the risk of a stroke. Platelets are small fragments of cells, and their main function is to stick to the lining of blood vessels and form a blood clot to help stop or prevent bleeding. Possible side effects of anticoagulants include:Īntiplatelet drugs describe medications that prevent platelets, also known as thrombocytes, from sticking together. ![]() By preventing these substances from working correctly, anticoagulants can help reduce the formation of blood clots. The formation of a blood clot relies on substances called clotting factors undergoing a coagulation cascade. Examples of drugs that help prevent blood clots include: AnticoagulantsĪnticoagulants are a group of medications that reduce the body’s ability to form blood clots by interrupting the blood clotting process. As such, people may receive drugs known as blood thinners to prevent blood clot formation or to treat an existing blood clot. If these blood clots enter the bloodstream, they can lead to a stroke.
