2. Antiarrhythmic agent - Wikipedia

   en.wikipedia.org/wiki/Antiarrhythmic_agent

   Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.

3. Tachycardia - Wikipedia

   It may be difficult to determine the rhythm's regularity when the rate exceeds 150 beats per minute. Depending on the patient's health and other variables such as medications taken for rate control, atrial fibrillation may cause heart rates that span from 50 to 250 beats per minute (or even higher if an accessory pathway is present). However ...

6. Drug-induced QT prolongation - Wikipedia

   en.wikipedia.org/wiki/Drug-induced_QT_prolongation

   Class III antiarrhythmic drugs are potassium channel blockers that cause QT prolongation and are associated with TdP. Amiodarone. Amiodarone works in many ways. It blocks sodium, potassium, and calcium channels, as well as alpha and beta adrenergic receptors. Because of its multiple actions, amiodarone causes QT prolongation but TdP is rarely ...

   This makes it different from other conditions that generally cause a fast heart rate. The onset of POTS can sometimes begin after other major health events , like pregnancy, surgery, or viral illness.

8. Arrhythmia - Wikipedia

   en.wikipedia.org/wiki/Arrhythmia

   Several groups of drugs slow conduction through the heart, without actually preventing an arrhythmia. These drugs can be used to "rate control" a fast rhythm and make it physically tolerable for the patient. [citation needed] Some arrhythmias promote blood clotting within the heart and increase the risk of embolus and stroke.

9. Cardiotonic agent - Wikipedia

   en.wikipedia.org/wiki/Cardiotonic_agent

   This abnormal electrical activity causes the atria to contract erratically, resulting in an irregular heartbeat. [89] Treatment primarily focuses on restoring normal heart rhythm and controlling the heart rate to minimise the risk of complications, including stroke .
