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.
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
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.
An arrhythmia is an irregular heartbeat that occurs due to a problem with the electrical activity of your heart. Types of arrhythmia include: Tachycardia. A faster-than-normal heart rate. Bradycardia.
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.
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.
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 .
A fast heart rate could be caused by stress, a fever, caffeine, or a condition like hyperthyroidism and low blood pressure. Here's when you need to a see a doc. Coffee Isn't The Only Drink That ...
