Antiarrhythmics or antiarrhythmics are drugs that are used primarily in the treatment of cardiac arrhythmias (arrhythmia), although in most rhythm disorders, no treatment is required. Medications can be used in arrhythmia attacks or are taken to prevent and control arrhythmia.
There are different types of antiarrhythmics: the choice for a particular type depends on the type of arrhythmia, the patient's response to the drug and the presence or absence of other conditions. Types of antiarrhythmics
Depending on the way they work, antiarrhythmics are classified into different classes. For example, class 1 antiarrhythmias, also called membrane stabilizers, belong to lidocaine. Class 2 antiarrhythmics are beta blockers such as atenolol. These work by blocking certain cell proteins (receptors). Class 3 antiarrhythmics are agents that block the potassium channels on the cell membrane, such as amiodarone. Class 4 antiarrhythmias, including verapamil, block other channels on the cell membrane, namely the calcium channels. Operation
Antiarrhythmics change the conduction of electrical signals in the heart. The type of change depends on the type of antiarrhythmic. Some agents, such as beta blockers, block the transmission of signals to the heart. Others, such as adenosine, work on the conduction of signals within the heart and again others, such as calcium antagonists, affect the heart muscle response to the signals.
