What is antiarrhythmic?

Antiarrhythmics is a class of drugs that suppress abnormal heart rhythms called cardiac arrhythmias. These drugs help to treat arrhythmias such as ventricular fibrillation, ventricular tachycardia and atrial fibrillation. There are several types of antiarrhythmic substances, including beta blockers and ionic channel blockers. Each of them works in a slightly different way. They can cause symptoms such as irregular or rapid heart rhythm, heart palpitations, dizziness, fainting, shortness of breath and chest pain. Antiarhythmic drugs operate by slowing the electrical impulses that are generated in the heart. This allows the heart rhythm to normalize.

arrhythmias are diagnosed with a test called electrocardiogram. In this test, the electrodes are placed over the chest and used to detect electrical pulses generated by the heart. Diagnosis of various types of arrhythmias made based on interpretation of electrical activity pattern. After diagnosis, the patient will work with his doctor to determine the most suitable antiarrhythmické therapy. The patient can often try two or three different medicines before they deal with the most effective option. While the patient tries different medicines, it can wear a holter monitor, a portable device that records electrical pulses from the heart to evaluate the effects of the drug.

There are four classes of antiarrhythmic substances. Time classes I are sodium channel blockers and reduce sodium ions through cellular sodium channels. Class III agents are potassium channel blockers and Class IV agents are calcium channel blockers. All three of these drug classes work by changing electrical pulses generated by the heart. Each medicine affects the ion, so they have different effects on the heart and can treat different types of arrhythmias.

Class II agents are beta blockers and work differently from ionic channel blockers. Beta blocking drugs block the effects of hormones called catecholamines. These hormones playHe eats a role in a stress reaction and can contribute to heart arrhythmias. Beta blockers reduce the ability of catecholamines to affect heart rate and increase blood pressure and can therefore treat hypertension and arrhythmias.

Antiarrrhythmic drugs can cause a number of side effects. Possible effects include an allergic reaction, cough, loss of appetite, constipation or diarrhea, blurred vision, shortness of breath, dizziness, fainting, chest pain, abnormally fast or slow heart rhythm and swelling of legs or legs. Anyone who experiences one of these symptoms should inform your doctor as soon as possible.
