antytachykardiczne

Antytachykardiczne, also known as antiarrhythmics, is a classification of medications used to treat and prevent abnormally fast heart rhythms, a condition called tachycardia. Tachycardia occurs when the heart beats faster than normal, either at rest or during activity. This can be caused by various factors, including underlying heart conditions, electrolyte imbalances, stress, or certain medications.

These drugs work by influencing the electrical activity of the heart. They can achieve this by altering the speed of electrical impulse conduction, affecting the duration of the heart's electrical cycle, or suppressing abnormal electrical pathways. Different classes of antiarrhythmics target specific mechanisms within the heart's electrical system, leading to a diverse range of effects and applications.

The choice of antiarrhythmic medication depends on the specific type of tachycardia, its severity, and the patient's overall health. Some common types include beta-blockers, calcium channel blockers, and sodium channel blockers, each with distinct mechanisms of action. Antiarrhythmics are vital in managing conditions such as atrial fibrillation, supraventricular tachycardia, and ventricular tachycardia, aiming to restore a normal heart rhythm, improve symptoms, and reduce the risk of complications like stroke or sudden cardiac arrest. They are typically prescribed and monitored by healthcare professionals due to potential side effects and the need for careful dosage adjustment.
