arrhythmogén

Arrhythmogen is a term used in medicine and cardiology to describe any factor that can cause or contribute to the development of an arrhythmia. An arrhythmia is a condition characterized by an abnormal heart rhythm, meaning the heart beats too fast, too slow, or irregularly. Arrhythmogens can be intrinsic to the heart itself, such as genetic mutations affecting ion channels or structural abnormalities, or they can be extrinsic, originating from outside the heart.

Extrinsic arrhythmogens include a wide range of substances and conditions. Certain medications, particularly those used to treat heart conditions or other diseases, can have proarrhythmic effects as a side effect. Electrolyte imbalances, such as low potassium or magnesium levels, are also significant arrhythmogens, as these ions play crucial roles in electrical conduction within the heart. Toxins, including recreational drugs like cocaine and alcohol, can trigger dangerous arrhythmias. Furthermore, systemic conditions like severe infections, thyroid dysfunction, and even stress can act as arrhythmogens. Understanding arrhythmogens is vital for diagnosing and managing cardiac arrhythmias effectively, as identifying and addressing these triggers is often a key part of treatment.
