Cardiac Channelopathies

Cardiac channelopathies are genetic conditions that affect the ion channels in heart cells, which are responsible for controlling heartbeats. These channels help regulate the flow of ions, like sodium and potassium, that create electrical signals for the heart to beat properly. When these channels malfunction, it can lead to abnormal heart rhythms, or arrhythmias, which may increase the risk of fainting, seizures, or even sudden cardiac arrest. Understanding these conditions is important for diagnosis and treatment, as they can significantly impact heart health.
