How do Antiarrhythmic Medications Affect Histology?
The action of antiarrhythmic drugs on the microscopic structure of heart tissues is essential for their therapeutic efficacy. These medications primarily influence the function and structure of cardiac myocytes, the muscle cells responsible for heart contraction. They can alter the histological properties of these cells, impacting their size, shape, and the organization of intercalated discs, which are crucial for synchronized contraction.
