Final answer:
Potassium channel blockers, such as amiodarone and procainamide, are class IV antidysrhythmic meds used to treat abnormal electrical activity in the heart, called cardiac dysrhythmia.
Step-by-step explanation:
Potassium channel blockers, such as amiodarone and procainamide, are class IV antidysrhythmic meds used to treat abnormal electrical activity in the heart, called cardiac dysrhythmia.
These medications impede the movement of Potassium (K+) ions through voltage-gated Potassium (K+) channels in the heart. By blocking these channels, they help regulate the electrical signals in the heart and restore a normal heart rhythm.
Examples of Class IV antidysrhythmic meds include amiodarone, procainamide, and verapamil.
