Final answer:
Certain antiarrhythmics, like sodium channel blockers, can unmask Brugada pattern on an ECG. Another way to unmask this pattern is by performing a sodium channel blocker challenge.
Step-by-step explanation:
Brugada pattern is a specific pattern that can be seen on an electrocardiogram (ECG) which indicates a potential risk for life-threatening arrhythmias. Certain antiarrhythmics can unmask this pattern by further altering the electrical activity of the heart. Examples of antiarrhythmics that can unmask Brugada pattern include sodium channel blockers such as flecainide and ajmaline.
To unmask Brugada pattern using EKGs, a sodium channel blocker challenge can be performed. This involves administering a medication that blocks sodium channels, such as procainamide or flecainide, to induce the characteristic EKG pattern associated with Brugada syndrome.
It is important to note that the administration of these medications should only be done under the guidance and supervision of a healthcare professional.
