What is the initial treatment for an unstable patient with atrial flutter?

• A. Cardioversion
• B. Anticoagulation
• C. Beta-blocker administration
• D. Calcium channel blocker administration

Answer: (A)

The initial treatment for an unstable patient with atrial flutter is cardioversion. In cases of atrial flutter, especially when the patient is unstable, immediate intervention is necessary to restore normal rhythm and stabilize the patient. Cardioversion is a procedure where electrical shocks are delivered to the heart to reset its rhythm.

When a patient is unstable, this typically means they are experiencing significant symptoms such as hypotension, altered mental status, or chest pain due to inadequate circulation. In such situations, rapid cardioversion is crucial as it can quickly restore effective atrial and ventricular contractions, thereby improving blood flow and stabilizing the patient's condition.

Other treatments, like anticoagulation, beta-blockers, or calcium channel blockers, may be appropriate for more stable patients, but they are not the first-line immediate options for someone who is unstable, as they do not provide the rapid correction needed in an urgent scenario.
