What is a suitable intervention if a patient with second-degree AV block type 1 shows hemodynamic instability?

• A. Immediate defibrillation
• B. Pacemaker preparation
• C. Medicate with anticoagulants
• D. Increase physical activity

Answer: (B)

In cases of second-degree AV block type 1, also known as Wenckebach, the heart's electrical signals are progressively delayed until a beat is dropped. If a patient experiences hemodynamic instability, it indicates that their blood pressure and heart rate may not be adequate to perfuse vital organs. In such circumstances, preparing for pacing is an appropriate intervention because it can help restore a more consistent heart rhythm and improve cardiac output. Pacemaker therapy can quickly address the conduction block by providing electrical impulses to stimulate the heart if the block is causing significant symptoms or hemodynamic compromise. This intervention can stabilize the patient and prevent further complications that could arise from inadequate cardiac function. Other options, such as immediate defibrillation, are not relevant here as it is used for life-threatening arrhythmias like ventricular fibrillation, not for second-degree AV blocks. Medications like anticoagulants are typically used for thromboembolic prevention and do not address the immediate need for stabilization in a case of heart block. Increasing physical activity would also be counterproductive, as it could exacerbate the patient's instability.
