What is the treatment approach for tachycardia?

• A. Slow the heart rate
• B. Speed up the heart rate
• C. Block conduction
• D. Increase blood pressure with fluids

Answer: (A)

Tachycardia is an abnormally fast heart rate, so the main aim is to reduce the rate to relieve symptoms and improve heart function. Slowing the rate allows longer filling time during diastole, improves coronary blood flow, lowers myocardial oxygen demand, and often helps restore a more normal rhythm pattern with fewer hemodynamic compromises. In practice, this can be achieved with vagal maneuvers or drugs that slow AV nodal conduction (such as certain beta-blockers or calcium channel blockers) and, depending on the rhythm and stability, other rhythm-specific therapies or even synchronized cardioversion if needed. The other options don’t address the underlying issue in the general approach: speeding up the heart rate would make tachycardia worse, blocking conduction is not the universal first-line strategy for tachycardia, and simply increasing fluids to raise blood pressure doesn’t treat the rhythm itself.
