[Treatment of syncope]

Area of Science:

• Cardiology
• Internal Medicine

Context:

• Syncope management requires understanding diverse pathophysiological mechanisms.
• Current therapeutic strategies vary significantly based on syncope type.

Purpose:

• To outline current, evidence-based therapeutic approaches for different syncope etiologies.
• To emphasize the importance of mechanism-specific treatment and diagnostic correlation.

Summary:

• Reflex syncope management focuses on patient education and trigger avoidance; drug therapies are largely ineffective. Orthostatic hypotension treatment involves addressing drug-induced autonomic failure, increasing salt/fluid intake, and using compression. Cardiac pacing is indicated for frequent syncope with ECG correlation.
• Pacemaker and defibrillator therapy are crucial for bradycardia and tachycardia arrhythmias, respectively, though establishing causal links can be challenging. Miniaturized ECG recorders aid diagnosis, but suspicion of life-threatening arrhythmias necessitates careful evaluation.

Impact:

• Optimized syncope treatment strategies can improve patient outcomes and reduce healthcare burden.
• Accurate diagnosis and targeted therapy are essential to differentiate syncope from sudden cardiac death.
• Advances in diagnostic tools like implantable ECG recorders enhance the management of recurrent syncope.
