[Differential diagnostics of unclear syncope]

Area of Science:

• Cardiology
• Neurology

Background:

• Syncope diagnosis presents a significant challenge due to the intermittent nature of its underlying causes.
• Accurate differentiation from other transient losses of consciousness (TLOC) is essential.

Purpose of the Study:

• To emphasize the critical role of detailed, standardized anamnesis in syncope evaluation.
• To highlight the importance of risk stratification for appropriate patient management.
• To outline a standardized diagnostic approach for persistent unclear syncope.

Main Methods:

• Standardized patient history taking (anamnesis).
• Risk stratification protocols.
• Extended diagnostic tools including tilt table testing, carotid sinus pressure testing, prolonged telemetric monitoring, and implantable loop recorders (ILR).

Main Results:

• Detailed anamnesis effectively differentiates syncope from other TLOC and identifies potential causes.
• Risk stratification guides the necessity of further investigations, avoiding unnecessary procedures for benign cases.
• Standardized extended diagnostics aid in clarifying the cause of syncope when initial evaluation is inconclusive.

Conclusions:

• A systematic approach combining thorough anamnesis, risk stratification, and targeted extended diagnostics is vital for effective syncope management.
• Timely diagnosis and treatment, particularly for cardiac syncope, can be significantly improved through standardized evaluation pathways.
• The use of advanced tools like ILRs is indicated for complex or persistent cases of unexplained syncope.
