Sinus Tachycardia: a Multidisciplinary Expert Focused Review.

Area of Science:

• Cardiology
• Autonomic Medicine
• Neurology
• Allergy and Immunology
• Endocrinology
• Pulmonology
• Psychology
• Exercise Physiology

Background:

• Sinus tachycardia (ST) is a frequent clinical finding, often without clear physiological triggers in healthy individuals.
• ST can be a normal variant, a symptom of treatable conditions like pulmonary embolism or infection, or indicative of complex disorders such as inappropriate sinus tachycardia or post-COVID syndrome.
• The diagnostic and therapeutic approach to ST can be challenging due to its varied etiologies and overlapping specialist involvement.

Purpose of the Study:

• To provide a comprehensive understanding of sinus tachycardia (ST) by integrating insights from multiple medical disciplines.
• To clarify the classification, potential causes, and management strategies for ST.
• To emphasize the importance of a multidisciplinary approach for improved patient care.

Main Methods:

• This article synthesizes current knowledge on sinus tachycardia (ST).
• It incorporates expert perspectives from international specialists across Neurology, Psychology, Autonomic Medicine, Allergy and Immunology, Exercise Physiology, Pulmonology and Critical Care Medicine, Endocrinology, Cardiology, and Cardiac Electrophysiology.
• The approach focuses on a holistic understanding of ST, considering its broad spectrum of presentations and underlying pathologies.

Main Results:

• Sinus tachycardia (ST) presents a diagnostic challenge due to its diverse origins, ranging from benign physiological responses to indicators of significant underlying pathology.
• Effective management requires a thorough differential diagnosis, considering conditions like pulmonary embolism, anemia, infection, hyperthyroidism, inappropriate sinus tachycardia, postural tachycardia syndrome, mast cell disorders, and post-COVID conditions.
• A collaborative, interdisciplinary approach is crucial for accurate diagnosis and optimal treatment of patients experiencing persistent or paroxysmal ST.

Conclusions:

• Sinus tachycardia (ST) necessitates a broad differential diagnosis and a comprehensive evaluation.
• Integrating expertise from various medical fields, including cardiology, neurology, and immunology, is essential for a complete understanding and effective management of ST.
• This multidisciplinary perspective aims to enhance diagnostic accuracy and improve patient outcomes for individuals with ST.
