Insights
This guideline updates syncope (fainting) diagnosis and management for adults and children. It emphasizes patient history and ECGs, revises provocative testing, and highlights risk stratification for better patient outcomes.
Area of Science:
- Cardiology
- Clinical Practice Guidelines
Background:
- Syncope (fainting) management requires updated evidence-based strategies.
- Previous guidelines focused on primary examination for syncope diagnosis.
Purpose of the Study:
- To summarize and analyze the evidence base for syncope evaluation and management.
- To present the 2017 American College of Cardiology/American Heart Association Task Force guideline for syncope.
Main Methods:
- Review of published evidence and clinical experience.
- Analysis of diagnostic criteria, including anamnestic and ECG findings.
- Evaluation of provocative tests and risk stratification methods.
Main Results:
- Strengthened emphasis on patient history (anamnestic criteria) for syncope diagnosis.
- Supplementation of ECG criteria for identifying arrhythmic syncope.
- Revised indications and lowered class of recommendations for provocative tests.
- Key value placed on risk stratification for short- and long-term adverse outcomes.
- Summarized treatment advances for various syncope causes (e.g., sarcoidosis, arrhythmias, orthostatic hypotension).
Conclusions:
- The guideline provides an updated framework for diagnosing and managing syncope in adult and pediatric patients.
- It emphasizes a comprehensive approach integrating patient history, ECG, and risk stratification.
- The guideline offers valuable insights for clinicians in developing optimal syncope management strategies.
Abstract:
The article presents key points of published in March 2017, Guideline for the Evaluation and Management of Patients With Syncope (A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines, and the Heart Rhythm Society). This document contains summary and analysis of evidence base and accumulated experience in this field and reflect further development of the problem of the management of adult and pediatric patients with suspected syncope. Traditionally, the basis of diagnostic algorithm of these patients has been primary examination, and in the present guideline one can find strengthening of the importance of anamnestic criteria, and supplementation of ECG criteria of arrhythmic syncope. At the same time, the diagnostic value of provocative tests has been revised, and the class of indications for these tests has been lowered. According to the guideline, along with diagnosis of the cause of fainting, risk stratifcation of short- and long-term adverse outcomes has a key value. The guideline summarizes latest achievements in the treatment of fainting in sarcoidosis, arrhythmogenic right ventricular dysplasia, primary arrhythmic heart diseases, orthostatic hypotension, and reflex-mediated syncope. Despite orientation on specifc properties of medical care in the USA, the guideline can be useful to practical physicians in choice of the best strategy of diagnosis and treatment of syncope in each individual case.

01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

Timely documentation is crucial to ensure continuity of care for patients. Any delays in recording or reporting medical information can result in medical errors and even adverse patient outcomes. From medication administration to diagnostic test results, every detail must be accurately and promptly documented to provide the best possible care for patients.
