Study Notes
Syncope Evaluation
- Syncope is a temporary loss of consciousness due to insufficient blood flow to the brain.
- It's characterized by sudden onset, short duration, and spontaneous recovery.
- Syncope has various causes and requires careful evaluation.
- The provided document details a decision tree for evaluating syncope.
Key Features of the Decision Tree
- Red Flags: Chest pain, palpitations, exertional syncope, family history of sudden cardiac death, abnormal ECG, history of heart disease, indicate a higher risk of a serious cardiac cause.
- Syncope vs. Seizure Differentiation: Distinguishing syncope from seizures is crucial. Syncope involves rapid recovery and prodromal symptoms (e.g., sweating, nausea), while seizures feature postictal confusion, tongue biting, and prolonged confusion.
- High-Risk Diagnoses to Rule Out: The decision tree highlights the need to rule-out serious conditions like abdominal aortic aneurysm (AAA), ectopic pregnancy, subarachnoid hemorrhage, and pulmonary embolism (PE).
Neurally Mediated Syncope
- Vasovagal Syncope: Commonly known as a "faint," characterized by the "3 Ps": posture (standing), prodrome (sweating, nausea, warmth), precipitating trigger (emotional stress, hot environments).
- Situational Syncope: Triggered by specific activities involving bodily function changes, such as defecation, swallowing, urination, or coughing.
- Carotid Sinus Syncope: Occurs with neck stimulation (e.g., turning the head or wearing tight collars).
Disposition Recommendations
- High-risk cases require urgent care or hospitalization.
- Low-risk cases warrant reassurance and outpatient follow-up.
Additional Information
- Pulmonary Embolism (PE) Evaluation: The PERC (Pulmonary Embolism Rule-Out Criteria) score, along with the Wells score, helps assess the probability of PE before ordering a D-dimer test. If PERC is negative, additional testing might be unnecessary.
- Evaluation Framework: Factors like orthostatic intolerance (caused by medications, underlying medical conditions like diabetes, polyneuropathy, and Parkinson's disease) are considered.
