Initial Impression: Possible Cardiac Syncope/Arrhythmia Justification for F2 Classification: - Unresponsive patient with witnessed collapse and shallow breathing - Possible cardiac etiology, requiring rapid assessment and potential intervention - Time-sensitive condition with potential for deterioration Differential Diagnoses: 1. Cardiac Arrhythmia (high probability given history of palpitations) 2. Vasovagal Syncope (less likely due to unresponsiveness) 3. Seizure (less likely, no reported tonic-clonic activity) 4. Hypoglycemia (less likely, no history of diabetes) 5. Stroke (possible, needs further assessment) Required Actions: - Dispatch of ground EMS with ALS capabilities - Rapid assessment of airway, breathing, and circulation - Continuous monitoring of vital signs - Preparation for potential defibrillation or other advanced interventions - Transport to nearest hospital with cardiac capabilities
