What does 'A' in B.E.F.A.S.T. represent?

The 'A' in B.E.F.A.S.T. stands for "Arm weakness." This acronym is used as a quick way to remember the signs of a stroke, with each letter representing a key symptom or action to take. Specifically, "A" indicates that one of the potential warning signs of a stroke is weakness or numbness in one arm. Recognizing this symptom is crucial because it can help prompt individuals to seek immediate medical attention, which is vital for improved outcomes in stroke treatment.

Awareness of symptoms, while important, is not the specific focus of 'A.' Arrhythmia checks and assessment of pulse are related to heart health and may be relevant in different medical contexts, but they do not pertain to the B.E.F.A.S.T. acronym, which is solely focused on recognizing strokes.
