"Fast AF" is slang for extremely fast. "AF" is an abbreviation for "as f***," used as an intensifier.
In the context of the provided reference, "fast AF" could refer to Atrial Fibrillation (AFib), a heart condition characterized by an irregularly and often abnormally fast heart rate. A normal resting heart rate is typically between 60 and 100 beats per minute. During AFib, the heart can beat much faster, often exceeding 100 beats per minute and potentially reaching even higher rates.
Here's a breakdown:
- Atrial Fibrillation (AFib): An irregular heart rhythm (arrhythmia) where the upper chambers of the heart (atria) beat chaotically and irregularly.
- Heart Rate: The number of times your heart beats per minute.
- Normal Heart Rate: Usually between 60 and 100 beats per minute at rest.
- Fast Heart Rate in AFib: Can be significantly higher than normal, leading to symptoms like palpitations, shortness of breath, and fatigue. The rate can go well above 100 bpm, which someone might describe colloquially as "fast AF."
While "fast AF" is not a medical term, understanding its meaning in the context of AFib can highlight the severity and impact of the condition. If you suspect you have AFib, it's crucial to seek medical attention for diagnosis and treatment.
