In heart failure (HF), anaerobic threshold (AT) may be indeterminable but its value held a relevant prognostic role. AT is evaluated joining three methods: V‐slope, ventilatory equivalent, and end‐tidal methods. The possible non‐concordance between the V‐slope (met AT) and the other two methods (vent AT) has been highlighted in healthy individuals and named double threshold (DT).
