Figure 2 End-tidal CO 2 at the...

End-tidal CO₂ at the ventilatory threshold vs. $\dot{V} E / \dot{V} C O_{2}$ metrics. PETCO₂ correlation between PETCO₂ at ventilatory threshold and (A) $\dot{V} E / \dot{V} C O_{2}$ -total slope (B) $\dot{V} E / \dot{V} C O_{2}$ -early slope (through $V T$ ⁠), (C) $\dot{V} E / \dot{V} C O_{2}$ -nadir in individuals with hypertrophic cardiomyopathy vs. athletes. R value for Pearson correlation and corresponding P-value are shown.
