Figure 3. Worsening Orthostatic Tachycardia After 75-gr Oral Glucose.

Figure 3.

Supine and upright heart rate (HR) while fasting and after 90 minutes of oral glucose in POTS (A) and healthy controls (B). HR, stroke volume (SV), total peripheral resistance (TPR), mean arterial pressure (MAP) and cardiac output (CO) percent changes calculated from baseline values in POTS patients (black) and controls (gray) (C). Absolute changes in HR from baseline (fasting) at different timepoints up to 120 minutes after glucose consumption (D). P-values were calculated using Mann-Whitney U test.
