| الوصف: | Postural Orthostatic Tachycardia Syndrome (POTS) might have altered endothelial function, causing abnormal vasomotion in the body and in cerebral vessels. Non-cardiac symptoms experienced by these patients suggest that they may be especially sensitive to acute reduction of arterial CO 2 concentration during hyperventilation (HV). We hypothesized HV induces more significant blood pressure (BP) fall with compensatory higher HR increase in POTS. Subjects previously diagnosed with POTS and gender-matched controls were enrolled. ECG, finger BP, and EtCO 2 were continuously recorded during hyperventilation (1breaths/sec) over 30 seconds. Hemodynamic parameters were computed in absolute and change. We studied 14 POTS and 15 controls matched for age (29 ± 2 vs 30 ± 3; p=0.63) and BMI (24.1±0.8 vs 23.0±0.7; p=0.34). At baseline mean HR (79±4 vs 70±3 bpm, p=0.12) was comparable and SBP was higher (113±3 vs 105±2 mmHg, p2 values were comparable at baseline (35±1 vs 38±1 mmHg, p=0.14) and at the end of the maneuver (20±1 vs 21±1 mmHg, p=0.58). POTS had greater SBP drop (-27±2 vs -19±2 mmHg, p |
