Rezumat

Background: Tilt table testing (TTT) induces passive orthostatic stress that influences hemodynamics and determines cardiovascular system to react. When this process fails, the vasovagal syncope occurs. It could develop in three main patterns: classic, dysautonomic (hemodynamic parameters are falling from the beginning of TTT) and orthostatic intolerance (like dysautonomic but without abrupt drop in syncope). Aim: to examine the hemodynamic parameters modification during TTT in patients with syncopal migraine. Methods: Were studied 135 patients divided as: gr I (65 pts) – syncopal migraine, gr II (38 pts) - migraine and gr III (32 pts) - syncope. All patients underwent TTT (Westminster protocol). Hemodynamic parameters (heart rate, systolic and diastolic blood pressure) were recorded every minute. Values were analyzed from baseline (0*), at third (3*), sixth (6*) and ninth (9*) minutes, three minutes before syncope (-3), syncope (S) and three minutes after recovery (+3) as mean and variation from baseline. All data collected were analyzed using SPSS software. Results: The heart rate and diastolic blood pressure mean values and variations from baseline presented a classical pattern with more pronounced modifications for syncopal migraine patients (fig. 1, 3). Systolic blood pressure in all groups demonstrated dysautonomic pattern (fig 2).Conclusion: In syncopal migraine patients hemodynamic parameters react differently compared to migraine group and syncope group, presenting a classic pattern for heart rate and diastolic blood pressure modifications and a dysautonomic pattern for systolic blood pressure, suggesting an abnormal cardiovascular autonomic function during TTT in these patients.
