To observe the heart rate turbulence (HRT) in patients with masked hypertension (MH), and white-coat hypertension (WCH).
Patients were classified on the basis of clinic and 24h ambulatory blood-pressure monitoring: essential hypertension (H, n = 32), masked hypertension (MH, n=26), white-coat hypertension (WCH, n = 29) and normotension (NT, n = 30). For each subject, we recorded 24 hours holter monitoring electrocardiogram, calculated the turbulence onset (TO) and turbulence slope (TS) and compared the differences.
Compared with NT controls, the differences of TO and TS in the patients with EH, MH and WCH were statistically significant (p < 0.01). No significant differences were found between the EH, MH and WCH groups.
The HRT in EH, MH and WCH patients is significantly lower, when their autonomic nerve function is damaged.
观察隐匿性高血压（MH）和白大衣高血压（WCH）患者的心率震荡（HRT）情况。
根据临床及24小时动态血压监测对患者进行分类：原发性高血压（H，n = 32）、隐匿性高血压（MH，n = 26）、白大衣高血压（WCH，n = 29）和血压正常者（NT，n = 30）。对每位受试者记录24小时动态心电图监测，计算震荡起始（TO）和震荡斜率（TS）并比较差异。
与NT对照组相比，EH、MH和WCH患者的TO和TS差异有统计学意义（p < 0.01）。EH、MH和WCH组之间未发现显著差异。
EH、MH和WCH患者在自主神经功能受损时，其HRT显著降低。
