Atrial arrhythmias are common problems in hypertensive patients. Atrial electromechanical delay (AEMD) can be used to evaluate development of atrial arrhythmias. The authors aimed to assess inter- and intra-AEMD in hypertensive patients. The study population consisted of 200 medically treated hypertensive patients and 151 normotensive controls. Inter-AEMD and intra-left AEMD were measured from parameters of Doppler tissue imaging. There were 72 (36%) hypertensive patients with diastolic dysfunction, 128 (64%) patients without diastolic dysfunction, and 151 healthy controls. Inter-AEMD (59 ms [36-104 ms] vs 42 ms [36-68 ms] vs 46 ms [30-82 ms]) was significantly higher in hypertensive patients with diastolic dysfunction compared with patients without diastolic dysfunction and controls. Our data demonstrated that inter-AEMD is longer in hypertensive patients with diastolic dysfunction. It may be suggested that diastolic dysfunction is associated with atrial electromechanical abnormalities, which can be associated with atrial fibrillation in hypertension.
心房心律失常是高血压患者的常见问题。心房机电延迟（AEMD）可用于评估心房心律失常的发展。作者旨在评估高血压患者的室内和室内 AEMD。研究人群包括 200 名接受药物治疗的高血压患者和 151 名血压正常的对照组。室内和室内左 AEMD 是从多普勒组织成像的参数测量的。72 名（36%）高血压患者存在舒张功能障碍，128 名（64%）患者无舒张功能障碍，151 名健康对照组。与无舒张功能障碍的患者和对照组相比，舒张功能障碍的高血压患者的室内 AEMD（59 毫秒[36-104 毫秒]）明显更高[42 毫秒[36-68 毫秒]和 46 毫秒[30-82 毫秒]）。我们的数据表明，舒张功能障碍的高血压患者的室内 AEMD 更长。这可能表明舒张功能障碍与心房机电异常有关，而心房电机械异常可能与高血压中的心房颤动有关。
