Objective To observe the morphological structures of sinoatrial node (SAN) in pig hearts.

目的观测猪心窦房结形态学结构特点。

The sinoatrial node is located at the junction of the superior vena cava and the right atrium.

窦房结位于上腔静脉与右心房的交界处。

Conclusion Hyperthyroidism presenting as bradycardia is related to the sinoatrial node function.

结论甲亢可影响窦房结功能使其心动过缓。

When the sinoatrial node starts to malfunction it can cause dangerously slow or erratic rhythms to develop.

窦房结出了问题，心律会变缓或变紊乱，这很危险。

An artificial pacemaker works by restoring the function of a faulty sinoatrial node, the heart's natural pacemaker.

人工心率调整器的作用是使紊乱的心脏天然心率调整器窦房结恢复正常功能。

Objective To study the effect of Qiangxin Fumai Granule (QXFMG) on rabbits induced with acute injury of sinoatrial node.

目的观察强心复脉颗粒对家兔窦房结急性损伤模型的影响。

It is characterized by sinoatrial node dysfunction and often includes atrioventricular node disease and bundle branch block.

它的特征是窦房结功能障碍并常伴有房室结疾病和束支传导阻滞。

Cardiomyocytes in the sinoatrial node This image shows a section of the sinoatrial node, a pacemaking area of the right atrium of the heart.

窦房结的心肌细胞：这张图显示了窦房结的切面，右心房的一块起搏区。

Rabbit brady arrhythmia model due to acute sinoatrial node damage was made by overlaying 30% formaldehyde on the surface of sinoatrial node area.

用30%甲醛外敷窦房结区表面，造家兔窦房结急性损伤致缓慢型心律失常模型。

Normally the sinoatrial node generates regular electrical pulses that spread across the Chambers of the heart, causing the cells to contract in synchrony.

正常情况下，窦房结产生规律的电脉冲，传入各心房，再带动细胞同步收缩。

Objective: To study the effect of Bingdoukang Oral Solution (hereinafter referred to as BDK) on rabbits induced with acute injury of sinoatrial node.

目的：研究病窦康口服液对家兔窦房结急性损伤的影响。

Objective:To investigate the architecture of collagen fibers of human sinoatrial node and its relationship to the central artery penetrated to the node.

目的：观察人窦房结胶原纤维网架的构筑及其与窦房结中央动脉的关系。

Conclusion the results suggest that dle effect of parasympathetic nerve activity on atrioventricular node function is larger than that of sinoatrial node.

结论提示迷走神经对房室结功能影响大于对窦房结功能影响。

Objective:To discuss incidence, clinical significance and result of bradycardic dysfunction of sinoatrial node in inferior wall acute myocardial infarction(AMI).

目的：讨论急性下壁心肌梗死患者缓慢性窦房结功能紊乱的发生率、临床意义及转归。

The size of the vulnerable window was largest for pulmonary vein foci, becoming markedly smaller for right atrial foci, especially those near the sinoatrial node.

肺静脉异位灶的易损窗口最宽，右房异位灶的易损窗口明显变窄，在窦房结附近的异位灶，易损窗口尤其窄。

Sick sinus syndrome (SSS) is a cardiac conduction disorder characterized by symptomatic dysfunction of the sinoatrial (SA) node.

病窦综合征（SSS）是以窦房结症状性功能失调为特征的心脏传导障碍。

This study reports the results of sinus node electrogram (SNE) by electrode catheterization and directly measured sinoatrial conduction lime (SACT_D) in 48 patients.

本文报告对48例患者，右心导管法描记窦房结电图(SNE)及直按测定窦房传导时间(SACT_D)的结果。
