本文报道应用经食管心房调搏方法测定了268名正常青壮年、老年人窦房结恢复时间(sNRT)及窦房传导时间(SACT)。均经体检、胸部X线、心电图及有关实验室检查等确定无心血管疾病。青年人SNRT与SACT分别为1132±157ms、120.2±41.1ms;老年人SART与SACT分别为1280.8±159.6ms、134.5±30.2ms,为确定窦房结功能提供了参数。
This article reports the use of transesophageal atrial pacing method was measured 268 normal young adults, the elderly sinoatrial node recovery time (sNRT) and sinoatrial conduction time (SACT). Are subject to physical examination, chest X-ray, ECG and related laboratory tests to determine no cardiovascular disease. The SNRT and SACT in young people were 1132 ± 157 ms and 120.2 ± 41.1 ms, respectively. The SART and SACT in the elderly were 1280.8 ± 159.6 ms and 134.5 ± 30.2 ms respectively, which provided the parameters for determining the function of the sinus node.
