体表窦房结电图评定窦房结功能的临床应用(附55例病例分析)

CLINICAL SIGNIFICANCE OF SNEb IN THE MEASUREMENT OF SINUS NODE FUNCTION (A REPORT 55 CASES)

采用体表窦房结电图检测系统,通过C导联及程控双时值放大器等,分别对90例正常人、9例窦缓及46例病窦患者检测,对后二者还通过食道心房调搏测定窦房结恢复时间和窦房传导时间、ECG、24h动态心电监测及阿托品试验,并加以比较。认为体表窦房结电图较稳定可靠,便于重复,值得临床推广。

Sinus node electrogram of body surface (SNEb) was recorded in 90 normal subjects, 9 persons with bradyeardia and 46 patients with sick sinus syndrome (SSS). Patients with bradycardia and SSS were put to the test of standard 12 leads ECG, ambulatory ECG monitoring atropine test and transesophageal atrial pacing besides SNEb. Comparison was made between SNEb and other methods. It was concluded that SNEb is a stable and reliable method. It is easy to be spreaded in clinics.
