目的 观察老年患者直立倾斜试验(TTT)的严重反应,并总结其预防和处理的体会。 方法 TTT的倾斜角度为70°,基础试验最长时间为45 min,多阶段异丙肾上腺素激发试验最长时间为30 min。整个过程中持续心电和血压监测,维持良好的静脉通路。 结果 21例TTT阳性,其中10例出现严重反应,分别为窦性心动过缓和窦房传导阻滞3例、完全性房室传导阻滞引起心房停搏3例,严重低血压4例。所有患者在发生晕厥后立刻放至平卧位,抬高下肢;心率慢者给予阿托品静推。有2例行胸外心脏按压,4例吸氧。所有患者经处理神志很快转清,有2例经10 min抢救后血压才恢复正常,但未发生并发症。 结论 TTT虽然为一项无创性检查,但严重反应并不罕见。尤其对老年人应严格掌握适应证,及时控制异丙肾上腺素滴速,密切观察心率和血压,有助于防止发生意外。
目的 觀察老年患者直立傾斜試驗(TTT)的嚴重反應,併總結其預防和處理的體會。 方法 TTT的傾斜角度為70°,基礎試驗最長時間為45 min,多階段異丙腎上腺素激髮試驗最長時間為30 min。整箇過程中持續心電和血壓鑑測,維持良好的靜脈通路。 結果 21例TTT暘性,其中10例齣現嚴重反應,分彆為竇性心動過緩和竇房傳導阻滯3例、完全性房室傳導阻滯引起心房停搏3例,嚴重低血壓4例。所有患者在髮生暈厥後立刻放至平臥位,抬高下肢;心率慢者給予阿託品靜推。有2例行胸外心髒按壓,4例吸氧。所有患者經處理神誌很快轉清,有2例經10 min搶救後血壓纔恢複正常,但未髮生併髮癥。 結論 TTT雖然為一項無創性檢查,但嚴重反應併不罕見。尤其對老年人應嚴格掌握適應證,及時控製異丙腎上腺素滴速,密切觀察心率和血壓,有助于防止髮生意外。

Objective To summarize the onset and the management of serious responsiveness during the tilt-table test (TTT), and the prevention measures. Methods Thirty-six elderly patients (26 males and 10 females, aged between 60-70) were tested with a tilt angle of 70 degrees for a maximum of 45 minutes and then processed with isoproterenol-provocative tilt testing. ECG and blood pressure were monitored during the test and the peripheral intravenous cannula were maintained for all patients with normal saline. Results Twenty-one of the 36 patients were defined as positive including 10 showing serious responsiveness. Of the 10 patients, 3 had a history of atherosclerosis involving internal carotid arteries; among the 3 with bradycardia, 2 were associated with II° A-V block, and another one was with chronic atrial fibrillation. The serious reponsiveness included asystole for more than 5 seconds(3 cases) , serious bradycardia for more than 1 minute(3 cases) , and serious hypotension for more than 1 minute (4 case), respectively. Those with serious responsiveness were managed with returning to supine position, or intraveneous atropine, or CPR (2 cases), or oxygen given(4 cases). Only 2 hypotensive patients recovered gradually in 10-minute emergent management while others recovered rapidly and with no complication. Conclusions TTT may result in serious responsiveness especially in elderly patients though it is non-invasive method. Therefore, proper patient selection according to the indications, control of isoproterenal infusion and close observation of vital signs are important for a safe consequence.
