心得安试验诊断功能性 ST—T 改变己为人们熟悉。在临床实践中发现它还可诊断功能性高 P 波、U 波及正确诊断左室高电压伴 ST—T 改变,报告如下。一、诊断功能性高 P 波例1.男,33岁。呼吸不畅就诊,查体无异常,ECG 示窦律,低电压趋势,高 P 波(PⅡ>1/2R)和 ST 改变(STv_5压低0.1mv),拟诊植物神经功能紊乱,给予心得安试验,心率减慢,高 P 波和 ST 改变恢复正常。例2.男,18岁。招生体检发现心动过述,ECG 示窦速,高 P 波,ST 改变(STⅡ、Ⅲ、avF 呈斜上型压低,拟诊精神紧张
Experience Trials Diagnosis Functional ST-T changes are already familiar. Found in clinical practice it can also diagnose functional high P wave, U wave and correct diagnosis of left ventricular high voltage with ST-T changes, the report is as follows. First, the diagnostic function of high P wave 1. Male, 33 years old. Respiratory failure, physical examination without abnormalities, ECG showed sinus rhythm, low voltage trends, high P wave (P Ⅱ> 1 / 2R) and ST changes (STv_5 depression 0.1mv), to diagnose autonomic dysfunction, , Heart rate slowed, high P wave and ST changes returned to normal. Example 2. Male, 18 years old. Enrollment Physical examination found echocardiography, ECG showed sinus speed, high P wave, ST changes (ST Ⅱ, Ⅲ, avF was oblique type depression, to be diagnosed with mental stress
