例1 患者男性,14岁,1985年5月10日入院。自诉心悸、胸闷半年。近1月感气短,不能平卧,伴尿少、浮肿、恶心不适。4月22日心电图诊断为房性心动过速,心室率140-200次/分左右,并有肝大、下肢浮肿等。经强心、利尿、抗感染、能量合剂及激素等治疗,症状好转,但房速持续不止,伴Ⅱ°一型房室传导阻滞,转入我院。病前曾反复感冒1个多月。入院体检:P120次/分,BP 90/60,活动自如,心律不齐,心率120次/分左右,来闻杂音。心脏X线片、二维超声心动图、心音图、收缩时间间期均正常。血沉、抗“O”、电解质及T_3、T_4检查亦正常。心电图示房性心动过速伴不同程度房室传导阻滞(房率150—187次/分,室率48—167次/分,房室率均自行变动,可日差很多),
Example 1 Patient Male, 14 years old, admitted to hospital on May 10, 1985. Prosecute heart palpitations, chest tightness six months. Nearly 1 month feeling short, not supine, with less urine, edema, nausea and discomfort. April 22 ECG diagnosis of atrial tachycardia, ventricular rate 140-200 times / min or so, and liver, lower extremity edema. After cardiac, diuretic, anti-infective, energy mixture and hormone therapy, the symptoms improved, but the sustained rate of more than room with type Ⅱ a-type atrioventricular block, transferred to our hospital. I had a cold for more than 1 month before my illness. Admission examination: P120 beats / min, BP 90/60, activities freely, arrhythmia, heart rate 120 beats / min, to smell the noise. Cardiac X-ray, two-dimensional echocardiography, phonocardiogram, systolic time interval were normal. ESR, anti-“O”, electrolyte and T_3, T_4 examination is also normal. ECG showed atrial tachycardia with varying degrees of atrioventricular block (room rate 150-187 beats / min, room rate 48-167 beats / min, atrioventricular rate changes on their own may be a lot of bad day)
