病例介绍患者女性,39岁,农民。因胸闷,心慌、全身乏力10天入院。病前1个月内无“感冒”及“腹泻”史。体检:心界不大,心律不齐,平均心率90次/分,心前区未闻及杂音。两肺(一)。实验室检查:血常规,抗“O”、血沉、SGOT、CPK、LDH及LDHS均正常。X线胸片正常。心电图示:窦性心律;吸气时短暂阵发性房速伴交替性文氏周期(图见封三)。图中可见呼气及窦性心律,吸气时呈短暂阵发性房速,P′—P′相等,P′—P′间有等电位线,房率250次,2:1(3:2)、4:1房室传导,P′—R0.16~0.24秒逐渐延长,呈交替性文氏周期。如此随呼吸的周期性周而复始的发生短暂性房速。附图B为吸屏后心电图,上行前段吸气时房速,屏气长达13秒出现
Case description Female patient, 39 years old, farmer. Due to chest tightness, palpitation, malaise 10 days admitted to hospital. No history of “cold” or “diarrhea” within 1 month before illness. Physical examination: little heart, arrhythmia, the average heart rate of 90 beats / min, precordial not heard and murmur. Two lungs (a). Laboratory tests: blood, anti “O”, ESR, SGOT, CPK, LDH and LDHS were normal. X-ray normal. ECG shows: sinus rhythm; brief paroxysmal atrial summon with alternated Wen’s cycle (see cover three). The figure shows the expiratory and sinus rhythm, inspiratory was a transient paroxysmal atrial rate, P’-P ’is equal, P’-P’ between the equipotential lines, room rate 250, 2: 1 2), 4: 1 atrioventricular conduction, P’-R0.16 ~ 0.24 seconds gradually extended, was Alternating Wen’s cycle. So with the cyclical breathing cycle occurs atrial tachycardia. Figure B for the suction screen after the electrocardiogram, ascending anterior chamber velocity, breath-hold up to 13 seconds appear
