我们遇到3例由预激综合征引起的室上性心动过速,其中2例因用药不当,使病情加重,现报道如下。 例1男,27岁。1984年1月22日就诊。主诉:阵发性心慌1年余,每次发作持续20分钟左右自愈。本次发作持续时间约1小时。在某卫生所就诊,描记心电图为阵发性室上性心动过速,心室率162次/分。给予西地兰0.4mg+25％葡萄糖20ml静脉推注。3小时后仍感心慌、气短,并且出现胸前区憨闷感,送到急诊室就诊。当时心率180次/分,血压100/60mmHg,描记心电图诊为阵发性室上性心动过速。立即给予吸氧,在心电示波监护下,给予心律平70mg+25％葡萄糖20ml缓慢静脉注射。用药后2分钟,转为窦性心律,心率降至75次/分,律齐。心电图P-R间期0.08秒。
We encountered three cases of supraventricular tachycardia caused by Wolff-Parkinson’s syndrome, two of whom were exacerbated by improper medication, are reported below. Example 1 male, 27 years old. January 22, 1984 treatment. Chief complaint: Paroxysmal palpitation more than 1 year, each attack lasting about 20 minutes. The duration of this episode is about 1 hour. At a clinic, tracing ECG for paroxysmal supraventricular tachycardia, ventricular rate of 162 beats / min. To give cedilanfil 0.4mg + 25% glucose 20ml intravenous injection. 3 hours later still feel flustered, shortness of breath, and there is a sense of simplicity chest stuffiness, sent to the emergency room for treatment. At that time the heart rate 180 beats / min, blood pressure 100 / 60mmHg, tracings of electrocardiogram diagnosed as paroxysmal supraventricular tachycardia. Immediately give oxygen, ECG monitoring in the heart, given 70mg + 25% glucose flat glucose 20ml slow intravenous injection. 2 minutes after treatment, converted to sinus rhythm, heart rate dropped to 75 beats / min, law Qi. ECG P-R interval of 0.08 seconds.
