一、综合征患病态窦房结综合症(简称ss综合症)病人的平均年龄约65岁,很多病人出现由间歇性心动过缓所致的多次眩晕发作或晕厥,一些病人出现由阵发性心动过速引起的心悸或心绞痛。过缓性心律失常包括:暂短的窦性停搏或持续的不适宜的窦性心动过缓,阿托品对其无效。有些病人还可以看到Ⅰ°房室传导阻滞或间断性更高度的房室传导阻滞。在正常的心脏中,自律性存在于窦房结、房室结和浦肯野氏系统的细胞内。在ss综合症所见的心动过缓的特性,进一步证明:自律性的障碍不仅限于窦房结内,还影 First, the syndrome of sick sinus syndrome (SS syndrome) The average age of patients about 65 years old, many patients appear intermittent bradycardia caused by multiple episodes of vertigo or fainting, some patients appear by the array Heart palpitations or angina caused by tachycardia. Cesarean arrhythmias include: short sinus arrest or persistent inappropriate sinus bradycardia, atropine invalid. Some patients can also see Ⅰ ° atrioventricular block or intermittent more atrioventricular block. In the normal heart, autonomy exists in the cells of the sinus node, atrioventricular node, and Purkinje system. The syndrome of bradycardia seen in the syndrome of SS further confirms that the disorder of self-regulation is not limited to the sinus node,
