预激症候群也叫预激综合征又称吾、巴、怀综合征(W、P、W综合征),主要是由于房空间除正常的通路外,另有短路加速了房室间的传导,致使一部分心室肌预先发生激动,心电图主要表现为P-R间期缩短、QRS波增宽且在其起始部可见到预激波(图9-1),称为迭耳塔波(delta波)。这是由于窦房结到房室结的传导速度约为1000毫米/秒,但激动在房室交界区的传导速度约只有200毫米/秒,比较缓慢所致。故P-R间期正常在0.12～0.20秒。可是房空间的传导除正常途径外,还有三
Pre-excitation syndrome, also known as Wolff’s syndrome, also known as I, Pakistan, pregnant syndrome (W, P, W syndrome), mainly due to room space in addition to normal access, short circuit and accelerate the interventricular conduction, As a result, some of the ventricular myocardium was pre-excited. ECG mainly showed shortening of PR interval, widening of QRS wave and pre-shocking at its beginning (Figure 9-1), which was called delta wave. This is due to the sinus node to atrioventricular node conduction velocity of about 1000 mm / sec, but the activation of the junction in the AV chamber conduction speed of only about 200 mm / s, due to relatively slow. Therefore, P-R interval between normal 0.12 ~ 0.20 seconds. However, the transmission of room space in addition to the normal way, there are three
