小公司很多都是2个专门对付FDA,2个搞市场,1个engineer。去年我们这行一个大公司
被FDA搞的所有的人停下手里的活,做documentation,持续了接近半年的样子。
血糖仪和三聚氢胺的检测仪原理差不多不错,可是sensor不一样啊。其他的电路谁都会
做,可是这个sensor就复杂了去了。不是说做就做出来的。要不然血糖监测仪就都带其
他功能,什么铁啊,钙啊什么的通通监测一番了。医院里面的各个lab也都可以关门了。
EEG, ECG做无线很容易,毕竟一维数据,没有多少数据量。我认得几个人,学期
project就是做这个,用的zigbee,也没有什么干扰的问题,好像最后结果还不错。只
是这个东西太关键,还是连电线稳定啊。万一呢,对吧。
进来医学仪器也不景气,obama 闹的,各个医院不买仪器了。我们这行最大几个公司现
在都不招人了(不过说是这么说,实验室刚毕业的几个都进去了)。 |

called concealed AP and couldn't demonstrate preexcitation on a standard

preexcitation after administration of antiarrhythmic drugs like procainamide

Anyway, still be very cautious in PSVT in known WPW patients---- try to
avoid AV nodal blockers.

Dreamtrue及各位:
你很关心的问题的问题:WPW窄QRS PSVT的时候,可不可以选Adenosine?是不是要小心。
答案:可以选Adenosine,但还是要小心!
关于WPW,正确的说法应该是:静息时,旁道100%前传,程度不同而已,所以我们才凭ECG诊断WPW。因为90%左右旁道的传导速度和不应期是比较固定的,理解为90%的旁道其“电阻”是固定的;对AVN,它的不应期和传导速度和可变的,受神经内分泌的影响较大,所以,delta波的幅度和宽度,PR缩短的程度,是经常变化的。
在PSVT发作的时候,90%左右仍然是AVN前传,旁道逆传(也许是我丢了将近5年了,也许是我写的时候太想强调用“单独阻断AVN的药物一定要小心”,反正错了,我认!——好在没有被Wangking抓住,嘿,嘿!这也是多年前我老师觉得我太轻浮(不是传统的“风花雪月”那种意义,是指不踏实的意思!),最后只能由他亲自出面,把我的高级职称当场拿掉的原因之一吧!也因为这个,我才拒绝国内“高薪聘请”,毅然漂泊美丽坚,扯远了!)。

迟复为歉!
你的想法是正确的。
三个术语从不同的角度和水平,来定义一些电生理过程和概念。
AP, 是指单个心肌细胞的电活动过程,主要用于单个细胞。
ERP,用于1:单个心肌细胞,:2:特定的传导组织。在单个心肌细胞,ERP是指在一次
AP或者说一次兴奋过程中,从0期去极到复极至-60mV左右这个时期内,无论再给心肌细
胞多大的刺激,不可能引起另一次AP;在临床电生理检查中,主要指我们给了特定的刺
激后,组织无反应的情况,如房室结的ERP、旁道的ERP等等。因此,ERP既是一个细胞
电生理的概念,又是一个临床电生理中的重要概念——我们做完射频消融(RFCA)后,
就得在病历上反复写ERP这些参数。
QT间期,是ECG上反映的、心室的总体电活动——我们知道,心脏是通过润盘这种东西
连在一起的、同步电-机械活动的一个合胞体。
这里,“心肌细胞”是指任何可兴奋的心脏组织中的细胞,不单指工作细胞。
还有个概念:单向动作电位(MAP),是指用一个比较大的电极,在心外膜上记录到的
、多个心肌细胞的、综合的动作电位。其意义和在单个心肌细胞记录到的AP的意义相同。
