Does Atropine work on a 3rd degree HB? - EMTLIFE
网页2011年9月11日 · Unfortunately, in a complete 3rd degree block atropine may accelerate the SA node, noted as an increase in P wave activity, but since the ventricular rate is initiated by the purkinje fibres, an increase in SA nodal activity will have no effect. This is why pacing is the treatment of choice.
Differentiating Heart Blocks (For Medic Students) - EMTLIFE
网页2009年1月12日 · If Consistent the heart block can only be a 1st degree block or a 2nd degree Mobitz II. If you have one p-wave with just a long interval then it is first degree. If you have more than one "p" but the interval is consitent, it is 2nd degree type II. If Inconsistent, the heart block can only be 2nd type I, or 3rd degree.

Chest Pain Case | EMTLIFE
网页2016年10月26日 · Given that the patient developed a 2nd degree, type II AVB, I would probably have foregone anything along the lines of atropine and instead set up for immediate TCP if the patient converted into a 3rd degree or became symptomatic. OP: I also have to echo Summit here too.
Cardiac arrhythmias help? | EMTLIFE
网页2016年1月15日 · I've heard that 2nd degree AVB type II (Mobitz), 3rd degree AVB, or patients with heart transplant do not respond to atropine. There are many criteria used to differentiate VT vs SVT with aberrancy. The most common one I've seen used or discussed is Brugada's criteria. Step 1 Are there any RS complexes in the precordial leads (leads …

网页2008年4月23日 · In actuality is not a "heart block" rather an A-V dissociation (it is doing its job too well). The reason I shudder when I hear the term "heart block"; and those that presume 3'rd degree is the worse block; when in reality 2'nd degree type II has a higher mortality rate (precursor to lethal AMI's).
