CPR Second Degree Heart Block

By | June 30, 2014

Classic Second Degree Heart Block (Mobitz Type II) The AV NODE selectively conducts some beats while blocking others. Those that are not blocked are conducted through to the ventricles. Once in the ventricles conduction proceeds normally.

Second-degree AV block type I (Mobitz I, or Wenckebach) = progressive lengthening of the PR interval with dropped QRS complexes. minutes prior to CPR. The heart has probably used up most of the available oxygen needed to contract effectively.

Type I second-degree heart block, commonly known as Wenckebach, is defined as progressive PR prolonga-tion until a QRS complex is entirely dropped. CPR is not necessary in a patient who has a palpable pulse, albeit bradycardiac and weak.
