A 55 year old man has an ECG done. The QRS intervals are .15 secs with atypical patterns. The second heart sound is SPLIT. What is the LIKELY conduction defect? Is it First degree AV heart block or Mobitz Type I AV block or Mobitz Type II AV block?
A) This picture is diagnostic for "bundle branch block". (QRS interval > .12 secs and S2 split). SO, know that Mobitz II AV block is common here.
