    Lbbb with2:1 av block

    d

  3. Shyam Nv

    LBBB WITH 2:1av block with concordant T waves in LATERAL leads

  4. Shyam Nv

    Plus hyperkalemia also be ruled out

  5. Sanjay Natarajan

    Wide negative QS complexes from V1-V4 having LBBB morphology and 2:1 conduction of the Atrial impulses. P waves are of normal morphology and so the Pacer spikes can be ruled out.
    Hence, D) Left bundle branch block with 2:1 AV block

  6. Jerry Jones

    d) LBBB with 2:1 AV block
    Most likely this represents a Mobitz II AV block because of the LBBB unless there is a previous tracing demonstrating the same LBBB without a 2:1 block. There is a late transition in the precordium although no left axis deviation is present. The left-sided leads (I, aVL, V5, V6) show an inappropriate concordance of the QRS and T deflections indicating probable ischemic heart disease. The modified Smith-Sgarbossa calculations do not suggest any hidden STEMI.

    Ans is D. LBBB with 2:1 A.V Block

  10. Jyothi Vijay

    D
    Lbbb with 2:1 av Block.
    No evidence of of recent mi if lbbb is pre-existing (By Smith modified sgarbossa criteria or Cabrera notch or Chapman sign not seen).
    There is 2:1 conducting mobitz type 2 Av Block
