2013 Bradycardia Ischemia

Even if we stopped here — We could conclude the following: There is marked bradycardia in today's rhythm ( ie, Heart rate in the low 30s ). Finally — If today's patient does not have significant underlying coronary disease — then her bradycardia with AV block may be the result of SSS ( S ick S inus S yndrome ).

That said — obvious findings include: i ) Marked bradycardia! — This suggests ischemia of uncertain duration. Section 20 ( 54 pages = the " long " Answer ) from my ACLS-2013-Arrhythmias Expanded Version provides detailed discussion of WHAT th e AV Blocks are — and what they are not ! be regular! —

Here is his ECG: There is no clear evidence of OMI or ischemia. The Initial ECG in Today's Case: ECG #1 showed sinus bradycardia at a rate slightly under 60/minute — normal intervals — slight left axis ( about -15 degrees ) — and no chamber enlargement. A 40-something male with no previous cardiac disease presented with chest pain.

Followup ECG: No Change Absence of evolution is the best evidence against ischemia as the etiology. I was taught that the tell-tale sign of ischemia vs an electrical abnormality was in the hx, i.e. chest pain for the ischemia and potential syncope for brugada. Ischemia/infarction. Bradycardia. Hypothermia.

Hyperkalemia causes peaked T waves and the "killer B's of hyperkalemia", including bradycardia, broad QRS complexes, blocks of the AV node and bundle branches, Brugada morphology, and otherwise bizarre morphology including sine wave. With a twist. Do you recognize this ECG yet? Right Bundle Branch Block with ST Elevation in V1?

This definition was changed following an expert consensus panel in 2013 — so that at the present time, all that is needed to diagnose Brugada Syndrome is a spontaneous or induced Brugada-1 ECG pattern, without need for additional criteria.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI. It is possible there is microvascular dysfunction producing residual transmural ischemia. He told the patient this horrible news. The other point in favor of RCA is junctional rhythm.
