2014 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 2F ( 6 pages = the " short " Answer ) from my ECG-2014 Pocket Brain book provides quick written review of the AV Blocks. be regular! — I supplement this material with the following 2 PDF handouts.

Sinus bradycardia, normal conduction, normal axis, normal R wave progression, no hypertrophy. 2] Here there is no posterior ST elevation, but the anterior ST depression is also less—so it is dynamic, confirming acute ischemia. What do you think? But it is still STEMI negative.

2] Conduction through the accessory pathway can be intermittent (with different degrees of pre-excitation), and affected by ischemia. 3] So a patient with WPW can have the pattern induced by ischemia, and there is also a report of a patient with pre-existing WPW which was “ablated” by myocardial infarction after an LAD occlusion.[4]

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.
