Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). During the next 24 hours, she experienced periods of complete AV block with a ventricular escape rhythm in the 20s.
This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. They agreed ischemia was likely in the setting of demand given DKA and infection.
This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There is no definite evidence of acute ischemia. (ie, Some residual ischemia in the infarct border might still be present.
There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). This patient was having recurrent episodes of polymorphic ventricular tachycardia with an underlying long QT interval ( = Torsades des Pointes ). ECG #2 Interpretation of ECG #2: Underlying sinus rhythm.
There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus. [1] There is evolution from Wellens Pattern A to Pattern B, now inclusive of V6.
In the days before I learned to look for OMI, back when I was counting ST elevation boxes, I used to save ischemia for last.) This is sinus tachycardia (rhythm) with complete heart block (AV node function) with ventricular escape rate just below 30. Never forget that sinus tachycardia is the scariest arrhythmia.
ACUTE MI (I allowed Acute MI to be in the report because I knew there would be an elevated troponin from ischemia, which is the definition of acute MI -- but in this case it would most likely be a Type 2 MI from tachycardia) There is also LA-RA lead reversal. The November 27, 2021 post ( LA-RA reversal ).
This is critical for the EMS provider, or ED clinician, as identification of Grade I ischemia (aka, HATW’s) addresses the culprit lesion at the earliest opportunity with excellent downstream prognosis for the patient. [2] 2] But there is also Sinus Tachycardia! Chapter 6: Introduction to Myocardial Ischemia and Infarction.
After initiating treatment for hyperkalemia, repeat ECG showed resolution of Brugada pattern: The ECG shows sinus tachycardia. A Very Wide Complex Tachycardia. These include ( among others ) — acute febrile illness — variations in autonomic tone — hypothermia — ischemia/infarction/cardiac arrest — and Hyperkalemia.
There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. Here is a similar case: Collapse, Ventricular Tachycardia, Cardioverted, Comatose on Arrival. Agitation, Confusion, and Unusual Wide Complex Tachycardia. There is sinus tachycardia at ~115/minute.
During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). That said there were no clinical symptoms or ECG findings suggestive of ongoing ischemia. This patient very likely has some form of idiopathic ventricular tachycardia.
