Angina Arrhythmia Ischemia

There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. It is a benign arrhythmia which requires no specific treatment. Possible mechanisms of ventricular arrhythmias elicited by ischemia followed by reperfusion. What is the rhythm?

A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.

This was clearly severe subepicardial ischemia causing ST Elevation, but it was not of a long enough duration to result in measurable infarct. Therefore this is " Transient ST Elevation Unstable Angina." As there was ruptured plaque, this is NOT Prinzmetal's angina. You can see the deficiency of the definition of MI.

The finding of all negative QRS complexes in leads V3-thru- V6 therefore strongly suggests that the arrhythmia-associated impulse is not traveling over an AP ( Steurer et al — Clin. ie, Severe subendocardial ischemia from sustained VT in a patient severe apical cardiomyopathy resulted in a peak troponin >31,000 ng/L in today's case ).

Relationship between Ischemia and arrhythmia While the relationship between Ischemia and VT is really complex, the term “Ischemic VT” itself adds more twists. Even here, it is the associated factors, like hypoxia or acidosis are the triggers which of course are resultant of Ischemia.
