She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Are you confident there is no ischemia? Primary VT , and the VT with tachycardia is causing ischemia with chest discomfort (supply-demand mismatch/type 2 MI)? The last echocardiography 12 months ago showed HFmrEF.

It is also unique because it works using the Doppler effect, you can get not only an anatomical evaluation of the heart but also physiological assessment. Some patients with pacemakers and metal prosthesis can’t be exposed to such strong magnetic fields. It is still possible to have ischemia without coronary disease.

Isoprenalin was discontinued, and a temporary transveous pacemaker was implanted. The patient stabilized following pacemaker placement. Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). The QRS complex in ECG #1 is wide.

No evidence for ischemia jumps out. How does a pacemaker accomplish RBBB morphology? Quick aside on device terminology (feel free to skip): A "single chamber" pacemaker is a device with only one lead. A "dual chamber" pacemaker is a device with an atrial lead and a ventricular lead. ECG 1 What do you think?

Evidence of acute ischemia (may be subtle) vii. Negative predictors of adverse outcome: Pacemaker Pre-syncope or "near-syncope," but there is still some small risk (5, 18) These last two are identified in studies, but I consider them dangerous signs and symptoms in their own right, as above: 10.

It is possible there is microvascular dysfunction producing residual transmural ischemia. But this is most common when there is prolonged ischemia, and this patient had the fastest reperfusion imaginable! With regard to the Physiologic Chain Reaction As per Dr. Frick We do not have all the answers.
