I thought the complete lack of QTc prolongation and anatomic localization of ECG findings made Takotsubo cardiomyopathy unlikely. In fact, the ECG was described as normal, and without serial ECGs or prior ECGs for comparison it could be. Initial high sensitivity troponin I returned at 6ng/L (normal 0.20

During the night, while on telemetry, the patient became bradycardic, with periods of isorhythmic AV dissociation (nodal escape rhythm alternating with sinus bradycardia), and there were sporadic PVCs. There was hyperkinesis of the basal segments and findings were interpreted as typical of takotsubo cardiomyopathy. Learning points: 1.

Complete left bundle branch block (CLBBB)-like QRS morphology of right ventricular pacing at pacemaker implantation satisfying the American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society criteria of CLBBB was associated with development of pacing induced cardiomyopathy.

And of course Ken's comments at the bottom) An elderly obese woman with cardiomyopathy, Left bundle branch block, and chronic hypercapnea presented hypoxic with altered mental status. I do not see OMI here and all trops were only minimally elevated, consistent with either chronic injury from cardiomyopathy or with acute injury from sepsis.

A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension. The fact that he has a cardiomyopathy argues for a more typical ventricular tachycardia, as does the absence of rSR' in lead V1. It is regular.

It turns out that she has hypertrophic cardiomyopathy. Here is the echo report for this visit (after the negative angiogram): Hypertrophic cardiomyopathy with asymmetric septal hypertrophy. There was a question in the record of hypertrophic cardiomyopathy. Regional wall motion abnormality-distal septum and apex.

The overall rhythm is chaotic — which is not necessarily unexpected given the history of an acutely ill 12-year with severe dilated cardiomyopathy on Echo. There definitel are periods of bradycardia (so pacing may be needed for that). Hope this helps — :) ECG-3 — I see sinus bradycardia and arrhythmia.
