Abstract Background Programed ventricular stimulation (PVS) is a risk stratification tool in patients at risk for adverse arrhythmia outcomes. Patients with negative PVS may yet be at risk for adverse arrhythmia-related events, particularly in the presence of symptomatic ventricular arrhythmias (VA).

IMPRESSION: The finding of sinus bradycardia with 1st-degree AV block + marked sinus arrhythmia + the change in PR interval from beat #5-to-beat #6 — suggests a form of vagotonic block ( See My Comment in the October 9, 2020 post in Dr. Smith's ECG Blog ). Initial high sensitivity troponin I returned at 6ng/L (normal 0.20

The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy. The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy. Potassium was 4,8 mmol/l. ( ref 3,5-4,6 mmol/l ).

Enlargement of the left ventricular cavity, increased wall thickness and increased trabeculations in athlete’s heart will have to be differentiated from conditions like dilated cardiomyopathy, hypertrophic cardiomyopathy and isolated left ventricular non-compaction.

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. I added, "Makes me wonder if this could be myocarditis in a younger adult — maybe even with sinus arrhythmia."

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.
