Key result
Acute phase QRS fragmentation and Epsilon wave-like morphology in a patient with Takotsubo cardiomyopathy completely resolved after 3 months, accompanying the recovery of left ventricular function.
Why the study?
Whether fragmented QRS and Epsilon wave-like morphology have a prognostic role in Takotsubo cardiomyopathy remained unclear.
Case Report (n=1)
No
This case report demonstrates that QRS fragmentation and Epsilon wave-like morphology in Takotsubo cardiomyopathy can be transient and completely reversible upon recovery of left ventricular function.
No takes yet. Share an insight, caveat, or question.
Epsilon-like deflection in STEMI with troponin rise warrants ARVC consideration; leaves open systematic validation in larger cohorts.
Li et al. (2022) conducted a case report in Takotsubo cardiomyopathy (n=1). Takotsubo cardiomyopathy acute phase was evaluated on Resolution of QRS fragmentation and Epsilon wave-like morphology. Acute phase QRS fragmentation and Epsilon wave-like morphology in a patient with Takotsubo cardiomyopathy completely resolved after 3 months, accompanying the recovery of left ventricular function.
