Conclusion Troponin elevation occurred in the majority of our patients after inappropriate ICD discharges secondary to lead fracture. This indicates that ICD shocks can cause myocardial injury.
Furthermore, cardiac magnetic resonance (CMR) images involving late gadolinium enhancement or LGE are being used increasingly to study the chronic scarring and myocardial injury that occurs in ...
This occurs because these ECG leads will see the MI backwards; the leads are placed anteriorly, but the myocardial injury is posterior. A R/S wave ratio greater than 1 in leads V1 or V2.
