Epicardial Origin
Whole-cell voltage-clamp experiments and single-channel current recordings in cell-attached patch mode were performed on enzymatically dissociated single ventricular myocytes harvested from feline endocardial and epicardial surfaces. The studies were designed to compare the characteristics of inward rectifier K' current (IK1) and delayed rectifier K' current (IK) between endocardial and epicard...
متن کاملCardiac regeneration: epicardial mediated repair
The hearts of lower vertebrates such as fish and salamanders display scarless regeneration following injury, although this feature is lost in adult mammals. The remarkable capacity of the neonatal mammalian heart to regenerate suggests that the underlying machinery required for the regenerative process is evolutionarily retained. Recent studies highlight the epicardial covering of the heart as ...
متن کاملElectrocardiographic recognition of the epicardial origin of ventricular tachycardias.
BACKGROUND Some ventricular tachycardias (VTs) originating from the epicardium are not suitable for endocardial radiofrequency ablation and require an epicardial approach. The aim of this study was to define the ECG characteristics that may identify an epicardial origin of VTs. METHODS AND RESULTS We analyzed the 12-lead ECG recordings during epicardial and endocardial left ventricular pacing...
متن کاملHow To Identify & Treat Epicardial Origin Of Outflow Tract Tachycardias.
The right ventricle outflow tract (RVOT) is the most common site of origin of idiopathic ventricular arrhythmias. The typical outflow tract arrhythmias pattern on ECG is an inferior axis deviation and left bundle branch block when originated on the RVOT and right bundle branch block morphology when originated on the left ventricular outflow tract (LVOT). There are several ECG tricks for differe...
متن کاملHow to Recognize Epicardial Origin of Ventricular Tachycardias?
Percutaneous pericardial access for epicardial mapping and ablation of ventricular arrhythmias has expanded considerably in recent years. After its description in patients with Chagas disease, the technique has provided relevant information on the arrhythmia substrate in other cardiomyopathies and has improved the results of ablation procedures in various clinical settings. Electrocardiographic...
