- Current opinion in cardiology.Curr Opin Cardiol.2016 Jan;31(1):1-10. doi: 10.1097/HCO.0000000000000236.
- PURPOSE OF REVIEW: There has been a resurgent interest in frequent premature ventricular contractions (PVCs) led by the novel concept that they may be a potential cause of, or at least contribute to, cardiomyopathy. This review evaluates recent advances in our understanding of PVC-induced cardiomyop

- BACKGROUND: Our aim in this study was to estimate entrance skin doses (ESD) to patients who underwent catheter ablation procedures, by using a reference air-kerma (RAK) displayed on the monitor of an angiography system (displayed RAK).METHODS: The displayed RAK was calibrated which use of an air-ker
