Secret signal delayed mapping in patients with premature ventricular contractions.

Introduction: Mapping and radiofrequency ablation (RFA) of premature ventricular contractions (PVC) that show diurnal changes during the day, and which are rare during 3-D mapping has become very difficult. The most delayed signal mapping in the right ventricular outflow tract (RVOT) with RV apical pacing might be useful in these situations and we called this method Secret Signal Delayed Mapping (SSDM).

Aim: To compare the classical RFA and SSDM in patients with PVC.

Impact of HATCH Score on the Development of No-Reflow Phenomenon in Patients With ST-Segment Elevation Myocardial Infarction.
