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.

The role of serum asprosin levels in predicting the severity of coronary artery disease in patients with diabetes mellitus.

Background: Asprosin is an emerging biomarker that plays a role in metabolic diseases. This study investigates asprosin as a predictive marker for coronary artery disease (CAD) severity in diabetic patients.

Methods: Diabetic patients (n = 181) and healthy controls (n = 60) were analyzed.

V1r + DIIq is a novel and accurate criterion to predict right vs. left paraseptal accessory pathways.

Purpose: The correct estimation of accessory pathway (AP) localization from surface ECG is critical before the procedure. Our study aimed to detect the predictive value of the V1r + DIIq criterion for differentiating right- from left-sided paraseptal APs.

Methods: We retrospectively included 58 patients with (Wolff-Parkinson-White) WPW syndrome and paraseptal APs who underwent successful catheter ablation (37 male, 21 female; mean age 34.

Relationship between coarse F waves and thromboembolic events in patients with permanent atrial fibrillation.

Background: The coarse F waves on the 12-lead surface electrocardiogram (ECG) in patients with atrial fibrillation (AF) are known as atrial viability and contractility indicator. Our aim in this study was to investigate the effect of coarse F wave on thromboembolism in patients with permanent AF.

Methods: In our study, 328 patients with permanent AF were included.

A new approach to radiofrequency catheter ablation of premature ventricular contractions: The diurnal variation index.

Background: Radiofrequency catheter ablation (RFA) is a frequently used method in the treatment of premature ventricular contractions (PVCs) resistant to drug therapy. RFA is recommended for patients with PVCs burden >10%. This study was aimed to investigate the presence of other parameters to enhance the indication of ablation in 24-hour rhythm Holter recordings.

Ischemic changes in lead aVR is associated with left ventricular thrombus or high-grade spontaneous echocontrast in patients with acute anterior myocardial infarction.

Objective: The aim of this study was to investigate the relationship between ischemic changes in the lead aVR and left ventricular thrombus (LVT) or high-grade spontaneous echo contrast (SEC) in patients with acute anterior myocardial infarction (MI).

Methods: Quantitative T wave polarity in lead aVR (TPaVR) and ST segment deviation in the lead aVR (STaVR) measured from a surface electrocardiogram (ECG), as well as the absolute numerical values, were recorded. The ST/TPaVR ratio was obtained by dividing the larger absolute value by the smaller.
