This paper introduces a model of the atrioventricular node function during atrial fibrillation (AF), and describes the related ECG-based estimation method. The proposed model is defined by parameters ...

We report a case of a 50-year-old Caucasian male who was diagnosed with a 10.2 × 10.3 × 10.0 cm lower pole left renal mass in January 2002. Subsequently, he underwent radical left nephrectomy in ...

The AHA/ACC Foundation/Heart Rhythm Society recommendations for the standardization and interpretation of the ECG (2009) recommend selecting the electrocardiographic lead with the longest T wave when ...

Two different methods to elucidate the dependent or independent nature of the autonomic nervous system influence on the sinoatrial and atrioventricular nodes are considered. ECG PP and PR intervals ...

Objective: To establish gestational age-specific reference values of normal fetal atrioventricular (AV) time interval by spectral tissue Doppler imaging (TDI) and pulse-wave Doppler (PD) methods, and ...

BackgroundQT interval, measured through a standard ECG, captures the time it takes for the cardiac ventricles to depolarize and repolarize. JT interval is the component of the QT interval that ...

Therefore we selected the following biomarkers from the 12-lead ECG (QRS duration, QT dispersion, T wave amplitude, T peak to T end duration, and JT interval), the pressure-volume relationship (left ...
