Prediction of the supraventricular arrhythmias in hypertensive patients with different forms of the left ventricular geometry

Left ventricular hypertrophy (LVH) in course of hypertension has been linked to the development of atrial fibrillation (AF) and other supraventricular arrhythmias (SVA). The aim was to discover the predictors of electrical instability which could identify hypertensives with the risk of SVA and to investigate the role of different types of left ventricle (LV) geometry on the risk of arrhythmias. The second aim was to evaluate two types of filtering of signal-averaging ECG in the prediction of cardiac arrhythmias in hypertensive patients. Statistical analysis including generalized additive models (GAM) were performed. Maximum heart rate (HRmax), duration of P-wave in Butterworth filtered atrial SAECG (hfP_S), envelope of the last 10 ms P-wave vector magnitude (obw10_S) and left atrial internal area (LAar) were identified as the model of SVA predictors.
