NPPB and ventricular tachycardia: Regarding the association of biomarkers with different pathological patterns on ECG and Holter, we found statistical significance for pathological Q wave (p = 0.029, F = 5.057), complex PVCs (p = 0.034, F = 4.857), ventricular tachycardia (p = 0.048; F = 4.167) and NT-proBNP (Figure 1 and Figure 2).
