Nerol Attenuates Ouabain-Induced Arrhythmias

Figure 4

Nerol attenuates cardiac arrhythmias and electrocardiographic (ECG) alterations induced by ouabain. (a) Representative ECG recordings with 50 μM ouabain (Ouab) evoking the occurrence of ventricular premature beatings (VPB), ventricular tachycardia (VT), and ventricular fibrillation (VF). (b) Arrhythmias score and (c) occurrence of arrhythmias (VPB, VT, VF). ECG parameters: PR interval (d), QRS complex (e), and QTc interval (f). Data are represented as means ± SEM (n = 4-7, p<0.05 versus control, # p<0.05 versus ouabain). One-way ANOVA followed by Tukey’s post hoc test. Chi-squared test (c).
