In vivo cardiac electrical activity of nitric oxide in barium chloride treated male rats

The aim of this study was to evaluate the effects of nitric oxide in barium chloride (BaCl2)-induced arrhythmia in male albino rats. 10mg/kg/hr of BaCl2 was infused intravenously through caudal vein to induce arrhythmia, to ameliorate this effect 1mg and 10mg/kg/hr of sodium nitroprusside (SNP; nitr...

Description
Summary:The aim of this study was to evaluate the effects of nitric oxide in barium chloride (BaCl2)-induced arrhythmia in male albino rats. 10mg/kg/hr of BaCl2 was infused intravenously through caudal vein to induce arrhythmia, to ameliorate this effect 1mg and 10mg/kg/hr of sodium nitroprusside (SNP; nitric oxide donor) were infused, respectively. The ECG signals and parameters were recorded and analyzed with the aid of BioAmp of ADInstruments data acquisition system and Labchart software. The results showed that infusion of both 1mg/kg/hr and 10mg/kg/hr of SNP non significantly changed heart rate (BPM), QRS interval (s), S amplitude (mV), T amplitude (mV), ST height (mV), JT height (mV), QT intervals (s) and QTc (s). In conclusion the results of the current study indicate that SNP cannot ameliorate arrhythmia-induced by BaCl2.
