Effect of direct adrenaline infusion into isolated rat heart on the induction of ventricular tachyarrhythmias

Popis výsledku v původním jazyce

In this study, hearts from 72 male Wistar albino rats were divided into two main protocols: a 40 min ischemia group (protocol A, n = 53) and 10 min ischemia group (protocol B, n = 19). Protocol A subdivided into 2 groups as a control group ( n = 10) and adrenaline group ( n = 43). Protocol B is subdivided into 2 groups as control group ( n = 10) and adrenaline group ( n = 9). Both adrenaline groups received the same dose of adrenaline.&lt;br /&gt; In protocol A, ventricular tachyarrhythmia (VTA) incidence was 0 % in controls but rose to 72 % in the adrenaline group ( p &lt; 0.01). Heart rates for the control and adrenaline groups in stabilization and reperfusion were 254 +/- 45 bpm and 247 +/- 66 bpm, versus 277 +/- 41 bpm and 651 +/- 286 bpm, respectively.&lt;br /&gt; In protocol B, VTA incidence reached 100 % in both groups during reperfusion, with heart rates of 393 +/- 29 bpm and 892 +/- 227 bpm for controls and 350 +/- 49 bpm and 949 +/- 116 bpm for the adrenaline group.&lt;br /&gt; These findings suggest that direct adrenaline administration into the heart in last 5 mins of the ischemic period and the 5 mins of in the reperfusion time increases the incidence of reperfusion-induced ventricular arrhythmias up to 72 % in protocol A. Protocol B hearts showed reperfusion-induced ventricular arrhythmias with 100 % incidence in both groups.
