this report describes a 55-year-old woman in whom yellow scorpion sting resulted in the development of mobitz type 1 and transient complete heart blocks unresponsive to atropine administration.  it might be concluded that although autonomic involvement including parasympathetic overactivity is present in such cases, other factors such as toxic damage to the cardiac conduction system may play a ...

Introduction:Severe abdominal aortic constriction above the renal arteries induces arterial hypertension above the stenotic site that is the cause of cardiac hypertrophy. Previous studies have shown that high blood pressure induces myocardial oxidative stress with conflicting results. In the present study, we assessed the effects of acute hypertension on the myocardial oxidative stress an...

the cardiac action of phenoxybenzamine (dibenzyline) was studiedusing the maximum rate of pressure rise in the left ventricle as a measure of myocardial contractility. cardiac function was assessed by increasing the pressure load on the heart and measuring contractility as reflected by dp/dt. dibenzyline was found to change the cardiac response to pressure load. the rate of pressure increase in...

Although lightning is an uncommon phenomenon in nature; it can cause many destructive incidents. In the event of a lightning strike, multiple organs particularly the cardiovascular systems are at risk of injury. Short-term mortality depends on its cardiac effects. In this paper, the authors report the development of myocardial infarction and pericardial effusion after lightning injury, a typica...
