background: the cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. this study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. methods: five groups (7 each) of male sprague-dawley rats, including a control group, a diabetes (induced by streptozocin and nicotinamide)...

conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

Background: The outbreak of coronavirus disease 2019 (COVID-19) has become a global crisis, as the World Health Organization (WHO) declared COVID-19 as a global pandemic. Complete heart block, resulting from an abnormal heart rhythm, is a rare presentation of this infection, which can be life-threatening due to possible progression into ventricular tachycardia. Case Presentation: We report a c...

OBJECTIVE To review the importance of heart rate variability analysis in left ventricular dysfunction and heart failure and to assess the effects of drug treatment. In patients with left ventricular dysfunction or heart failure, a low heart rate variability is a strong predictor of a low probability of survival. Because drug treatment in these patients has rapidly changed over the past two deca...

BACKGROUND There are very few published studies of heart disease in HIV infected children living in sub-Saharan Africa, a region with more than 50% of the world's population of HIV infected patients. OBJECTIVES To determine the prevalence, and describe the type and clinical presentation of heart disease among children with HIV attending an ambulatory clinic. METHODOLOGY Two hundred and thir...

This study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. During 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free Krebs-Henseleit solution (control) or the solution containi...

Ventricular tachycardia is rare in children. In the absence of structural heart disease, ventricular tachycardia is known as idiopathic ventricular tachycardia and carries a good prognosis. We report a 14-month-old male child with right bundle branch block incessant ventricular tachycardia without structural heart disease. In this patient ventricular tachycardia was controlled by amiodarone and...
