BACKGROUND Contractile discordance exacerbates cardiac dysfunction, aggravating heart failure outcome. Dissecting the genesis of mechanical dyssynchrony would enable an early diagnosis before advanced disease. METHODS AND RESULTS High-resolution speckle-tracking echocardiography was applied in a knockout murine surrogate of adult-onset human cardiomyopathy caused by mutations in cardioprotect...
Background: In addition to heart disease, ECG also changes in non-heart disease, which due to its similarity, can lead to misdiagnosis of heart disease in patients. ECG changes in brain lesions such as ischemic and hemorrhagic strokes, brain traumas, etc. and have been studied in many articles, but the effects of brain midline shift on ECG changes have not been studied. In this study, we want t...
at first, in order to define acute toxicity of diazinon insecticide and butachlor herbicide, acute toxicity tests (lc5096h) were done, based on standard method (1989) o.e.c.d. in static way and for 96 hours. and the amount of acute toxicity (lc5096h) of diazinon and butachlor in 1 to 2 gram vimba vimba persa fry larva was determined to be 0.09 and 0.61 respectively. in order to do histology stu...
INTRODUCTION Previous studies have raised the probably of cardiac manifestation in tramadol poisoning. However, conclusive information on electrocardiographic (ECG) abnormalities of tramadol overdose remains to be explained. Therefore, the present study aimed to evaluate the epidemiology of ECG abnormalities in tramadol poisoned patients. METHODS In a prospective cross-sectional study, all pa...
Torsade de pointes, also called atypical ventricular tachycardia (AVT), was diagnosed in 10 patients, nine on antiarrhythmic therapy and one with acute central nervous system damage. Four patients received quinidine and five disopyramide, either alone or in combination with amiodarone. AVT was dose-dependent in some, but in others, it started shortly after initiation of drug therapy (idiosyncra...
Implantable cardiac pacing systems are a safe and effective treatment for symptomatic irreversible bradycardia. Under the proper indications, cardiac pacing might bring significant clinical benefit. Evidences from literature state that the action of the artificial pacing system, mainly when the ventricular lead is located at the apex of the right ventricle, produces negative effects to cardiac ...
