Tachycardia is common in the pediatric age group. The most commonly seen arrhythmias in children are sinus tachycardia. However, supraventricular tachycardia is the most common tachyarrhythmia that necessitates treatment. Ventricular tachycardia is rare in healthy children but may be associated with sudden cardiac death.  The important risk factors that predispose children for arrhythmias inclu...

Cardiac arrhythmias, caused by disorders in the generation and transmission of cardiac impulses, is included among the heart disorders that cause inefficient blood circulation. The most commonly-used method for diagnosing this disorder is electrocardiography. In this study, we aimed to identify and diagnose different types of arrhythmia prevalent among the seemingly-healthy horses of Sanandaj C...

Background & Aims: This study was carried out to assess the effect of opium addiction on the incidence of different types of arrhythmias after acute myocardial infarction (AMI). Methods: The study population consisted of 200 patients with first AMI admitted within 6 hours of the onset of chest pain to the coronary care units (CCU) of two hospitals affiliated to Kerman University of Medical Scie...

adonis aestivalis (summer pheasant-eye) is an annual plant with a crimson flower, distributed in southern europe and asia. the plant has large buttercup-like blossoms and soft, fern-like leaves. it blooms in spring and is often found as a weed in cereal fields. like other adonis spp., the plant produces cardiac glycosides. it is used in remedies for mild weakness of the heart, especially when a...

abstract introduction: resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. the aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% o2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. methods: following 60 and 180 minutes of hyperoxia, rat hearts wer...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...

background: myocardial ischemia is one of several causes of prolonged qt dispersion. the aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina. methods: we assessed the effects of full revascularization in patients with chronic stable angin...

genetic basis of diffrent arrhythmias has always been an intresting subject of resesrch for scientists. here i will review in brief the most common familia arrhythmias and the new findings regarding their mode of inhetitance. this paper will mainly focus on the genetic basis of the long qt syndromes but we will also have a short review of the genetics of three other familia congenital arrhythmo...
