conclusions male gender, history of hypertension, high nyha score, and the presence of cad predict lvef deterioration in patients with lbbb. objectives the present study aimed to identify underlying factors that predict left ventricular ejection fraction (lvef) deterioration in patients suffered from complete lbbb. patients and methods in a retrospective case-control study, the data of 220 cons...

conclusions both anesthetic regimens were acceptable for induction in patients with coronary artery disease and left ventricular dysfunction undergoing coronary artery bypass graft surgery. results incidence of pain on injection (2 - 4%) and myoclonus (10%) was less in both groups. the hemodynamic response was similar in the two groups for all variables over the time interval, except for ci at ...

In this article, dynamics of the cerebrospinal fluid (CSF) was studied, using computational fluid dynamics. Using MRI images of two special cases, a 2-dimensional model of the ventricular system was made. CSF velocity and pressure distribution in ventricular system have high importance since the flow pattern of this liquid has an important effect on intracranial pressure, i.e., ICP, which has a...

A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

introduction brugada syndrome (brs) is an autosomal-dominant inherited cardiac arrhythmia that occurs due to sodium channelopathy and increases sudden cardiac death due to episodes of polymorphic ventricular tachyarrhythmia. it is characterized by st-segment elevation in the right precordial leads and right bundle branch block (rbbb) pattern. we herewith present a case of brugada syndrome with ...

introduction: previous studies have indicated a relationship between mptp pore and av nodal rate-dependent properties. the aim of present study was to determine acute direct effects of cyclosporine on extracellular field potential of isolated rabbit av node during experimental atrial fibrillation. methods: in one group of male new zealand rabbits (1.5-2.5 kg) cumulative concentrations of cyclos...

cardiac involvement infrequently occurs in hypopituitarism, and lethal cardiac arrhythmias are rarely reported. we present a middle age female who died as a consequence of refractory ventricular arrhythmia whose medical history and previous laboratory investigation were consistent with hypopituitarism. we conclude that hypopituitarism may lead to electrocardiographic changes and malignant ventr...

background: the prevalence of patients with severe left ventricular dysfunction (lvd) referred for coronary artery bypass grafting (cabg) is increasing. preoperative lvd is an established risk factor for early and late mortality after revascularization. the aim of the present study was to assess the early outcome of patients with severe lvd undergoing cabg. methods: between december 2012 and no...

background: pulmonary arterial hypertension is a complication of most congenital heart diseases. we sought to assess the effect of sildenafil on patients suffering from pulmonary arterial hypertension in association with congenital heart disease on the basis of clinical and echocardiographic parameters and compare the catheterization and treatment results so as to evaluate the predictive value ...
