BACKGROUND: Atrial fibrillation (AF) is a common arrhymia, and it results in increased risk of thromboembolism and decreased cardiac function. In patients undergoing cardiac surgery, concomitant radiofrequency ablation to treat AF is effective in restoring sinus rhythm (SR). This study is an observational cohort study aimed to investigate the safety and efficacy of bipolar radiofrequency ablation (BRFA) for treating AF combined with heart valve diseases. METHODS: Clinical data were analyzed retrospectively from 324 cases of rheumatic heart disease combined with persistent AF patients who underwent valve replacement concomitant BRFA...

BACKGROUND: Cardiac arrhythmia is an important complication of critically ill patients, especially in perioperative period and early after myocardial infarction. However, the information regarding this condition in medical critically ill without active coronary artery disease patients is limited. OBJECTIVE: To identify the predictive factors, incidence, and prognosis of tachyarrhythmia and bradyarrhythmia in non-coronary critically ill medical patients. MATERIAL AND METHOD: A single center prospective cohort study, included medical critically ill patients, age > or = 18 year-old, admitted in a 15-bed medical ICU between September 2010 and August 2011...

BACKGROUND: The primary aims of minimally-invasive cardiac valve surgery are to lessen the impact of the incision, extracorporeal circulation, myocardial ischemia, and pulmonary ischemia, to obtain satisfactory therapeutic results, and to allow a quicker rehabilitation. In this study, the feasibility of minimally-invasive mitral valve replacements without ascending aorta and vena cava cross-clamping under beating heart was evaluated by surveying 11 patients. METHODS: Preoperative risk factors, intraoperative techniques, and postoperative complications were surveyed and evaluated for one year (April 1, 2009 to March 30, 2010) in 11 patients who had undergone beating-heart mitral valve replacement surgery at The People's Hospital of Guangxi Zhuang Autonomous Region...

INTRODUCTION: For the past 40 years, methadone has been known to be an efficient treatment of substitution. Its use allowed a significant reduction in the mortality related to opioid addiction. Since 2001, many articles have reported some cases of syncope, wave burst arrhythmia, ventricular tachycardia due to prolonged QT interval and sudden death secondary to cardiac arrest, with a risk of prolongation of the QT interval above 440 ms (men) and 460 ms (women). Many explorations have helped in understanding the physiopathology by showing that opioids, including methadone, cause a blockage of the potassium channels of the gene HERG K+P...

BACKGROUND AND OBJECTIVE: Congenital complete atrioventricular heart block (CHB) is due to the lesion of the cardiac conduction system by specific transplacental antibodies of maternal origin. In adults with systemic lupus erythematosus (SLE), cardiac toxicity is very questionable and has been related to treatment with synthetic antimalarial drugs (AM). Here we evaluate, in our geographic area, the presence of non congenital CHB in adult patients with SLE and its possible association with AM treatment...

OBJECTIVE: To acquire more knowledge about neonatal lupus erythematosus (NLE). METHOD: Seven cases with neonatal lupus erythematosus who were seen in this hospital from 1990 to 2009 are reported in this paper and 87 cases reported previously from 1980 to now in China were reviewed. The clinical manifestations, serum autoantibodies, treatment and results of long-term follow-up are analyzed and summarized. RESULT: Totally 94 cases were summarized...

BACKGROUND: Shen song Yang xin (SSYX) is a compound of Chinese medicine with the effect of increasing heart rate (HR). This study aimed to evaluate its electrophysiological properties at heart and cellular levels. METHODS: The Chinese miniature swines were randomly assigned to two groups, administered with SSYX or placebo for 4 weeks (n = 8 per group). Cardiac electrophysiological study (EPS) was performed before and after drug administration. The guinea pig ventricular myocytes were enzymatically isolated and whole cell voltage-clamp technique was used to evaluate the effect of SSYX on cardiac action potential (AP)...

PURPOSE OF REVIEW: To describe the results of two recent prospective studies that may indicate how to monitor, diagnose, and treat fetuses with neonatal lupus manifesting with heart involvement and to summarize additional research reports regarding the pathophysiology and outcomes of this rare condition. RECENT FINDINGS: The PR Interval and Dexamethasone Evaluation study found 10 cases of neonatal lupus (10%) with three first-degree atrioventricular blocks (AVBs) and three complete heart blocks...

Cystic tumor of the atrioventricular nodal region is a rare cardiac primary tumor that can cause heart blockage and sudden death. Antemortem diagnosis and successful excision of the atrioventricular nodal region are extremely rare. A 41-year-old woman who presented with dyspnea and palpitations is reported. Electrocardiography revealed third-degree atrioventricular block. Echocardiography showed a right atrial cystic mass attached to the interatrial septum. The patient underwent surgical excision of the mass...

Cardiac myxomas are rare benign tumors of the heart. The growth rate of these tumors remains unknown. Right atrial myxoma can simulate nonspecific constitutional symptoms, such as remittent or lasting fever, weight loss, and chronic anemia, and may escape timely diagnosis until the development of severe complications such as pulmonary hypertension due to embolism from fragments originating from the tumor mass or blockage of the right atrioventricular ostium or Budd-Chiari syndrome with acute abdominal pain...

PURPOSE: To evaluate the parameters of dogs anesthetized by different dissociative drugs protocols through continuous intravenous infusion. METHODS: Thirty healthy dogs of both sexes were assigned randomly to three groups (G1, G2, and G3). G1 was administered with methotrimeprazine as a pre-anesthetic medication, intravenously midazolam-ketamine as bolus for induction and midazolam-ketamine by continuous intravenous infusion for a 60 minute-period of maintenance...

The goal of this research was to study influence of the MS on the electrophysiological parameters of the heart conduction system. The research involved 32 patients suffering from heart arrhythmias (18 females and 14 males, average age 52,8-/+12,9). The patients were categorized into 2 groups. Group I included 15 patients (9 females and 6 males, average age 47,5-/+8,9) suffering from heart arrhythmias and with signs of MS. Group I was subdivided into 2 subgroups: I subgroup--10 patients without diabetes, and II subgroup 5 patients with type II diabetes...

The cardiovascular effects and toxicity of tricyclic antidepressants (TCAs) have been well documented in medical literature. The most common manifestation of such effects is slowing of intraventricular conduction, manifested by prolonged PR, QRS and QT intervals on the standard electrocardiogram (ECG) and postural hypotension. In contrast to TCAs, selective serotonin reuptake inhibitors (SSRIs), including fluoxetine and citalopram, are considered to cause less effect on cardiac impulse conduction. In addition, these compounds induced significantly less anticholinergic, antihistaminergic and cardiotoxic side-effects than TCAs...

Late cerebral vasospasm after subarachnoid hemorrhage (SAH) is a disastrous phenomenon for the patients and a definite treatment has not been established. We studied 48 consecutive patients receiving high-dose diltiazem (5 micrograms/kg/min) injection combined with dextran and hydrocortisone to late cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). All but 2 patients underwent surgery within 72 hours after SAH. Diltiazem was continuously given via a central venous line for up to 2 weeks in conjunction with simple cisternal drainage...

Eighteen patients under went surgical treatment of univentricular hearts between April 1989 till October 1992. All 18 had palliative operations in the form of: a modified Blalock-Taussig shunt (5), pulmonary artery banding (2), bidirectional Glenn shunts (2), conventional Fontan repair (1) and total cavo pulmonary connection (8). There were 11 males and 7 females. The mean age at operation was 4.5 years (range, 1 month to 24 years). The average weight at operation was 12.2 kg (range 2 to 43 kg). Associated anomalies included: transposition of the great arteries (4), pulmonary stenosis (9), pulmonary atresia (1), mitral atresia (1), atrioventricular septal defect (1) and patent ductus arteriosus (3)...
