We report a case of 26-year-old woman, with arrhythmic manifestation of peripartum cardiomyopathy with moderate heart failure. Ventricular arrhythmia recorded in ambulatory Holter ECG (premature ventricular contractions) was most severe during pregnancy, reduced when beta-blocker therapy was initiated and almost completely resolved after delivery. Then, 1 year after hospitalization in Cardiology Department, recurrence was observed with recorded short episode of nonsustained ventricular tachycardia.

We have previously shown that cyclosporine (CSA) counteracts cardiovascular manifestations induced by endotoxemia (lipopolysaccharide, LPS) such as hypotension and cardiac autonomic dysfunction in conscious rats. In this study we investigated whether the facilitation of central γ-amino butyric acid (GABA) neurotransmission blunts these favorable influences of CSA. The LPS-CSA interaction was determined in the absence and presence of drugs that activate GABAA or GABAB receptors or elevate synaptic GABA levels in the central nervous system...

BACKGROUND Poorly controlled ventricular rate associated with atrial fibrillation (AF) leads to tachycardia-induced left ventricular dysfunction. Atrioventricular (AV) nodal ablation and cardiac pacing is the standard of care in refractory congestive heart failure (CHF) due to AF with moderate to rapid ventricular response that failed conventional medical therapy. If the patient is not a candidate for AF ablation with pulmonary vein isolation and elimination of AF foci, this is an effective approach, but it does have some challenges when done in a patient with dextrocardia and situs inversus...

A 15-year-old girl of Asian origin, hailing from a rural agrarian background, presented with history of multiple episodes of dizziness for 3 years. The episodes were precipitated mostly by emotional and/or physical stress and relieved on lying down, with a few episodes culminating in transient loss of consciousness. As preliminary cardiac and neurological evaluation were normal, she was being treated by the primary physician as a case of probable psychogenic syncope, supported by the consistent association of the episodes with emotional stress...

BACKGROUND: A challenge in ICU EEG interpretation is identifying subclinical status epilepticus versus patterns on the ictal-interictal continuum versus other repetitive patterns. In the electrically noisy intensive care unit, identifying and eliminating interference and artifact allow accurate diagnoses from the EEG, avoiding unnecessary treatment or sedation. METHODS: We present a case during Impella (Abiomed Inc, Danvers, MA) continuous flow left ventricular assist device use where the EEG artifact was initially misinterpreted as seizure by the resident and treated as status epilepticus because of the "focal" sharply contoured repetitive pattern...

REVIEW

Most heart failure (HF) related mortality is due to sudden cardiac death (SCD) and worsening HF, particularly in the case of reduced ejection fraction. Predicting and preventing SCD is an important goal but most works include no or few patients with advanced age, and the prevention of SCD in elderly patients with HF is still controversial. A recent reduction in the annual rate of SCD has been recently described but it is not clear if this is also true in advanced age patients. Age is associated with SCD, although physicians frequently have the perception that elderly patients with HF die mainly of pump failure, underestimating the importance of SCD...

Pheochromocytomas are catecholamine-secreting tumors. These tumors are rare in children, and they may be associated with hereditary syndromes such as von Hippel-Lindau (VHL) disease. Most pediatric patients with pheochromocytoma present with sustained hypertension, while 10% to 69% of adult patients are asymptomatic. Herein, we present the case of a 12-yr-old Japanese girl with pheochromocytoma due to a germline mutation in the VHL (Arg161Gln). The only complaint was loss of weight. Pyrexia, anemia, and increases in C-reactive protein (CRP) and ferritin were observed...

A high dose of oral flecainide has been used for acute termination of atrial fibrillation (AF) and atrial flutter or intra-atrial re-entry tachycardia (AFL-IART) in adults. The use of flecainide for these conditions in children has not been well described. We describe our institutional experience on acute termination of AF or AFL-IART in children with a single high dose of oral flecainide in a hospital setting. All patients who received a single high dose of oral flecainide from 2009 to 2016 who were <21 years of age were included...

Idiopathic sustained focal right ventricular tachycardia (VT) is most frequently due to outflow tract (OT) tachycardia. This arrhythmia is recognized by its characteristic ECG pattern and sensitivity to adenosine. However, there are other forms of idiopathic, focal sustained VT that originate in the right ventricle (RV), which are less well appreciated and easily misdiagnosed. This review will identify the characteristic features and electrophysiologic properties of these forms of RV VT, including those originating from the tricuspid annulus, right ventricular papillary muscles and moderator band as well as variants of classic RVOT tachycardia and those due to microreentry in the presence of preclinical disease...

BACKGROUND: Multiform fascicular tachycardia (FT) was recently described as a ventricular tachycardia (VT) that has a reentrant mechanism using multiple fascicular branches and produces alternate fascicular VT forms. Ablating the respective fascicle may cause a change in the reentrant circuit resulting in a change in morphology. Ablation of the septal fascicle is crucial for successful treatment. OBJECTIVES: To describe four cases of FT in which ablation induced a change in QRS morphologies and aggravated clinical course...

Background: Whether nonsustained ventricular tachycardia (NSVT) is a marker of increased risk of sustained ventricular tachyarrhythmias (VTAs) remains to be established in patients receiving cardiac resynchronization therapy with a defibrillator (CRT-D) for primary prevention. Methods: Among the follow-up data of the Japan cardiac device treatment registry (JCDTR) with an implantation date between January 2011 and August 2015, information regarding a history of NSVT before the CRT-D implantation for primary prevention had been registered in 269 patients...

Ranolazine is a new medication for the treatment of refractory angina. However, except its anti-anginal properties, it has been found to act as an anti-arrhythmic. The aim of our systematic review is to present the existing data about the impact of ranolazine in ventricular arrhythmias. We searched MEDLINE and Cochrane databases as well clinicaltrials.gov until September 1, 2017 to find all studies (clinical trials, observational studies, case reports/series) reported data about the impact of ranolazine in ventricular arrhythmias...

OBJECTIVES: The application of atropine for pediatric sedation in the emergency department remains controversial. Our objective was to perform a comprehensive review of the literature and assess the clinical indexes in groups with and without atropine use. METHODS: PubMed, EMBASE, and the Cochrane Library were searched for randomized and non-randomized studies that compared ketamine and ketamine plus atropine for pediatric sedation. The risk ratio with 95% confidence interval was calculated using either a fixed- or random-effects model according to the value of I2 ...

In some patients with Kawasaki disease, a prior myocardial infarction causes ventricular tachycardia in the chronic post-myocardial infarction phase. We report the case of a 41-year-old man with symptomatic and haemodynamically unstable ventricular tachycardia in whom substrate ablation was performed for the ventricular tachycardia before insertion of an implantable cardioverter-defibrillator.

OBJECTIVES: Left ventricular ejection fraction (EF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are important surrogate markers of cardiac function and wall stress. Randomized trials of heart failure (HF) have shown improvements in survival in patients with reduced EF (<40%, HFrEF) but not with preserved EF (≥50%, HFpEF) or mid-range EF (40-49%, HFmrEF). Limited information is available on the trajectory of EF in contemporary heart failure management programs (HFMPs)...
