BACKGROUND: The accuracy of blood pressure measurement is variable in office-based settings. Even when staff training programs are effective, knowledge and skills decay over time, supporting the need for ongoing staff training. We evaluated whether a web-based continuing education program in blood pressure measurement reinforced knowledge and skills among clinical staff and promoted sustainability of an existing quality improvement program. METHODS: Medical assistants and nurses at six primary care clinics within a health system enrolled in a 30-min online educational program designed to refresh their knowledge of blood pressure measurement...

Aims: Cardiac death is the leading cause of mortality in patients with sarcoidosis, yet cardiac involvement often remains undetected. Cardiovascular magnetic resonance imaging (CMR) and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) have been used to diagnose cardiac sarcoidosis (CS) yet never simultaneously in a cohort. This study sought to assess the diagnostic and prognostic utility of simultaneous hybrid cardiac PET/MR. Methods and results: Fifty-one consecutive patients with suspected CS (age 50 ± 13 years, 31 males) underwent simultaneous PET/MR following a high-fat/low-carbohydrate diet and 12-h fast...

BACKGROUND: Short-term and long-term exposure to prolonged sitting is associated with excess food intake and weight gain in children. Interrupting prolonged sitting with low-intensity activity has been shown to not alter hunger, satiety, or food consumption in children, however it is unclear whether interrupting sitting with high-intensity activity will alter appetite regulation in children. PURPOSE: The purpose of this study was to examine the acute effects of interrupting prolonged sitting with intermittent activity performed at varying intensities on hunger, satiety, prospective food consumption (PFC), and food intake in preadolescent children...

Introduction: Spinal anesthesia is preferred technique of choice in infraumbalical surgeries. Limitation of this technique is shorter duration of analgesia, so various adjuvants have been used with intrathecal bupivacaine such as fentanyl, clonidine, and dexmedetomidine. Dexmedetomidine is a highly selective alpha 2 adrenergic agonist. The aim of our study was to know the effect of different doses of dexmedetomidine on intrathecal bupivacaine. Materials and Methods: The prospective, randomized, double-blind study was conducted in tertiary health care center, on ninety patients of the American Society of Anesthesiology Class I and II, of age group 18-60 years of either sex...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is an increasingly prevalent therapy in patients with severe symptomatic aortic stenosis. Conduction disturbances requiring permanent pacemaker (PPM) implantation are a known complication of TAVR. This study investigated the progression of cardiac conduction disease in the post-TAVR pacemaker population and identified predictors of post-TAVR right ventricular (RV) pacing dependence. METHODS: Prospectively collected echocardiographic, ECG, and PPM interrogation data of 262 consecutive patients who underwent TAVR with placement of a balloon-expandable valve at one institution from March 2012 to October 2016 were analyzed...

BACKGROUND: Congenital long QT syndrome (LQTS) can cause ventricular arrhythmic events with syncope and sudden death resulting from malignant torsades de pointes (TdP) followed by ventricular fibrillations (VFs). However, the syndrome is often overlooked prior to the development of arrhythmic events in patients with congenital heart diseases demonstrating right bundle branch block on electrocardiogram (ECG). We present a case of an adult patient with congenital heart disease who developed VFs postoperatively, potentially due to his mutation in a LQTS related gene, which was not identified on preoperative assessment due to incomplete evaluation of his family history...

REVIEW
Nikhil Mehta, Robert Vannozzi
Lithium has been used for the treatment of bipolar disorder for more than 6 decades. Reports of cardiac side effects resulting in both benign electrocardiographic (ECG) changes and near fatal arrhythmias have been reported in the literature. A systematic literature search was conducted on 2 electronic databases-PubMed and Medline-for the time period between January 1970 and March 2016 using the key word "lithium," along with "electrocardiography" or "ECG." All articles and their references were then screened by title for relevance by 2 authors and a librarian...

AIMS: Percutaneous septal reduction therapy by either alcohol or nonalcohol agents is an alternative approach to surgery in drug-refractory symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). Nonalcohol agents have some advantages and disadvantages over alcohol during the procedure. Nowadays, a novel non-alcohol agent, named as Ethylene-vinyl alcohol (EVOH) copolymer (Onyx® and Squid® ), is used during septal ablation. Thus, in this study, we aimed to evaluate both acute and long-term efficacy and safety profile of EVOH during septal ablation in HOCM...

Cardiac manifestations of subarachnoid haemorrhage (SAH) are well-documented phenomena that can complicate the treatment of this devastating condition. Here, we present a case of SAH presenting as complete heart block on initial assessment, an extremely rare event.A 53-year-old woman presented with a witnessed fall, sustaining a mild head injury. She denied any symptoms of SAH. Initial ECG revealed complete heart block, for which the patient was accepted under the cardiology team. For completion, a CT head scan was requested, this demonstrated significant SAH blood load in an aneurysmal rather than traumatic pattern...
