Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Boston Scientific announces pacemaker CE mark with options for magnetic resonance imaging

Boston Scientific Corporation has received CE Mark approval for the ACCOLADETM pacemaker family. When implanted with the company's INGEVITYTM leads, ACCOLADE pacemakers are the first to enable patients to receive full-body MRI scans in both 1.5 Tesla and 3.0 Tesla systems. In addition, the Boston Scientific ImageReadyTM technology offers the most flexible MRI options, allowing higher energy scan sequences, and featuring a programmable MRI timer designed to improve patient workflow.

A new investigational cardiac pacemaker as small as a vitamin

Cardiologists on the medical staff at Baylor Jack and Jane Hamilton Heart and Vascular Hospital (BHVH) today implanted an investigational cardiac pacemaker the size of a multivitamin. The first implantable pacemakers, developed in the late-1950s, were nearer the size of a transistor radio.

Imricor Medical Systems announces first procedures in clinical study of MR-enabled cardiac ablation products

Imricor Medical Systems, Inc. announced the first three cardiac ablation procedures were completed in the first clinical study that is evaluating the feasibility of their MR-enabled products to treat atrial flutter. Professor Reza Razavi, Head of the Division of Imaging Sciences & Biomedical Engineering, King's College London, is the principal investigator for the study and along with Mark O'Neill, Professor of Cardiac Electrophysiology and Consultant Cardiologist, Guy's and St. Thomas' NHS Trust performed the procedures. The prospective pilot study will enroll up to 15 patients at this center.

ESC Hot Line: Data reports NVAF patients taking Pradaxa (dabigatran etexilate mesylate) experienced slower decline in kidney function compared to those on warfarin

Boehringer Ingelheim Pharmaceuticals, Inc. today announced results from a new post-hoc sub-analysis of the pivotal phase III RE-LY trial assessing renal function change in patients with non-valvular atrial fibrillation (NVAF) treated with Pradaxa (dabigatran etexilate mesylate) compared to warfarin. The findings suggest that patients treated with PRADAXA experienced a slower decline in kidney function compared to those being treated with warfarin, with the slower decline most marked in patients treated with PRADAXA who had mild kidney impairment at the start of the RE-LY trial. The results were presented today during the European Society of Cardiology (ESC) Congress 2014.

Global survey of cardiologists highlights complexity of managing non-valvular atrial fibrillation and reinforces need for individualized approach to patient care

Daiichi Sankyo and the Heart Rhythm Society today announced results from a global survey, which polled cardiologists from around the world and revealed that a majority (58%) of cardiologists agree that there is no such thing as a “typical” non-valvular atrial fibrillation (NVAF) patient.

Subgroup analysis of ENGAGE AF-TIMI 48 explores the relationship between edoxaban dose, concentration, anti-Factor Xa activity and outcomes

Daiichi Sankyo Company, Limited today announced data from a subgroup analysis of the phase 3 ENGAGE AF-TIMI 48 study, that explores the relationship between edoxaban dose, concentration and anti-factor Xa activity in patients with non-valvular atrial fibrillation (NVAF). The analysis also compared rates of major bleeding and efficacy outcomes [stroke and systemic embolic events (SEE)] of edoxaban versus warfarin, stratified by dose reduction status.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
