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.

EU panel recommends approval of apixaban for AF patients

MR enterography provides diagnostic quality exam for kids w/ IBD

MR enterography offers a potentially attractive, radiation-free alternative to CT imaging of children with inflammatory bowel disease (IBD), Crohn's disease and chronic ulcerative colitis. The exam is feasible in patient nine years old and older, according to an assessment of its image quality, patient tolerance and performance published in the September issue of American Journal of Roentgenology.
