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.

Circulation: Implantable cardiac monitor can detect presence, absence of a-fib

Use of an implantable leadless cardiac monitor in patients can better detect and monitor atrial fibrillation (AF) due to an algorithm that can detect the presence or absence of the heart arrhythmia, a study published online in the Feb. 16 issue of Circulation: Arrhythmia and Electrophysiology found.

Radiologists to CMS: CTC reimbursement decision "misguided and shortsighted"

In an editorial in the February issue of the Journal of the American College of Radiology, two radiologists from the University of Arizona School of Medicine have called the decision of the Centers for Medicare and Medicaid Services not to reimburse CT colonography (CTC) misguided and shortsighted.

Three-dimensional sonography with a matrix array transducer is a reliable means of measuring renal volume during evaluations of patients with reduced renal function, according to a study in the February issue of the American Journal of Roentgenology.

JAMA: Paroxysmal AF shows better results with catheter ablation

The use of catheter ablation resulted in significantly better outcomes in patients with paroxysmal atrial fibrillation (AF) who had not responded previously to antiarrhythmic drug therapy, according to a randomized study in the Jan. 27 issue of Journal of the American Medical Association.
