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.

Recall

Class I recall issued for 21 Medtronic CRT-Ds, ICDs

The FDA announced on Feb. 26 a Class I recall for nine of Medtronic's cardiac resynchronization therapy with defibrillation (CRT-D) devices and 12 of its implantable cardioverter-defibrillators (ICDs). Due to a manufacturing defect, a gas mixture can enter the devices and hamper their ability to provide shock therapy.

ICDs linked to more hospitalizations for patients with heart failure, CKD

For nearly 6,000 patients with heart failure and chronic kidney disease (CKD), the use of an implantable cardioverter defibrillator (ICD) showed no mortality benefit but a higher risk of subsequent hospitalizations after covariate adjustment, researchers reported in JAMA Internal Medicine.

Around the web

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."
