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.

FDA announces recall after Philips heart monitor software failed to send alerts—multiple deaths reported

Philips is recalling the software associated with its Mobile Cardiac Outpatient Telemetry devices after certain high-risk ECG events were never routed to trained cardiology technicians as intended. The issue, which lasted for two years, has been linked to more than 100 injuries. 

HRS President Ken Ellenbogen, MD, FHRS, explains the need for the Heart Rhythm Advocates lobby group in Washington, D.C. to push for policies in Congress over reimbursements.

Why electrophysiologists needed a champion in Washington

Heart Rhythm Society President Kenneth A. Ellenbogen, MD, detailed a new advocacy group focused on improving EP reimbursements, patient care and access. “If you’re not at the table, you’re on the menu," he said.
