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.

First Year Report Card: Inside the ICD National Registry

As the quest for more data in cardiac care grows with its link to reimbursement and quality of care measures, the number of national registries is sure to blossom. Last year, at the urging of the Centers for Medicare & Medicaid Services (CMS), the National ICD Registry was developed through a partnership of the American College of Cardiology Foundation (ACCF) and the Heart Rhythm Society (HRS).
