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.

Philips updates EP physiomonitor at HRS

Philips Healthcare introduced a new electrophysiology (EP) logging and reporting feature for its Xper Information Management Physiomonitoring 5 product at the 2009 Heart Rhythm Society (HRS) conference in Boston last week.

HRS: ICDs extend the lives of heart attack survivors by one year

BOSTON--In heart attack survivors who received implanted cardioverter defibrillators (ICDs), mortality benefit was sustained over eight years of follow up, according to the results of late-breaking clinical trial presented May 14 at the 30th annual scientific sessions of the Heart Rhythm Society (HRS).

HRS: Multaq linked with less death, hospitalization in heart failure patients

Dronedarone had no adverse effect on mortality in atrial fibrillation (AF) patients with congestive heart failure (CHF) and/or a left ventricular ejection fraction less than 0.35; and patients had a lower incidence of primary outcome events when allocated to dronedarone therapy, according to the ATHENA late-breaking clinical trial presented May 15 at the 30th annual meeting of the Heart Rhythm Society (HRS) in Boston.

FEATURE: Laser lead extraction can be safe, effectivewith experienced operators

BOSTONLaser-assisted lead removal demonstrated safety and efficacy, based on initial data from the four-year, retrospective LExICon study presented today at the 30th annual scientific sessions of the Heart Rhythm Society (HRS). However, principal investigator Bruce Wilkoff told Cardiovascular Business News that the greatest differentiator in success rates and patient outcomes depends on operator experience.

HRS lead performance guidance focuses on malfunctions

The Heart Rhythm Society (HRS) released the first comprehensive guidance document on lead performance in pacemakers and implantable cardioverter defibrillators (ICDs), recognizing that lead malfunction is crucial to patient safety, and asserting that physicians and patients must have timely and accurate data when malfunctions occur. The document was released Wednesday at the 30th annual HRS scientific sessions in Boston.

Sebelius staffs new healthcare reform office

Secretary of Health and Human Services (HHS) Kathleen Sebelius has appointed personnel for the newly created Office of Health Reform, which will spearhead the department's efforts to pass health reform this year and coordinate closely with the White House Office of Health Reform.

Consensus: More trials needed on catheter ablation of ventricular arrhythmias

BOSTON--A call to action for more research into catheter ablation in the field of ventricular arrhythmia (VA) has been released in a joint consensus document from the European Heart Rhythm Association (EHRA) and the Heart Rhythm Society (HRS) issued today at the 30th annual scientific sessions of the HRS held in Boston.

JACC: One in 1,000 a-fib patients risk death from catheter ablation

Death that results from catheter ablation of atrial fibrillation occurs in one in1,000 patients, according to a study in the May 12 issue of the Journal of the American College of Cardiology.
