Electrophysiology & Arrhythmia


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.

Catheter ablation was associated with significantly fewer deaths and hospitalizations for worsening heart failure than medical therapy in a randomized trial of patients with atrial fibrillation (AFib) and heart failure.

A pair of researchers at Utah State University are aiming to revolutionize the world of digital monitoring with a new technology that can measure a person’s heartbeat using nothing more than a video camera and specialized software, the university announced Monday.

Atrial fibrillation (AFib) patients face higher odds for short-term cancer diagnoses but, depending on how long they've had AFib, the could face lower odds for cancer in the long run, a January study states.

Nearly half of all out-of-hospital cardiac arrest (OHCA) survivors struggle to rejoin the workforce and participate in society post-heart attack, a study published in Circulation: Cardiovascular Quality and Outcomes suggests.

Recent research provided sobering news on Americans’ ability to respond to cardiac arrest, which has about a 10 percent survival rate when occurring outside the hospital, according to the American Heart Association (AHA).

Study supports longer arrhythmia detection intervals for single-chamber ICDs

Patients with single-chamber (VVI) implantable cardioverter-defibrillators (ICDs) programmed with longer intervals for detecting arrhythmias experienced significant reductions in appropriate therapies, shocks and all-cause mortality when compared to patients with standardly programmed ICDs, according to a study published online Nov. 20 in JACC: Clinical Electrophysiology.

Athletes more likely to experience sudden cardiac arrest during racing, soccer, hockey

The incidence of young athletes experiencing sudden cardiac arrest during competitive sporting events is slim—just 0.76 cases in 100,000 athlete-years—but it does happen, according to one team of Canadian researchers who analyzed dozens of out-of-hospital cardiac arrests in an effort to dissect the underlying causes of these tragedies.
