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.

Contraindication for blood thinners common in AFib patients, associated with high stroke risk

Roughly 12 percent of patients with medical claims for atrial fibrillation (AFib) are contraindicated for blood thinning treatment and remain at a high risk for stroke, a new study found.

An alternative to pacemakers? Ablation method treats sinus bradycardia

A new approach to treating symptomatic sinus bradycardia (SB) led to increased heart rate and improved quality of life in a single-center study of 62 patients, particularly those under the age of 50.

Gasping during cardiac arrest linked to improved survival, brain function

Gasping during cardiac arrest was associated with a nearly four-fold increase of one-year survival with favorable brain function, according to a study of 1,888 out-of-hospital cardiac arrests.

AFib patients with diabetes have higher risk of death—but not bleeding events

Diabetic patients with atrial fibrillation (AFib) have a lower quality of life and are at increased risk of death and hospitalization. However, they are no more likely than other AFib patients to have thromboembolic or bleeding events, despite a higher frequency of anticoagulation therapy, according to new research.

Low-risk patients opt for annual ECGs—despite clinical recommendations

Despite many physicians’ reticence to recommend annual electrocardiograms as part of a yearly physical, a study conducted in Canada proved that more than one in five annual health exams lead to one.

Ablation reverses LVSD in patients with persistent AFib

Catheter ablation (CA) is an effective way to restore sinus rhythm and reverse left ventricular systolic dysfunction (LVSD) in patients with persistent atrial fibrillation (AFib), according to new research.

Survival of cardiac arrest tied to neighborhood racial demographics

Cardiac arrest suffered in predominately black neighborhoods is associated with worse rates of survival and bystander treatment, despite quicker emergency medical services (EMS) response times, according to a new study in JAMA Cardiology.

Individual feedback key to reducing excessive ECGs

An educational intervention designed to reduce ordering of transthoracic echocardiograms (TTEs) informs physicians about their own test-ordering patterns and how their performance compares to their peers, according to recent research. Such knowledge can reduce inappropriate use of the tests.

Abbott releases software patch for pacemakers with cybersecurity vulnerability

Abbot Laboratories released a software update Aug. 23 for pacemaker and CRT-P devices. The Food & Drug Administration released a recommendation for patients to visit their healthcare providers to discuss vulnerability and updates.

Ablation tops drugs in treatment of AFib

Ablation led to greater quality of life improvements than drugs in patients with atrial fibrillation (AFib), according to results presented Aug. 29 at the European Society of Cardiology Congress.
