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 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.

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.

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.

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.

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.

ECG reveals clinical findings obscured by left ventricular hypertrophy

A man born with a congenital heart murmur developed systemic arterial hypertension as an adult. At age 50, he went to the hospital because of dyspnea. He also had a pulmonic valve ejection click and murmur of pulmonic stenosis. When at the hospital, his echocardiogram showed hypertrophy of both ventricles as well as an enlarged right atrium.
