A high intake of grapefruit juice—and other dietary flavonoids found in fruits, vegetables, tea and wine—could correspond to QT interval prolongation in healthy individuals and those with heart disease, leaving them vulnerable to serious arrhythmias like torsades-de-pointes.

A trio of studies presented at the Heart Rhythm Society’s 40th annual scientific sessions earlier this month highlight significant disparities in patient access to implantable cardiac devices—particularly in women and black patients.

The FDA is updating azithromycin drug labels to reflect evidence that the medication can contribute to a rare heart rhythm abnormality known as torsades de pointes.

The Heart Rhythm Society issued a first-ever consensus statement on the evaluation, risk stratification and management of arrhythmogenic cardiomyopathy at its annual conference in San Francisco this spring.

South Korean researchers are working on packing the ability to monitor heart health and detect signs of atrial fibrillation into what might be the smallest cardiology wearable to date: a “smart ring.”

BioCardia’s AVANCE steerable introducer family has received FDA 510(k) clearance, the company announced May 8.

Research presented at the Heart Rhythm Society’s 40th annual scientific sessions in San Francisco May 7 suggests heart patients with implanted electronic devices know less about their therapies than they think they do.

The FDA issued an alert May 7 warning patients with certain implanted Medtronic pacemakers or cardiac resynchronization therapy pacemakers (CRT-Ps) and their care teams to check for premature battery depletion in their devices after defects resulted in three reports and one patient death.
