Provocation of obsessive thoughts induces physiological brain changes in 64-year-old man with OCD

Thoughts that lead to compulsive behavior in obsessive-compulsive disorder (OCD) correspond with physiological changes in the brain, according to a new case study. The article is published ahead of print in the Journal of Neurophysiology.

New algorithm guides catheters to accurately locate atrial fibrillation sources

Patients with atrial fibrillation or AFib experience chaotic electrical signals in the upper chamber of their heart (atria), which cause an irregular or quivering heartbeat (arrhythmia) that can lead to blood clots and heart failure. AFib also is a major cause of stroke and affects 33 million people worldwide.

New therapy to re-engage the heart's natural electrical pathways offers more treatment options

A new therapy to re-engage the heart's natural electrical pathways - instead of bypassing them - could mean more treatment options for heart failure patients who also suffer from electrical disturbances, such as arrhythmias, according to research led by the University of Chicago Medicine.

Bariatric surgery before AF ablation reduces arrhythmia recurrence risk

A new study shows that overweight patients who have bariatric surgery before undergoing ablation reduce their risk of the arrhythmia returning.

Survey reports large discrepancy in patient’s knowledge of cardiac implantable electronic devices

Results from a new survey are the first to report a large discrepancy in patient’s knowledge of their cardiac implantable electronic device.

Study confirms QT-prolonging effects of grapefruit juice

Grapefruit juice is already listed as a substance to avoid when taking QT-prolonging medications because it increases the toxicity of many drugs.

Michigan State University receives $1.8 million NIH grant to improve brain implants

Michigan State University has landed a $1.8 million National Institutes for Health R01 grant to improve brain implants - "electroceuticals" used to treat Alzheimer's, Parkinson's, depression and traumatic injuries.

Fetal exposure to nicotine linked with SIDS and cardiac arrhythmias in newborns

Fetal exposure to tobacco smoke in utero is associated with sudden infant death syndrome (SIDS) and cardiac arrhythmias in newborns. In a novel study in rabbits, investigators provide the first evidence linking fetal exposure to nicotine to long-term alterations of the cardiac sodium current.

New computer program predicts risk of life-threatening arrhythmias

Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers from Johns Hopkins has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit--or not--from lifesaving implanted defibrillators.

Study explores how a hallucinogenic drug impacts the brains of mice

While there is increasing interest in using hallucinogenic drugs to treat conditions like depression and post-traumatic stress disorder, scientists are just beginning to understand what these drugs actually do in the brain—and how they cause hallucinations.

New study examines smarter automatic defibrillator

Thousands of patients with congestive heart failure benefit from automatic implantable cardiac defibrillators that deliver shocks to the heart to correct abnormal heart rhythms. These defibrillators improve survival in patients who are at risk for sudden cardiac death.

Remote monitoring of implanted defibrillators in heart failure patients prevents hospitalizations

Remote monitoring keeps heart failure patients out of hospital, according to late-breaking findings from the RESULT trial presented today at EHRA 2019, a European Society of Cardiology congress. The set-up is so effective that it has won reimbursement from the national health system.
