Unnerving Sudden Cardiac Arrest

Patients with potentially fatal heart arrhythmias often benefit from receiving an implantable cardiac defibrillator (ICD) because of their high risk of sudden cardiac arrest.

The dilemma is figuring out who will benefit from the device.

Researchers suggest that positron emission tomography (PET) scan imaging may identify individuals at high risk of sudden cardiac arrest by detecting the loss of nerve function in the heart.
