Smoking rates have dropped in recent years, but cigarettes remain the leading cause of preventable disease and death in the U.S., and electronic cigarettes pose a new danger, says Dr. Leslie Kohman, professor of surgery and director of outreach for the Upstate Cancer Center.

A new style of implantable defibrillator is providing options to patients at risk for sudden cardiac arrest. The device is sewn below a patient’s skin, leaving the heart and its vessels untouched. Electrodes continually analyze the heart’s rhythm and the device uses a pulse generator to deliver a shock if necessary.

Dr. Traian Anghel explains how this device improves upon previous defibrillators which had to be implanted in the heart.
