St. Jude Medical Inc., a medical device company, has launched Unify Quadra cardiac resynchronization therapy defibrillator (CRT-D) in India.

This helps physicians efficiently manage the changing pacing needs of patients with heart failure.

"Heart failure occurs when the heart is unable to pump enough blood to meet the body’s demands. It results in the build-up of fluids throughout the body, which can lead to shortness of breath, swelling, and heart rhythm abnormalities," the company said here in a statement on Tuesday.

The system helps the heart perform in its most natural state by synchronising the left and right ventricles of the heart through timed electrical pulses.

"The quadripolar system integrates multiple pacing configurations and features that provide physicians with more options to better manage common pacing complications without exposing the patient to additional surgeries in order to reposition the lead," it said.
