MIAMI -- A device that automatically detects early symptoms of congestive heart failure has been implanted in patients in the United States for the first time.
The device is designed to allow patients to get treatment earlier and stay healthier.
When fluid levels around the heart get too high, they can interfere with a normal heartbeat and cause death.
One device was implanted in a patient at the University of Southern California last Friday. A second one implanted Monday in Antonio Comandari, 70, of Miami, monitors the amount of fluid in the chest. If there is a buildup, doctors can prescribe medication to reduce it.

The device costs about $30,000, lasts five to seven years, and should be available for widespread use by February, said Comandari's physician, Dr. Alberto Interian, chief cardiologist at Jackson Memorial Hospital.
It was approved by the Food and Drug Administration last month. About 400,000 Americans are candidates to receive the device, Interian said.
''More and more we're seeing patients who are living with severe congestive heart failure, where four or five years ago they'd be dead. Devices like this are improving the quality of life," he said.
Dr. Ann Bolger, a cardiologist with the American Heart Association, said the device could be helpful in catching problems quickly and helping people avoid hospitalization.
''The new part of this is basically implanting a remote sensor in the patient's body," Bolger said.
The device also works as a defibrillator to jump-start hearts and make them beat in a normal rhythm.
