A device-implemented method is disclosed for early detection and monitoring of congestive heart failure in a patient. Ongoing measurements of impedance of a portion of the patient's body generally occupied by the lungs are performed by an implanted device, and, when the impedance measurements are determined by internal circuit components of the device to exceed a predetermined threshold value indicative of a need for immediate attention to a condition of congestive heart failure, a patient and/or physician alert is emitted by the device. An implant site at the left lower anterior lateral hemithorax is preferred.
