Abstract
A method and apparatus for monitoring syncope, and having available for use an electrical cardiac output forcing (ECOF) back up. An implantable device, including an ECOF back up, for recording the electrical activity within a human heart is provided. The device includes a power supply for operating the device and for providing the necessary output forcing signals. A monitoring or detection device is provided connected to the power supply. Electrodes are provided to electrically connect the power supply and the detection device to a patient's heart. A memory device is also provided connected to the detection device for recording electrical activity and/or blood pressure data of the patient's heart. The memory device may be comprised of a short term loop buffer for continuously recording the electrical data from the patient's heart and a long term storage buffer. The short term loop may be of a desired size, for example, capable of storing from 1-30 minutes of data before overriding occurs. Upon the occurrence of a predetermined event, for example, a bout of syncope, the data in the short term loop buffer is transferred to the long term storage buffer. An output control circuit is al…
