The present invention comprises a method and an apparatus for monitoring syncope, and having available for use an electrical cardiac output forcing (ECOF) back up. The present invention is an implantable device for recording the electrical activity within a human heart. The device of the present invention includes ECOF back up. 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. The electrodes are provided to electrically connect the power supply and the detection device to a patient's heart. A memory device is also provided which is connected to the detection device for recording electrical activity and/or blood pressure data of the patient's heart. In a preferred embodiment of the present invention, the memory device is 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 buffer 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 also provided which is connected to the detection device and to the power supply and to the electrodes. Upon the occurrence of a second predetermined event, such as fibrillation of the heart, the output control circuit causes the delivery of an electrical cardiac output forcing signal to the patient's heart. |
