An implantable apparatus for the detection and monitoring of spontaneous cardiac electrogram features in a comprises a cardiac monitoring device and a plurality of subcutaneous cardiac sensing electrodes electrically connected to the monitoring device. The sensing electrodes are configured for sensing cardiac electrogram features when implanted in spatially separate locations in a patient. A storage device contained within the monitoring device is operably associated with the subcutaneous electrodes and stores the cardiac electrogram features. Preferably, the plurality of subcutaneous electrodes are carried by a single elongate lead. A downloading device such as telemetry apparatus or transcutaneous electrical connectors may be provided so that the stored information can be downloaded to a separate apparatus external to the patient. In a preferred embodiment, the apparataus is a defibrillator. Methods of using such apparatus are also disclosed.

An image recording method as claimed in claim 1 wherein a resolution conversion is carried out as the conversion processing. 3. An image recording method as claimed in claim 1 wherein compression processing using coding is carried out as the conversion processing. 4. An image recording method as claimed in claim 1 wherein the re-recording is carried out by writing the data after the conversion over the original image data. 5. An image recording method as claimed in claim 1 wherein the re-recording is carried out by recording the data after the conversion in an area different from that of the original image data and erasing the original image data from the recording medium thereafter. 6. An image recording method as claimed in claim 1 wherein the accompanying information indicates whether re-recording of the image data is necessary or unnecessary. 7. An image recording method as claimed in claim 1 wherein the accompanying information indicates whether printing of the image data is necessary or unnecessary; and re-recording is judged to be unnecessary in the judgment if printing is necessary, while re-recording is judged to be necessary if printing is unnecessary. 8. An image recording method as claimed in claim 1 wherein the accompanying information is information showing the content of printing of the image data; and the judgment is carried out based on the content of printing. 9. The image re-recording method according to claim 1, wherein the accompanying information is inserted into the header of the image data. 10. An image re-recording apparatus comprising: photographed image recording means for recording data representing at least one image obtained by photographing in a recording medium; accompanying information recording means for storing accompanying information received with regard to the data of each image having been recorded, by relating the accompanying information to the image data, the accompanying information recording means capable of changing the stored information, as desired; re-recording necessity judging means for judging, based on the accompanying information, whether or not the data of each image are re-recorded as data having a smaller data size when a predetermined operation is carried out; data reading means for reading image data to be re-recorded from the recording medium, based on the judgment; data converting means for carrying out conversion processing such that the size of image data becomes smaller than the image data having been read; and re-recording means for collectively re-recording the image data after the conversion in the recording medium. 11. An image recording apparatus as claimed in claim 10 wherein the data converting means carries out a resolution conversion. 12. An image recording apparatus as claimed in claim 10 wherein the data converting means carries out compression using coding. 13. An image recording apparatus as claimed in any one of claim 10 wherein the re-recording means carries out the re-recording by writing the data after the conversion over the original image data. 14. An image recording apparatus as claimed in any one of claim 10 wherein the re-recording means carries out the re-recording by recording the data after the conversion in an area different from that of the original image data and erasing the original image data from the recording medium thereafter. 15. An image recording apparatus as claimed in claim 10, characterized by that the accompanying information indicates whether re-recording of the image data is necessary or unnecessary. 16. An image recording apparatus as claimed in claim 10, characterized by that the accompanying information indicates whether printing of the image data is necessary or unnecessary; and the re-recording necessity judging means judges that re-recording is unnecessary if printing is necessary or that
