Abstract
There is provided a system and method for increased data transmission from an implanted pacemaker when the pacemaker is in magnet mode. Pacemaker data including, e.g., pacemaker operating conditions, pacing events and patient events, is outputted by changing the asynchronous pacing rate to selected ones of available rates, and with a predetermined sequence, enabling read out of the data on an EKG strip chart. In a preferred embodiment, data-encoded pace pulses with intervals corresponding to selected rates are delivered in a predetermined sequence with fixed rate non-data intervals. For example, four pulses are delivered at 85 ppm followed by one or more data-encoded pulses, each data-encoded pulse being at 90, 95 or 100 ppm, whereafter the sequence is repeated with additional data-encoded intervals. The combination of rates for each of the data-encoded intervals represents the pacemaker data, and can be decoded by observing an EKG strip taken during the pattern of pace pulses. The invention provides for enhanced data transmission from an implanted pacemaker without the need of a programmer for receiving the data, and is thus particularly useful in environments where only a simple …
