Abstract

A method for displaying time-correlated medical event data including the steps of: providing time-correlated event data to a display device; selecting a first event to be displayed; and displaying the first event together with a time-correlated second event on the display device. In another embodiment, the invention is a method for displaying time-correlated medical event data including the steps of: manually entering data comprising a first event into a display device; time-correlating the first event with data comprising a second event collected by a medical device; and displaying the first event together with the second event on the display device. In yet another embodiment, the invention is a method of creating a report showing the time correlation between recorded medical events, the method comprising the steps of: connecting a memory device to a display device, the memory device comprising a clock; retrieving event data and time data from a memory device; reading a memory device time from the memory device clock; and using the memory device time to associate time with the event data.

Claims

1. A method of assembling a database of time-correlated medical event data comprising the following steps:

gathering medical event data using an electrotherapy device, the medical event data comprising a plurality of data points corresponding to a first category of medical event and a plurality of data points corresponding to a second category of medical event;

correlating a data point from the plurality of data points corresponding to the first category of medical event with time;

correlating the plurality of data points corresponding to the second category of medical event with the plurality of data points corresponding to the first category of medical event; and

storing both pluralities of data points and their correlation information.

2. The method of claim 1 wherein the first category of medical event is patient ECG.

3. The method of claim 1 further comprising building a time-correlated event file from the pluralities of data points and their correlation information.

4. A method of using the database of claim 3 comprising displaying the pluralities of data points in a time-correlated manner.
