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 for recording and replaying electrotherapy event data comprising the following steps:

gathering electrotherapy event data using an electrotherapy device having a digital memory device attached thereto, the electrotherapy event data comprising patient ECG data and data for at least one other event;

correlating the electrotherapy event data with time;

storing time-correlated electrotherapy event data in the digital memory device;

detaching the digital memory device from the electrotherapy device;

attaching the digital memory device to a display device;

selecting an event to be displayed;

retrieving the time-correlated event data from the digital memory device; and

displaying the time-correlated event retrieved in the retrieving step on the display device.

2. The method of claim 1 further comprising the step of providing user-entered event data to the display device, the displaying step further comprising displaying the user-entered event data.

3. The method of claim 1 wherein the selecting step further comprises selecting an event from a list of events wherein the list comprises events gathered during the gathering step.
