Cardiac monitoring system and method
First Claim
1. A system for monitoring, analyzing, and/or diagnosing the cardiac activity of a patient, comprising:
- plurality of electrodes positioned at a respective plurality of locations on the patient for directing a respective plurality of electrical signals from the patient;
ECG data production means connected to the plurality of electrodes for acquiring said plurality of electrical signals directed by the plurality of electrodes and for producing ECG data in response to the acquired electrical signals;
display means connected to the ECG data production means for displaying a graphic depiction of at least part of the patient, the location, on the graphic depiction of at least part of the patient, of each of said plurality of electrodes, and a status of each of said electrical signals directed from said plurality of electrodes, wherein the status of each of said electrical signals directed from each of said plurality of electrodes includes at least one condition in which the electrical signal has a value such that the ECG production means is unable to produce a valid ECG signal in response thereto.

Abstract
A cardiac monitoring method and system provides advanced ischemia and infarction analysis and monitoring. Advanced calculations are performed on ECG signals to obtain parameter values relating to myocardial ischemia and infarction. Dominant heart beats are averaged to form a smooth beat, which is analyzed to determine the parameter values continuously and in real-time. The result of each analyzed time interval is presented as points in a trend graph on a monitoring display. All calculations are performed on-line and the trend curves are updated immediately. Systems and methods for monitoring, analyzing, and/or diagnosing cardiac activity that display a state of signals received from leads attached to a patient on a graphic depiction of the patient are also provided. The graphic depiction of the patient may include electrode position information.
