Appl. No.:

11/693121

Inventors:

Dirk Q. Feild - Simi Valley CA, US
Richard E. Gregg - Westford MA, US

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 5/0402

US Classification:

600509

Abstract:

A physiological parameter analysis system () detects ECG electrode wire misplacement. The system () includes a transformation component () that transforms original ECG information and combinations thereof from a first ECG lead system to a second ECG lead system and an inverse transformation component () that derives ECG information in the first ECG lead system from the transformed ECG information and the combinations thereof. The system () further includes an analysis component () that determines a correct ECG lead configuration in the first ECG lead system from among the original ECG information and the combinations thereof based on the derived ECG information.

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 5/04

US Classification:

600509

Abstract:

A diagnostic ECG system analyzes lead traces for evidence of ST elevation in the lead signals. The pattern of ST elevation in leads having predetermined vantage points to the electrical activity of the heart and, in some instances, the presence of ST depression in certain other leads, identifies a specific coronary artery or branch as the culprit coronary artery for an acute ischemic event. The identity of the culprit coronary artery or branch is presented to the interventional cardiologist so that the correct coronary artery is accessed and the obstruction cleared. The technique can be used with standard 12-lead ECG systems as well as with ECG systems using fewer or more leads.

International Classification:

A61B 5/0402

US Classification:

600518

Abstract:

An atrial fibrillation (AF) monitor extracts two P wave features and an R-R interval feature from a sequence of ECG waveforms. The features are used by a classifier to classify a heart rhythm as AF or non-AF. The AF classification results may be further processed to reduce false alarm reporting. The AF classification results are used by an AF burden calculator to report AF burden in real time.

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - Eindhoven

International Classification:

A61B 5/0402

US Classification:

600509

Abstract:

A system and method for receiving a request for a test to be performed on a patient, retrieving information about the patient, receiving further information about the test after the test is performed and comparing the information to the further information. In addition, a system having an input device for receiving a request for a test to be performed on a patient and a management system configured to retrieve information corresponding to the patient, combine the received request and the retrieved information into a modified request, and forward the modified request to a device performing the test.

International Classification:

A61B 5/0452

US Classification:

600516

Abstract:

An ECG monitoring system continuously monitors a patient's ECG waveform and periodically identifies the patient's QT interval. QT interval values are averaged over time and a corrected interval value QTc and a change in QTc relative to a baseline, dQTc, are periodically produced. An alarm is responsive to updated QT interval values and issues an alarm whenever a selected QT value exceeds an alarm limit. The periodically produced QT interval values are stored and a trend display may be produced showing changes in the QT interval information over different periods of time. The trend display may selectively display the trend information either graphically or in tabular form.

International Classification:

A61B 5/044

US Classification:

600523

Abstract:

The segments of an anatomically corresponding bull's eye graph familiar to echocardiologists is annotated by coloring those segments for which ECG data indicates the presence of myocardial infarction injury. In an illustrated example, segments are colored with a second color when the ECG data corresponding to those segments are indicated as being the site of a coronary occlusion. The segments of the bull's eye graph may be colored in a third color with the results of a diagnostic imaging exam, such as by coloring segments exhibiting wall motion abnormalities with a third color.

US Classification:

600509

Abstract:

A diagnostic ECG system analyzes lead traces for evidence of ST elevation in the lead signals. The pattern of ST elevation in leads having predetermined vantage points to the electrical activity of the heart and, in some instances, the presence of ST depression in certain other leads, identifies a specific coronary artery or branch as the culprit coronary artery for an acute ischemic event. ECG measurements which are associated with the identity of specific arterial occlusion locations are calculated and used to form a classifier of the probability of occlusion at different locations. The location identified as having the highest probability is indicated to a user as the most likely occlusion location.

Abstract:

In various embodiments, a first classification assigned to a periodic component of an electrical waveform that represents electrical activity in a patient's heart may be identified. A corresponding periodic component of a hemodynamic waveform that represents hemodynamic activity in the patient's cardiovascular system may be analyzed. The corresponding periodic component may be causally related to the periodic component of the electrical waveform. Based on the analysis, the previously-assigned classification may be assigned to the corresponding periodic component of the hemodynamic waveform in response to a determination, based on the analyzing, that the previously-assigned classification also applies to the corresponding periodic component. In a database of hemodynamic templates, a hemodynamic template associated with the previously-assigned classification may be updated to include one or more features of the corresponding periodic component of the hemodynamic waveform.
