US Patent:

8560058, Oct 15, 2013

Filed:

Jan 9, 2009

Appl. No.:

12/811841

Inventors:

Saeed Babaeizadeh - Brookline MA, US
Richard E. Gregg - Westford MA, US
Eric Helfenbein - Sunnyvale CA, US
Sophia Huai Zhou - Camarillo CA, US

Assignee:

Koninklijke Philips N.V. - Eindhoven

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.

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.

Appl. No.:

13/643114

Inventors:

Richard E. Gregg - Westford MA, US
Sophia Huai Zhou - Briarcliff Manor NY, US

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - EINDHOVEN

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.

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - EINDHOVEN

International Classification:

A61B 5/02
A61B 5/04
A61B 5/0468

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.

International Classification:

A61B 5/00
A61B 5/0215

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.

Abstract:

Various embodiments of the present disclosure encompass an ECG control network of ECG test controller () and ECG context controller (). The ECG test controller () control a recording of an ECG test. The ECG context controller () control a synchronization of the recording of the ECG test by the ECG test controller () with a recording of a video clip illustrative of a clinical context of the ECG test and/or a recording of an audio clip informative of a clinical context of the ECG test. The ECG context controller () further control a simultaneous presentation of a display of the recording of the ECG test with of a playing of the video clip contextually interpretative of the ECG test and/or a playing of the audio clip contextually interpretative of the ECG test.

International Classification:

A61B 5/24
A61B 5/00

Abstract:

A system and method for modeling and visualizing ST segment morphology in an ECG. Many cardiac conditions show ST-elevation in ECG data and may be misdiagnosed as a consequence. The exemplary embodiments model a segment in the ECG with a curve and extract features from the curve to discriminate between the cardiac conditions, including STEMI.
