This menu shows a 24-hour graph of minimum and maximum heart
rate for each individual minute. All ventricular and artifact
beats have been eliminated from the minute-by-minute analysis.
From this analysis, minutes of atrial fibrillation/flutter are
determined. A vertical marker can be moved to any specific 1-minute
location. The displayed 1-minute ECG verifies the existence or
non- existence of atrial fibrillation/flutter. Any minute can
be edited. An icon command allows all detected SVE beats to be
de-classified from the SVE beat count.

Atrial Fibrillation/Flutter Analysis

QT Validation
|
QT analysis is avoided in most Holter systems. However, elongation
of the QT interval can be the precursor to a mortality event.
The detection of abnormal QTc and QT intervals are important analysis
functions for a Holter ECG recording. This Holter system has the
most advanced QT validation program available.
QT is analyzed on a beat-to-beat basis. The heart rate is factored
into the QT analysis so that QTc and QT measurements are made
for the same data. A QTc histogram is then developed. Those QTc
measurements at the far right side of the histogram that exceed
a QTc of 450 ms are generally recognized as the worrisome QT intervals.

|
The mouse arrow is placed on a selected QTc interval, and its actual ECG
is displayed on the screen display. The "Ruler" function is
then activated to verify that the correct QT and QTc measurements were
made. If appropriate, the QTc histogram data can be rejected. When the
data is verified as being an abnormal QTc and QT event, the data is saved
and included in the QT report.
Each and every QTc and QT abnormality is easily and quickly validated.
|
After the mouse is clicked on a location on the QTc histogram,
the data is first displayed in the 16 per page ECG format. Vertical
markers are shown at both the beginning of the Q-wave and the
end of the T-wave. The purpose is to give the user a visual validation
that the QT analysis was performed for the correct QT interval.
For more detailed viewing, the large 8-second ECG is instantly
displayed. Vertical QT markers are also shown on this display
for further QT validation.

Heart Rate Variability
|
This displays shows the
Poincare and Lorenz plots across the top of the display. The left
side is a spectral power graph. The user can adjust the VLF, LF,
and HF ranges to whatever they believe is correct for their testing
purposes. The right side of the graph is a Time Domain R-R interval
graph. You can view the ECG data at either far end of the histogram
to determine if any of these ECG's should be rejected from the HRV
data file.

| |
|
| Each 5-minute data period
is analyzed by the spectral frequency methodology. A power graph
is drawn for each 5-minute period, and then overlayed over each
other. The resulting 3 D power graph creates a 24-hour power graph
that provides instant visual understanding of the patient's heart
rate variability.
This Holter system includes the unique feature of measuring the
drug efficacy in relation to HRV. The user simply enters the time
of taking the medication, and an immediate analysis shows the
reference spectral power compared to the first 30 minutes after
medication, and the first hour, and the first 2-hours, and the
first 4-hours, and the first 8-hours.

SAnalysis of each 5-Minute Period in the 3 D Power Graph
|
Spectral analysis of each
5-minute period is calculated. Power is calculated for Total Power,
VLF Power, LF Power, HF Power, and a formula for determining if
the period was sympathetic or parasympathetic in origin.

|
| The user can select all
or some of the report pages for the printed Holter ECG report. Each
page of the report can be shown in the "print preview"
mode.
If Full Disclosure was not printed during the initial analysis
mode, then full flexibility is provided for any selected Full
Disclosure print-outs.
This menu also allows report prints for Ambulatory Blood Pressure,
Event ECG, and Vectorcardiography reports.
Physician Comments can be enhanced by the physician. A library
of physician comments can be stored for quick insertion, whenever
desired by the physician.

PRIOR Program
|
This menu stores both the Holter Report
for each patient, and the 100% ECG file for each Holter recording.
Batch Printing of multiple Holter ECG reports is also accomplished
with this menu. The Holter recording file is automatically stored
into this program. If desired, the Holter ECG file can be deleted.
This menu also includes a Diagnosis "search" capability.
For example, the physician or technician may label each completed
Holter recording with various labels: such as; V-Tach, HRV, QT,
ST, etc. At a later date the physician may want to do some research
work on the QT patients. You would simply go to this Prior menu
and type in "QT" and click on the search icon. All of
the QT patient files, containing 100% of their Holter ECG recordings,
would be retrieved.
|
Exporting and Importing of PRIOR files with CD's:
The storage of Holter ECG Reports and 100% Holter recording files can
be stored on either the computer's hard disk or can be transferred onto
CD's. Standard Windows database searches allow for retrieval of archived
patient data.
| |
|
| This Holter system can be
entered into a multi-computer network, so that several different
computer work stations can have access to the review, editing, and
printing of the Holter ECG data. The resulting Holter ECG reports
can then be transferred by the internet to other interested parties.
Each computer work station in the network that wants to access
the main Holter acquisition computer must include its own Holter
security key. The remote computers in the network can view the
data, edit the data, and print the Holter ECG reports.
