PRIME ECG® System
PRIME ECG uses a series of pop-up windows providing instant access to more detailed diagnostic information without having to leave a particular display screen.
Figure 3: 80-lead Single-Beat Display with pop-up window.
In this example, a series of beats can be observed by placing a cursor over any beat (shown in the pop-up window as Channel Number 68). The ability to visualize a series of beats as well as to locate beat marks on the analysis beat is an important capability. The numbers correspond to those printed on the PRIME electrode vest.
The 80-lead single-beat image can be converted to a 3D torso view at the touch of a button.
Figure 4: Torso View of Posterior + RV MI.
The 3D torso can be rotated 360° to reveal areas of interest and to access views of underlying electrocardiographic detail by electrode site. Rotating from the posterior (shown) to the anterior surface allows the user to examine reciprocal values in order to confirm a suspected diagnosis.
The pop-up window reveals the trace at electrode 68, providing its numeric value at the “J-point.”

This value and tracing is accessed by placing a cursor over the desired electrode site.
The ST-0 Filter (Alarm) View is particularly useful to reveal at a glance only those areas where the recorded value may exceed pre-set diagnostic threshold limits.
Figure 6: ST0 Filter View.
The ST-0 (J-point) torso image has been rotated to view an area of orange-red centered in the lower right side of the patient’s back. The scale indicates the relative percentage above threshold that the underlying data reflects. The values of elevation or depression relate to specific regions of the heart.
A cursor placed on the suspect electrode creates a pop-up showing the underlying ECG trace.

With beat-markers visible, ST-elevation is clearly shown. This view can be particularly helpful to alert the physician to emerging or difficult to detect ischemia or infarction.
Each diagnostic image or map can be viewed in either 3 (torso) or 2 (flat) dimensions at the touch of a button.
Figure 8: Flat map image of posterior AMI with RV involvement.
The vector connects electrodes representing the recorded maxima and minima showing the highest and lowest values. This pattern would alert the physician to potential myocardial infarction in the posterior region. The migration of red color along the right side of the patient would indicate RV involvement – important information to guide proper treatment decisions.
The pop-up ECG is shown in the flat map view.

The user can examine these and surrounding electrode tracings by placing a cursor over the area of concern as shown above.
