Overview area
Overview area In the Overview area, you can find the following information
about the exercise ECG:
Phase of the exercise ECG (monitoring, exercise,
recovery) and the duration of the phase.
Number and name of the Stage that is currently being
recorded
The current heart rate of the patient and the current
heart rate as a percentage of the maximum predicted
heart rate.
VES: the number of VES beats (Ventricular Extra
Systole) per minute.
The current blood pressure and previous blood
pressure are displayed.
The current workload and the current workload as a
percentage of the maximum workload. The maximum
workload is calculated based on the last valid stage. By
default the minimum stage duration is 30 seconds.
The RPM is displayed when an ergometer is used.
The protocol that you selected at the start of the test.
The following variables can be set:
Speed [mm/sec] and sensitivity [mm/mV].
Pacemaker on/off. ECG traces can contain artificial
pacemaker signal indicators. You can remove this
artificial pacer indicator by disabling the "Show Pacer"
selection. To learn how, see Exercise ECG settings-
General tab on page 48.
Baseline filter on/off. ECG traces can contain some
baseline wander caused by movement. You can reduce
this wander of the baseline by applying a baseline filter.
Muscle filter on/off. Muscle noise in an ECG signal
hides low amplitude signals that may be important for
the interpretation of an ECG. You can remove this noise
with a muscle noise filter.
After switching to the recovery phase, the total exercise time, the maximum heart rate, the
maximum workload, the protocol name, and the current METS values are displayed.
Tabs below the ECG traces:
Trends tab The Trends tab contains the event list and three curves:
Workload against time
Heart rate against time. The VES (ventricular extra
systole) count can be displayed in the Heart rate graph
from the shortcut menu.
Blood pressure against time. The RPP (Rate Pressure
Product) can be displayed in the Blood pressure graph
from the shortcut menu.
History tab The History tab shows the history of all twelve leads. Here, you
can move back in time, or print a view, while the exercise ECG
recording continues. Clicking the double arrow buttons moves
forward and backward from event to event.
