The sensor indicated pacing rate is the sensor rate above
sensor’s threshold. The cumulative daily time when the sensor is
active is stored in the device for a period of 240 days. After 240
days, new daily values replace the oldest daily values.
2.11.7.2 Mean Heart Rate
The mean heart rate is calculated based on both ventricular
sensed and paced events. All types of events, including VES
(PVC) shall be included in the calculation of the mean value. On
a daily basis, the device measures and stores the patient’s mean
heart rate over a 24 hour period and has a value range of 0 to
180 bpm. The daily value is stored for a period of 240 days.
After 240 days, new daily values shall replace the oldest daily
values. The programmer presents the daily bpm-value in a trend
graph for the last 240 days.
2.11.7.3 Mean Heart Rate at Rest
On a daily basis, the Lumax CRT-D measures and stores the
patient’s resting heart rate (MHRR). Average values are
calculated over a defined period. The daily value is based on the
smallest mean value in any evaluation window over the resting
period. The mean heart rate is calculated based on both
ventricular sensed and paced events. All types of events,
including VES (PVC) shall be included in the calculation of the
mean value.
The MHRR value is measured during a programmed period,
defined by a Rest Period Start Time and a Rest Period Duration.
The resting period shall be adjustable via the programmer. The
MHRR has a value range of 0 to 180 bpm. The daily value
(MHRR) is stored for a period of 240 days. After 240 days, new
daily values replace the oldest daily values. The programmer
presents the daily bpm-value in a trend graph for the last 240
days.
2.11.7.4 Heart Rate Variability
Heart Rate Variability, which is the standard deviation of the 5-
minute mean normal to normal interval over the recorded time is
available in the statistics of the Lumax devices. This is based on
the atrial rate (P-P).
