BIOMONITOR IV Technical Manual Chapter 6: Diagnostics 6.1 Diagnostics Overview BIOMONITOR IV can store a variety of statistical information. The various statistics consist of such features as rate histograms, rate trends, and activity trends, which are described in the following sections.
Heart rate information is based on the daily average heart rate and is displayed as a single data point for the day. BIOMONITOR IV collects resting heart rate values in 10-minute blocks of time during the mean heart rate at rest recording time. The lowest average collected over the recording period is used as the statistical point for that given day.
Chapter 6 BIOMONITOR IV Technical Manual 6.3.3 Activity Trend The Activity trend, shown in Figure 39, displays the daily percentage of activity as detected by the motion sensor of the device. Figure 41: Activity trend 6.4 AF Details 6.4.1 AF Trends The AF trends diagnostic provides information related to the number and duration in hours of AF events on a daily basis.
Chapter 6 BIOMONITOR IV Technical Manual 6.4.2 AF Time of Occurrence The time of occurrence, shown in Figure 41, summarizes the times of day that atrial tachyarrhythmia episodes began and is broken into three-hour time blocks. Knowing the time of day when atrial tachyarrhythmias begin may help determine whether a particular event will precipitate the tachyarrhythmia.
Chapter 6 BIOMONITOR IV Technical Manual 6.4.4 Ventricular Rate During AF The ventricular rate during AF graph provides the mean and the maximum heart rate during AF. Large differences in the mean and maximum rates may indicate an irregular ventricular response during the AF while small differences may imply that ventricular rate is more stable during AF.
The noise duration trend provides the amount of noise sensed daily by the device, expressed as a percentage of time per day by the BIOMONITOR IV. A high percentage of noise events could interfere with the BIOMONITOR IV’s ability to detect arrhythmias.
Home Monitoring can be used to provide the physician with reports from the BIOMONITOR IV and can process them into graphical and tabular format called a Home Monitoring Report. This information helps the physician optimize the diagnostic process, as it allows the patient to be scheduled for additional clinical appointments between regular follow-up visits if necessary.
