Table 10. Rate related patterns
The analysis program does not automatically:
• Detect Atrial Fibrillation and Flutter. View Pause Review, Supraventricular Review,
Rate Graphs Review, and Full Disclosure as an aid to identify these types of
Arrhythmia patterns.
• Detect Ventricular Fibrillation and Flutter. View Arrhythmia Review and Full
Disclosure as an aid to identify these types of Arrhythmia patterns.
• Detect and classify any Intraventricular conduction defects. View Forms Review,
Arrhythmia Review, and Full Disclosure as an aid to identify these types of Ventricular
conduction defects.
• Measure P-R interval or produce any automatic classifications of any
Atrio-Ventricular (AV) blocks. View Pause Review, Supraventricular Review, Rate
Graphs Review and Full Disclosure as an aid to identify these types of AV conduction
defects.
• Identify Paced beat. A green pacer mark is provided by the program to identify the
presence of a pacer firing detected within the recorder. The clinician may reclassify
beat or forms as Paced.
Strip Determination
The analysis program selects automatic strip examples based on the following categories:
• Ventricular Isolated (2)
• Ventricular Couplets (2)
• Ventricular Runs - selected based on longest run (4)
• Supraventricular Isolated (2)
• Supraventricular Couplets (2)
• Supraventricular Runs - selected based on longest run (4)
• Pauses - selected based on longest pause (4)
• Tachy - selected based on highest Tachycardia Rate (2)
• Brady - selected based on slowest Bradycardia Rate (2)
• Max. Heart Rate - selected on maximum Heart Rate (1)
• Min Heart Rate - selected on minimum Heart Rate (1)
• ST Elevation per channel - selected on maximum average ST Elevation found
(2 per channel)
Event Definition
Tachy Episodes 15 seconds or more of heart rate that exceeds the Tachy Threshold (user configurable)
Brady Episodes 15 seconds or more of heart rate that exceeds the Brady Threshold (user configurable)
Pauses any valid R-R interval that exceeds the Pause Threshold (user configurable)
Min HR time of minimum heart rate reported for entire procedure
Max. HR time of maximum heart rate reported for entire procedure
Min R-R beat with the shortest R-R coupling interval reported for entire procedure
Max R-R beat with the longest R-R coupling interval reported for the entire procedure
