Portable ANSiscope

The Portable ANSiscope is a safe and non-invasive monitoring device for the Autonomic Nervous System. It is battery operated, operates in real time and is ideal for operation in a physician's practice or in the field.

Measurement

• The initial ANSindex reading is displayed after 60 R-R intervals (approx 1 minute)
• Subsequent readings are taken with every heartbeat
• The display is updated with every heartbeat

Data acquisition

• Standard leads acquired: I, II, III, aVR, aVL, aVF, V1-6
• Lead and gain selection: User can dynamically select lead/gain during recording
• Digital sampling rate: 1666 samples/sec (0.6ms samples)
• Sampling resolution: 16 bit, bipolar
• Frequency response: 0.5 Hz to 40 Hz
• Filters
• High Pass: 0.5 Hz cutoff
• Low Pass: 40 Hz cutoff
• Notch filter: 50Hz, 60Hz for power interference
• Input dynamic range: 5 mV
• Common mode rejection: >100dB
• DC offset capability: 300 mV DC
• Input lead impedance: >20M ohm at DC

Patient information

• Input at the start of the measurement

Treatment notes

• Can be appended during the measurement

Help facility

• Is available at any time from the display

Data display

• Choice of colour or monochrome displays

ANS monitor

• The ECG signals are displayed in real-time on the LCD Screen of the Portable ANSiscope
• The display also shows
• ECG lead selection
• Heart rate
• The sympathovagal balANS (from –50 to +50)
• Both, sympathetic and parasympathetic ANSi indices (from –50 to +50)

Measurement of autonomic dysfunction

• The display shows
• The static balANS™
• The percentage of autonomic dysfunction
• The diabetic autonomic neuropathy (DAN/CAN) group
• • Healthy • Early • Late • Advanced • Most Advanced

Data storage capability

• USB memory keys (Thumb drives) can be used for data
• storage/backup
