Heart Rate Response to Irregular Rhythm: (AAMI EC13-2002, section 4.1.2.1.e.)
Ventricular Bigeminy: 80 BPM (expected)
Slow Alternating Ventricular Bigeminy: 60 BPM (expected)
Rapid Alternating Ventricular Bigeminy: 120 BPM (expected)
Bidirectional Systole: 45 BPM (expected)
Tachycardia Response Time:
Response time to tachycardia alarm is on average 3.4 seconds per AAMI EC-13-2002,
section 4.1.2.1.g, and IEC 60601-2-27:2011, subclause 201.7.9.2.9.101 b) 6). Response
times include a 1.0 second display update interval.
Pacemaker Pulse Rejection:
(In accordance with AAMI EC13:2002, section 4.1.4 and IEC 60601-2-27:2011, subclause
201.12.1.101.13)
• Pulses without overshoot: Rejects all pulses with amplitude of +2 mV to +700 mV and
duration of 0.1 ms to 2 ms, with no tail.
• Pulses with overshoot: Rejects all pulses with amplitude of +2 mV to +700 mV and duration
of 0.1 ms to 2 ms, with overshoot up to 100 ms.
• A-V sequential pulses: A-V sequential pacemaker pulses may not be rejected.
• Fast ECG signals: Approximately 50% of ECG input pulses with a slew rate of 3 V/s RTI
may trigger the pacemaker pulse detector.
Electrosurgery Protection: The X Series is suitable for use in the presence of electrosurgery
as specified in IEC 60601-2-27. Burn hazard protection via a 1K current limiting resistor
contained in each ECG leadwire.
