ECG AC Line Filter - 50 Hz or 60 Hz.
ECG for Display - 0.15-40 Hz, 0.05-40 Hz
ECG for Printer - 0.05-150 Hz Diagnostic, 0.15-40 Hz, 0.05-40 Hz
Heart rate accuracy and response to irregular rhythm: Meets AAMI standard for ventricular bigeminy
(HR=80 bpm); slow alternating ventricular bigeminy (HR=60 bpm); rapid alternating ventricular
bigeminy (HR=120 bpm); bidirectional systoles (HR=90 bpm) as measured after a 20 sec stabilization
Heart rate averaging: For heart rates ≥ 50 bpm, heart rate is determined by averaging the 12 most recent
R-R intervals. Beats N, P, and V are included. When heart rate drops below 50 bpm, the four most recent
R-R intervals are used in the average. Note: For ventricular tachycardia alarms, which have a
user-definable PVC run length limit, the heart rate is based on the user-selected PVC length up to 9
Pace Pulse Detection Sensitivity: 1 mV for a width of 100 µs; 200 µV for a 500 µs width and 200 µV
for widths of 500 µs to 2 ms.
ECG Analog Output Bandwidth: 0.5 to 70 Hz
ECG Analog Output Gain: 1v output per 1mV input ±10%
ECG Analog Output Delay: Propagation delay time is <35ms from ECG input to ECG analog output.
Pacemaker Pulse Rejection Capability: Amplitude from ± 2 mV to ± 700 mV, width from 0.1 ms to 2.0
ms as per ANSI/AAMI EC 13:2002 22.214.171.124.
Pacer Pulse Detector rejection of Fast ECG Signals: Slew Rate of 1.1 V/s.
Heart Rate Response Time: 7 sec (80-120 bpm); 6 sec (80 to 40 bpm).
Time to Alarm for Tachycardia: 4 sec for 206 bpm (1 mV, halved amplitude and double amplitude) and
195 bpm (2 mV, halved amplitude and double amplitude) as measured following a normal 80 bpm rate
with upper alarm limit set at 100 and lower alarm limit set at 60 bpm.
Patient Isolation (Defibrillation Proof):
Lead ECG: Type CF
: Type CF
NBP: Type CF
Pads/Paddles: Type BF
Internal Paddles: Type CF
Other consideration: The HeartStart XL+ is suitable for use in the presence of electrosurgery. Burn
hazard protection is provided via a 1K current-limiting resistor contained in each ECG lead wire. Proper
lead placement (see "Electrode Placement" on page 45) is important to reduce burn hazards in the event
of a defect in the electrosurgical equipment.
