Compact wireless ECG registration
The Lode ECG streamer has 4 leadwires that will deliver 2 channels of ECG: Lead I and Lead II. The streamer can be supplied with an ECG trigger acquisition set for triggering the TTL pulse (needed for blood pressure measurement).
The ECG streamer is extremely lightweight and small. The batteries are rechargeable and can be used for approximately 8 hours. During a cardiac rehab training, test subjects can press the marker button themselves. The streamer is supplied with disposable electrodes to create more flexibility when moving from one exercise device to the other.

Frequently asked questions
Is Lode recommending special disinfection procedures for the Lode products due to COVID-19?
Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!
Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.
Will my existing Lode streamers and ergometers still be compatible when I upgrade the LCRM software to a newer version?
Yes you can upgrade to a newer LCRM version without any influence on the total LCRM installation, The Lode Streamers, ergometers and treadmills will work as usual.
How do I switch on the ECG streamer?
A press longer than 3 seconds of the blue start/stop button starts the measuring of the device. A green light indicates that the device is switched on with a slow blink. A blue light indicates the connection state. A fast blink of the blue light indicates the device
is waiting for a connection. A slow blink of the blue light indicates the device is connected and sending data.
How do I switch off the ECG streamer?
To switch the ECG streamer OFF, press and hold the blue button for about 3 seconds. The green light will blink 3 times and the product is OFF.
How do I recharge the battery of the ECG streamer?
Besides charging the device with the USB charge cable (950792), there is a docking station (950840, optional) to charge four streamers at the same time. The red light indicates the state of the battery charging. This light is on during charging and off when charging finished.
How should I place the electrodes to obtain a proper Lead I and lead II ECG signal?
Placement of the electrodes: Red: right arm, 1st intercostal space, avoiding thick muscle Yellow: left arm, 1st intercostal space, avoiding thick muscle Green: left leg, 6th intercostal space Black: right leg ground electrode, 6th intercostal space Lead I: Red Electrode (right arm) and Yellow Electrode (left arm) Lead II: Red Electrode (right arm) and Green Electrode (left leg) See manual m950920 chapter 7 for a picture of the electrode placement.
Do I need special ECG electrodes for a cardiac rehab training?
It’s essential to use ECG electrodes which are suitable for stress testing. These electrodes have extra-strong adhesion and therefore stick better during exercise and/or testing. Use always 4 electrodes of the same brand, type and expiration date. The cheaper quality ECG electrodes for taking an ECG during rest will not stick enough when the patient starts to sweat.
Is it possible to lower the workload in case of a sudden SpO2 drop?
SpO2 can be used to control the load of the ergometer. In the tab “SpO2 ” you can choose to use SpO2 for automatic load adjustment and you can edit the settings (see manual LCRM 950902)
Is it possible to use non-Lode devices in LCRM?
LCRM is not compatible with bicycle ergometers and treadmills of another brand, the workload, speed or slope can not be crontrolled. It is possible however to select the “ECG-only protocol” and use the non-Lode device as a stand-alone system.
Is LCRM compatible with automatic BP measurement devices?
When the automatic Blood Pressure option is available on the Lode ergometer, this module is compatible with LCRM. You can program the blood pressure interval in the exercise protocols.
Is it possible to use a Heart rate controlled protocol in LCRM?
The stage “Heart Rate Controlled” gives you the opportunity to create a protocol to train with a certain heart rate. You can set the training duration and the target heart rate. The intensity (load or speed and inclination) will be controlled by the software in order to come to this certain heart rate as well as to keep the heart rate stable around the target. To set “The Target Heart Rate” you can choose between absolute heart rate, relative to max heart rate or Karvonen.
At what distance can the wireless ECG connection still function?
The theoretical maximum range of the signal is 20 meter (depending strongly on the environment)
Is it possible to receive an interpretation of the ECG (like ST changes, rythm disorders, fibrilations) with LCRM?
The LCRM software is not meant to be a diagnostic tool, the ECG signal can be used for monitoring. When there are concerns about the data, always use a diagnostic 12-lead ECG device to (dis)confirm
What do I need to do when I receive the message: poor bluetooth signal?
The message “poor bluetooth signal” is not a warning about the quality of the ECG signal. It’s only a warning about the bluetooth signal. The ECG streamer might be near the maximum range of the bluetooth (theoretical maximum 20 meter). Bluetooth signals can be disturbed by external causes as well (like other BT devices in or near the streamers)
Is it possible to use the LCRM and streamer for a maximal exercise test?
The LCRM software is not meant to be a diagnostic tool, the ECG signal can be used for monitoring up to 16 patients simultaneously. For a maximal (CPET) exercise test, always use a diagnostic (12-lead) exercise ECG device.
Is it possible to use the LCRM software and streamer in a ball game?
When there is no ergometer connected to the slot, you can create “ECG Only” Protocols. These protocols are meant to monitor ECG while the participant is doing exercises without ergometer, like ball games, squats, lunges or jumps. Keep in mind the streamer needs to be in the range of the system and extreme muscle activity of the upper body will influence the ECG quality.
My streamer does not switch on, what should I do?
Place the streamer in a docking station or connect it with a charge cable to a PC or a USB charger for at least 2 hours.
My Streamer does not connect to the PC?
Check if the USB dongles are connected to the PC and if there is at least one more dongle connected to the PC than the amount of streamers you have.
Do I need a new license for the upgrade to a newer version of LCRM?
Yes you will need a new license to upgrade LCRM. This license can be supplied by the Lode service support. You may need to order this via your distributor
Why should I consider replacing my ECG modules for Lode ECG Streamers?
The Lode ECG streamer is a compact 2-channel system with integrated rechargeable batteries. It can be supplied with an optional custom pack (#950824) for triggering the TTL pulse (needed for blood pressure measurement).
Can I use a charged ECG streamer for a whole day?
Fully charged the streamer can be used for approximately 8 hours. The integrated battery of the ECG streamer can be recharged with the USB charge cable (950792), or 4 simultaneously in the optional docking station (950840).
