Overview
The Memtec model 950-12LR-HHC is a battery operated ECG monitoring device
that provides true 12-lead, high-resolution, clinical/research-grade recordings
with wireless transmission in the 2.4Ghz ISM band for ECG machine function.
The device has a resolution of 12 bits, with data viewed and stored
uncompressed on a PC. The data is transmitted wirelessly to a PC in real-time
for use as an ECG machine. Data integrity is provided through a unique patent-
pending technique that includes data, time and patient ID stamps along with a
CRC-16 check on the recording every 2 minutes, ensuring usable recordings
while preventing patient data mix-ups. A large LCD provides real-time patient
ECG signals to confirm lead placement during patient hook-up. One “AA”
alkaline battery provides power for up to a month of use.
The model 950-12LR-HHC over-samples the input signal at a rate of 6,000
samples/second to support hardware pacemaker detection on all channels.

Patient Hookup
Once the cardiologist has specified the desired type of patient hookup, the
specific location and method of attachment of the electrodes to the body is
crucial to achieving the best signal. The following recommendations enable the
user to obtain the highest quality signals and recording:
1. Connect the electrodes to the bony area over a rib or sternum to reduce

crucial to achieving the best signal. The following recommendations enable the
user to obtain the highest quality signals and recording:
1. Connect the electrodes to the bony area over a rib or sternum to reduce
muscle noise interference. Placing the electrode over large muscle areas or
in the intercostal spaces can cause high frequency artifacts that degrade the
