title: Recording vectorcardiographic loops with a microdot thermal printer.
abstract: The principle of recording vectorcardiographic loops with a microdot thermal printer is developed using a very small memory area. It is based on two previous achievements: (i) orthogonal electocardiogram derivation from the conventional 12-lead system and (ii) recoding of biomedical signals with a microdot thermal printer, thus permitting the VCG to be just an extension of the standard ECG. The principle consists of decomposing the loop into horizontal sectors each one representing a non-ambigous function. It is implemented in ECG instruments, using the Gotemba microdot thermal printers TLP 480Z and TLP 880Z produced in Japan.
