摘要
The present invention discloses a multifunctional portable electrocardiogram measuring device capable of correcting an input signal and a signal correction method. A multifunctional portable electrocardiogram measuring device according to the present invention comprises an electrode sensor, a pre-ASP and an ASP. The electrode sensor senses input signals from at least 3 leads attached to the body of a patient. The pre-ASP selects a path for a signal sensed by the electrode sensor, in response to a plurality of select control signals. The ASP eliminates noise included in the sensed signal from the pre-ASP and amplifies it. A signal correction method according to the present invention serves to correct an input signal (provided that the signal has an error) to a portable electrocardiogram measuring device, and to this end, the method comprises: determining an error in 3 leads and attached positions thereof by using input signals from at least 3 leads to an electrocardiogram measuring device; if no error is found, performing a subsequent process on the received signals; and if an error is found, changing a signal transmission path for the input signals from the at least 3 leads and then performing a subsequent process.
