Abstract

The invention discloses a positioning diagnosis device for atrioventricular accessory pathway and atrial arrhythmia, which comprises a device for acquiring standard bipolar lead electrocardiosignals, a device for acquiring left atrial potential signals, a device for acquiring right atrial potential signals and a central control system shared by the three devices. The device for acquiring the standard bipolar lead electrocardiosignals comprises a standard bipolar lead electrode and a body surface electrocardio amplifier which are sequentially connected, the device for acquiring the left atrial potential signals comprises an esophagus electrode catheter and an esophagus bioelectric amplifier which are sequentially connected, the device for acquiring the right atrial potential signals comprises a thoracic surface right atrial potential detecting electrode and a thoracic surface bioelectric amplifier which are sequentially connected, and all the three amplifiers are connected with the central control system. The positioning diagnosis device is safe, rapid and effective, and can be used for making positioning diagnosis and distinguishing various complex atrial arrhythmia and atrioventricular accessory pathway.

Description

technical field [0001] The invention relates to a device for positioning and diagnosing cardiac atrioventricular bypass and atrial arrhythmia, in particular to a non-invasive positioning and diagnosing device for atrioventricular bypass and atrial arrhythmia. Background technique [0002] The atrioventricular bypass is an additional pathway between the atria and ventricles other than the atrioventricular node. During the maturing process of the heart, the cardiomyocytes between the atrium and the ventricle must be separated by biological insulating tissue except the atrioventricular node. If the separation is not complete, there will be additional muscle bundle conduction between the atrium and the ventricle, which will Formation of atrioventricular bypass. [0003] Atrioventricular accessory pathways include overt accessory pathways, recessive accessory pathways, and occult accessory pathways. Among them, 80% of the side channels have two-way transmission ability, 15% of ...
