Sinus nodal reentrant tachycardia (wanda ake kira SNRT) yana daya daga cikin arrhythmias wanda aka rarraba a matsayin tachycardia supraventricular (SVT) , wanda yake da saurin zuciya arrhythmias wanda ya samo asali a cikin zuciyar zuciya. Sinus nodal reentrant tachycardia shi ne mafi girman nau'i na SVT.
Bayani
Sinus nodal reentrant tachycardia shine tachycardia mai reentrant . Kamar yadda yake kasancewa tare da tachycardias na reentrant, sinadarin tachocardia mai saukowa yana faruwa saboda akwai haɗin lantarki a cikin zuciya, wanda yake daga haihuwa.
A cikin sinadarin tachycardia na ainihin sinus, haɗin haɗuwa - da kuma dukkanin hanyar da ke tattare da arrhythmia - yana cikin ƙananan ƙwayar sinus .
Cutar cututtuka
Alamar cututtuka na SNRT sun kasance kama da alamun bayyanar da aka fi gani a kowane irin SVT. Mafi shahararren alama alama ce ta rashin amincewa , kodayake wasu mutane da wannan arrhythmia zasu fuskanci nauyin nauyin nauyin lantarki .
Kamar yadda mafi yawan SVTs, bayyanar cututtuka suna farawa ba tare da wani gargadi ba. Har ila yau, suna ɓacewa a hankali - sau da yawa bayan 'yan mintoci kaɗan zuwa sa'o'i da yawa.

Differences Daga Kalmomin da ba daidai ba ne Tachycardia
Samun sinadarai mara dacewa (TST) yayi kama da sinadarin tastal tachycardia tun lokacin da waɗannan arrhythmias sun fito daga kuskuren sinus.
Duk da haka, halaye su bambanta da yawa. Sinus nodal reentrant tachycardia ne tachycardia mai reentrant, don haka yana farawa kuma yana tsayawa takaici, kamar juyawa da kashe wani haske mai haske; kuma lokacin da mai haƙuri ba shi da ainihin labarin da tachycardia, zuciyarsa da zuciya ta kasance gaba ɗaya al'ada.
Ya bambanta, IST ne tachycardia ta atomatik . Saboda haka, ba ya farawa kuma ya dakatar da hanzari amma dai, ya ƙara yin hankali sosai kuma ya suma a hankali. Har ila yau, yawancin zuciya a mafi yawan mutane tare da IST sau da yawa ba daidai ba ne "al'ada." Maimakon haka, zuciya kusan kusan yana kasancewa a kalla kaɗan, koda kuwa idan ba ta samar da wata alama ba.
Jiyya
Idan lokuttan tachycardia ba saba da juna, kuma musamman idan ana iya samun sauƙi ta hanyar ƙarar ƙarar murya, mutane da sinadarin nodal rechyrant tachycardia bazai buƙatar kowane magani ba - ban da koyon yadda za'a gane cewa arrhythmia na faruwa, da kuma yadda don dakatar da shi.
