Ukuxilongwa kwe-tachycardia kungenziwa kusuka ku- izimpawu eyethulwa ngumuntu obonisana naye noma otholwe udokotela ekuhlolweni noma ku-electrocardiogram.

Kungase futhi kube yisimo esiphuthumayo esidlulele lapho umuntu equleka.

Ngemva kokuhlolwa komtholampilo, udokotela wenza noma uyala ukuhlolwa okuhlukahlukene.

Okokuqala a i-electrocardiogram (ECG), umkhondo wayo okhombisa ukusebenza kukagesi kwenhliziyo. Ngenxa yezinzwa ezibekwe ezingxenyeni ezihlukene zomzimba (isifuba, isihlakala, amaqakala, njll.), udokotela angakwazi ukubona ngeso lengqondo izimpawu zikagesi zalesi sitho futhi abone okungavamile.

Idivayisi ephathekayo, i holter, ivumela ukuqapha kwesilinganiso senhliziyo samahora angu-24. Ngakho-ke, i-tachycardia eyenzeka kuphela ngaphansi kwezimo ezithile ingatholwa. Okunye ukuhlolwa, njenge-ultrasound yenhliziyo (bhequza) isetshenziselwa ukubona ngeso lengqondo ukugeleza kwegazi nokuthola amahlule athile. Ukuhlolwa kokuzivocavoca (ECG okwenziwe ngesikhathi sokuhlolwa kokuzivocavoca njengokuhamba ngebhayisikili) kungase futhi kunqunywe ukuze uqonde kangcono uhlobo lwe-tachycardia ehilelekile.
