Ukuhlolwa Kokucindezeleka Kwe-Adenosine ukuze ufunde ngokugeleza kwegazi enhliziyweni! Ungesabi, ake sixoxe.

Ungase uzibuze ukuthi iyini i-Adenosine Stress Test. Mhlawumbe udokotela ukucele nokuthi wenze lokhu kuhlolwa. Nokho, ungakhathazeki! Kulula kakhulu. Namuhla sizoxoxa ngalokhu kuhlolwa, ukuthi kwenzani, kwenziwa kanjani, nakho konke okudingeka ukwazi. Kalula nje, kuwukuhlolwa okulinganisa ukuthi inhliziyo yakho ithola igazi kangakanani.

Kungani kwenziwa lokhu kuhlolwa kokucindezeleka kwe-adenosine?

Cabanga nje, uma usebenza, njengalapho uzivocavoca, inhliziyo yakho idinga igazi eliningi kunalapho uphumule. Ngalesi sivivinyo sokucindezeleka se-adenosine, odokotela bahlola ukuthi inhliziyo yakho ithola igazi elanele yini phakathi nesikhathi sokusebenza kanye nesikhathi sokuphumula. Ngenxa yalokhu, inani elincane lomuthi obizwa ngokuthi i-adenosine liyajovwa. Ngemuva kwalokho, imithambo yegazi (imithambo yegazi) enhliziyweni yakho iziphatha ngendlela efanayo lapho uzivocavoca.

Lolu vivinyo lusiza udokotela ukuthola ukuthi:

• Ingabe kukhona ukulimala okungapheli emisipheni yenhliziyo yakho?
• Ingabe igazi nomoya-mpilo owanele ugeleza enhliziyweni?
• Ingabe unesifo semithambo yenhliziyo (CAD) ? Yilapho ukunikezwa kwegazi emisipheni yenhliziyo kuncipha khona.

Ubani ovame ukwenza lokhu kuhlolwa?

Akuwona wonke umuntu ozodinga lokhu kuhlolwa. Udokotela angase akucele ukuthi wenze ukuhlolwa kokucindezeleka kwe-adenosine ngezizathu ezilandelayo:

• Uma ungakwazi ukwenza izivivinyo ezidingekayo ukuze uhlolwe njalo ngokucindezeleka, njengokuhamba nge-treadmill.
• Uma ungakwazi ukuphakamisa izinga lokushaya kwenhliziyo yakho ngokwanele naphezu kokuzivocavoca umzimba.
• Uma uthatha imithi ethile, njenge-beta-blockers .
• Uma ufakwe i-ventricular pacemaker .
• Uma unesifo esibizwa ngokuthi i-left bundle branch block .

Ukuhlolwa kokucindezeleka kwe-adenosine kusebenza kanjani?

Kulula kakhulu. Esivivinyweni sokucindezeleka se-adenosine, udokotela ukunika inani elincane lomuthi i-adenosine.
