I-paroxysmal supraventricular (supranventicular) tachycardia ibonakala ekukhuphukeni kwentengo yenhliziyo kuya ku-140-240 ukushaya ngomzuzu ngenkathi igcina isigqi sokushaya kwenhliziyo. Lokhu kuhlasela kwenzeka ngenxa yokuphambaniswa okuphindaphindiwe emnyangweni wezinhliziyo ezingenhla kanye nokusakazwa kwendilinga ye-excitation ngokusebenzisa i-myocardium, futhi ukugcina kusuka kwesikhashana kuya ezinsukwini ezimbalwa.
Ukuxilongwa kwesifo
I-paroxysmal supraventricular tachycardia e- ECG inqunywe ngokuthi:
- ukuguqulwa kwezinyo P;
- ukubeka izinyo P ku-T;
- izinkimbinkimbi ezingenakushintshwa;
- ilungile, kodwa ishyindo esheshayo ngokushesha.
Njengezindlela ezengeziwe zokuhlolwa, i-ultrasound ne-tomography ingasetshenziswa.
Lesi sifo asivame ukuhlotshaniswa nezilonda eziphilayo ze-muscle yenhliziyo noma ukwephulwa komsebenzi we-ventricle kwesokunxele, ngakho-ke izazi ngokuvamile zinikezela ngokucacile ekwelapheni kwe-tachycardia ephezulu ye-paroxysmal.
Ukunakekelwa okuphuthumayo kwe-tachycardia ephezulu ye-paroxysmal
Ukumisa ukuhlaselwa kwe-PNT, lezi zindlela ezilandelayo zisetshenziswa:
- Ukugcina umoya wokuphefumulela ngokucindezeleka ngesikhathi esisodwa komshini wesisu.
- Ukucwiliswa emanzini ebusweni kubhekene nomoya wokuphefumula wamaminithi angu-15.
- Ukucindezela emthini we-carotid efanele ngenkathi isiguli sigqoloke ngemuva.
- Ukucindezelwa ngokucophelela kuma-eyeballs.
- Ukusebenzisa i-ice eyomile entanyeni.
Ukwelashwa kwezidakamizwa ukusetshenziswa kwemithi:
- I-Verapamil , i-adenosine triphosphate (ilawulwa ngokuqondile);
- I-Novokainamid isisombululo se-glucose noma i-Metazone;
- I-Aymalin;
- I-Amiodarone;
- Digoxin;
- I-Dizopyramide;
- I-Propranol.
Ngokunciphisa okukhulu ekucindezelweni, izindlela ezilandelayo zokwelapha zibekiwe:
- ukwelashwa kwe-electropulse;
- ukuhamba nge-cardiac nge-probe electrode.
Ukusebenza nge-tachycardia ephezulu ye-paroxysmal
Inkambo enzima yalesi sifo kanye nokumelana nemithi esetshenzisiwe kuyinkomba yokuhlinzwa. Inhloso yokuqeda imithombo engavamile yesigqi ngosizo lwemisebe ye-laser, imiphumela yamanje, njll. noma ukufakwa kwe-pacemaker, okuqhubekayo ngokuzenzekelayo ngesikhathi sokuhlaselwa futhi iphela ukusebenza ngemva kokubuyisela isigqi senhliziyo.
Ukwelashwa kwemithi ye-paroxysmal ephezulu ye-tachycardia
Ukwelashwa kwe-PNT kusizwa ngemithi yendabuko. Amaphutha asebenzayo asekelwe ku:
- uthando;
- amajikijolo we-viburnum;
- wavuka ezinqulwini;
- impande ye-valerian;
- i-motherwort;
- hawthorn
