Multifocal atrial tachycardia

Multifocal atrial tachycardia (MAT) inokurumidza kurova kwemoyo. Izvo zvinoitika kana akawandisa masign (magetsi emagetsi) anotumirwa kubva kumusoro kwepamoyo (atria) kuenda kumoyo wezasi (ventricles).

Mwoyo wemunhu unopa simba remagetsi, kana zviratidzo, izvo zvinotaurira kuti rirove. Kazhinji, zviratidzo izvi zvinotanga munzvimbo yekamuri yekumusoro kurudyi inonzi iyo sinoatrial node (sinus node kana SA node). Iyi node inoonekwa semoyo "wakasununguka pacemaker." Inobatsira kudzora kurova kwemoyo. Kana moyo ukaona chiratidzo, inobata (kana kurova).

Iyo yakajairika kurova kwemoyo muvakuru ndeye makumi matanhatu kusvika zana zana kurova paminiti. Iyo yakajairwa kurova kwemoyo inokurumidza muvana.

MuMAT, nzvimbo zhinji mumatanho emoto eatria panguva imwe chete. Zviratidzo zvakawandisa zvinotungamira kukurumidza kurovera kwemoyo. Inowanzo kuve pakati pemakumi zana kusvika zana nemakumi matatu emabheti paminiti kana kupfuura muvakuru. Iyo inokurumidza kurova kwemoyo inokonzeresa kuti moyo ushande zvakanyanya uye usingafambise ropa zvine mutsindo. Kana kurova kwemoyo kuchikurumidza, pane nguva shoma yekukamuri yemoyo kuzadza neropa pakati pekurova. Naizvozvo, hapana ropa rakakwana rinoputirwa kuuropi uye nemutumbi wese nekusara kwega kwega.

MAT inowanzoitika muvanhu vane makore makumi mashanu zvichikwira. Inowanzoonekwa kune vanhu vane mamiriro ezvinhu anoderedza huwandu hweoksijeni muropa. Aya mamiriro anosanganisira:

• Hutachiona mabayo
• Chirwere chisingaperi chinodzivirira pulmonary chirwere (COPD)
• Kuunganidzwa kwemoyo kukundikana
• Kenza yemapapu
• Kukundikana kwemapapu
• Pulmonary embolism

Unogona kuve panjodzi yakakwira yeMAT kana iwe uine:

• Coronary chirwere chemoyo
• Chirwere cheshuga
• Akave nekuvhiyiwa mukati memavhiki matanhatu apfuura
• Kunyanyisa pamushonga theophylline
• Sepsis

Kana kurova kwemoyo kuri pasi pezana kurova paminiti, iyo arrhythmia inonzi "inodzungaira atrial pacemaker."

Vamwe vanhu vanogona kunge vasina zviratidzo. Kana zviratidzo zvikaitika, zvinogona kusanganisira:

• Kusunga pachifuva
• Musoro wakareruka
• Kufenda
• Kunzwa kwekunzwa moyo kuri kurova zvisina kujairika kana nekukurumidza (palpitations)
• Kufema kwekufema
• Kurera huremu uye kutadza kubudirira muvacheche

Zvimwe zviratidzo zvinogona kuitika nechirwere ichi:

• Kufema kunetseka kana wakarara pasi
• Dzungu

Bvunzo dzepanyama dzinoratidza kukurumidza kusingaite kurova kwemoyo kweanopfuura zana kurova paminiti. Ropa kumanikidza kwakajairika kana kuderera. Panogona kunge paine zviratidzo zvekushomeka kwekupararira.

Kuyedza kuongorora MAT kunosanganisira:

• ECG
• Electrophysiologic kudzidza (EPS)

Mwoyo monitors inoshandiswa kurekodha kurovera kwemoyo kunokurumidza. Izvi zvinosanganisira:

• 24-awa Holter yekutarisa
• Inotakurika, yakareba-refu loop zvinyorwa zvinokutendera iwe kuti utange kurekodha kana zviratidzo zvikaitika

Kana iwe uri muchipatara, moyo wako mutinhimira uchaongororwa maawa makumi maviri nemana pazuva, zvirinani pakutanga.

Kana iwe uine mamiriro anogona kutungamira kuMAT, iyo mamiriro anofanira kurapwa kutanga.

Kurapa kweMAT kunosanganisira:

• Kuvandudza huwandu hweropa oxygen
• Kupa magnesium kana potasium kubudikidza netsinga
• Kumisa mishonga, senge theophylline, iyo inogona kuwedzera kurova kwemoyo
• Kutora mishonga yekudzora kurova kwemoyo (kana moyo uchimhanya zvakanyanya), senge calcium chiteshi blockers (verapamil, diltiazem) kana beta-blockers

MAT inogona kudzorwa kana iwo mamiriro anokonzeresa kurova kwemoyo nekukurumidza akarapwa uye kudzorwa.

Zvinetso zvinogona kusanganisira:

• Cardiomyopathy
• Kuunganidzwa kwemoyo kukundikana
• Yakaderedzwa kupomba chiito chemoyo

Fonera wako mupi wezvehutano kana:

• Iwe une kukurumidza kana kusajairika kurova kwemoyo nezvimwe zviratidzo zveMAT
• Iwe une MAT uye zviratidzo zvako zvinowedzera, usavandudze nemushonga, kana iwe unovandudza zviratidzo zvitsva

Kuti uderedze njodzi yekukudziridza MAT, kurapa kusagadzikana kunokonzera iko ipapo.
