Uhlelo Olusha Lwemephu Yenhliziyo Lokwelapha Izigqi Zenhliziyo Ezingavamile

“Iziguli eziningi kunanini ngaphambili ziyahlomula ekukhipheni igazi ukuze zelaphe isigqi senhliziyo esingavamile, kanye ne-EnSite X System entsha ka-Abbott ene-EnSite OT, esebenzisa i-Advisor HD Grid catheter, ihlanganisa indlela entsha emisha etholakalayo yokusekela ukwelashwa kwe-arrhythmias yenhliziyo eyinkimbinkimbi neyinselele,” kusho. Amin Al-Ahmad, MD, i-electrophysiologist yenhliziyo yasemtholampilo ene-Texas Cardiac Arrhythmia e-St. David's Medical Center e-Austin, eTexas. “Ukuze siqhubeke nokuthuthukisa imiphumela yeziguli zethu, sidinga uhlelo olunejubane, oluzinzile futhi olunembayo. U-Abbott usinikeze uhlelo olungagcini nje ngokusekela ukwelashwa okuphephile nokusebenzayo, kodwa oluthuthukisa ukunemba kwamamephu, okuvumela ukuqonda okucacile kwalokho okwenzeka enhliziyweni nokuthi yiziphi izindawo okudingeka ziqondiswe ekukhipheni igazi ukuze zelaphe i-arrythmia.”

Lolu hlelo luhlanganisa i-EnSite OT yobunikazi ka-Abbott, esebenzisa i-Advisor™ HD Grid Catheter ukuze inikeze ama-electrogram eqiniso (ama-EGM) kungakhathaliseki ukuthi i-catheter igxile kanjani enhliziyweni. Ngekhono lokusampula ama-EGM ngamadigri angu-360, i-EnSite X EP System ene-EnSite OT ingakwazi ukwenza imephu amaphuzu ayizigidi ezingu-1 enhliziyweni futhi inikeze indawo enembe kakhudlwana yezindawo zokwelapha. Inikeza okungcono kakhulu kokubili izimiso zokulinganisa i-unipolar ne-bipolar, isistimu ihlinzeka ngemephu ngaphandle kokuyekethisa.

Izigidi zabantu baseMelika zithintwa isigqi senhliziyo esingavamile esibangelwa ukuphuka kwemigudu kagesi yenhliziyo. Uma kungelashiwe, lokhu kuphazamiseka kungaholela ekushayeni kwenhliziyo okuguquguqukayo noma kubangele inhliziyo ukuthi ishaye ngokushesha noma kancane kakhulu, okungaba nomthelela omkhulu empilweni yesiguli. I-Atrial fibrillation (AFib), i-arrhythmia evame kakhulu i-EnSite X EP System ene-EnSite OT ingasiza ekwelapheni, isimo lapho amagumbi enhliziyo engavumelani khona, okubangela ukuthi ashaye ngokushesha nangendlela exakile. Kwezinye izimo, i-arrythmias engelashiwe njenge-AFib ingase igcine iholele ekuhlulekeni kwenhliziyo noma unhlangothi.

Ngokukhulayo, odokotela baphendukela ekukhishweni kwenhliziyo ukuze belaphe i-cardiac arrhythmias ngoba -ngokungafani nemithi - ukwelashwa kwelapha isimo emthonjeni ngokuphazamisa indawo yenhliziyo ekhiqiza ukushaya kwenhliziyo okungavamile. Imephu yenhliziyo ibalulekile ekwelashweni okuphumelelayo kwe-ablation ngoba izithombe ezinembe kakhulu, ezinembile nezinemininingwane yenhliziyo zivumela odokotela ukuthi banqume indawo engcono kakhulu yokuthumela ukwelashwa ngokuphepha nangempumelelo.

"Njengoba ukwelashwa kwe-ablation kuya ngokuya kusetshenziselwa iziguli ezilwa ne-cardiac arrhythmias, amathuluzi amasha, amasha futhi athuthukile emephu yenhliziyo kanye ne-imaging abalulekile ukusiza odokotela banikeze imiphumela engcono kakhulu ezigulini zabo," kusho uMike Pederson, iphini likamongameli omkhulu, i-electrophysiology Abbott. “Sithuthukise i-EnSite X System nge-EnSite OT ukuze sithuthukise ukusebenza kwe-catheter yethu ye-Advisor HD Grid eyingqayizivele futhi sivumele odokotela ukuthi bakhe ngokushesha nangokunembile amamodeli enhliziyo esikhathi sangempela, ezinzile, anezinhlangothi ezintathu. Lezi zinhlobo zinikeza indlela yokubona ngokunembile izindawo ezibangela izinkinga, ukuze odokotela belaphe kangcono lezo zigqi zenhliziyo ezingavamile, futhi balondoloze izicubu ezinempilo.”

Ukucabanga Kabusha Amathuba Okwenza Imephu Yenhliziyo

Ekwakheni i-EnSite X System ene-EnSite OT, u-Abbott udale inkundla ukuthi ithuthuke ngesofthiwe entsha, eqinisekisa ukuthi odokotela banokufinyelela kubuchwepheshe bamuva ngokungaguquki ngaphandle kwesidingo sezinhlelo ezintsha ngokuphelele. Ngaphezu kwalokho, i-EnSite X EP System ene-EnSite OT iwuhlelo lokuqala lokuhlela oluvumela odokotela ukuthi bakhethe phakathi kwezindlela ezimbili zokubuka inhliziyo.

Amasistimu okwenza imephu endabuko asebenzisa izimiso zokulinganisa i-unipolar noma i-bipolar. Nakuba ukukalwa kwe-unipolar kunezinzuzo eziningi, okuhlanganisa isiqondiso nesivinini, izilinganiso ze-bipolar zinikeza ukukala kwesignali yendawo ukukhomba izindawo ezikhathazayo. I-EnSite X System ene-EnSite OT iletha imigomo yokulinganisa engcono kakhulu yomibili ndawonye ukuze kukhuliswe ukuqoqwa kwedatha.
