I-Implantable cardioverter-defibrillators (ICDs)

I-implantable cardioverter-defibrillator (ICD) iyidivayisi encane esebenza ngebhetri ebekwa esifubeni. Ibonisa futhi imisa ukushaya kwenhliziyo okungajwayelekile, okubizwa nangokuthi i-arrhythmias. I-ICD ihlola njalo ukushaya kwenhliziyo. Ihlinzeka ngamashoki kagesi, uma kudingeka, ukubuyisela i-rhythm yomzimba evamile.

I-ICD ihlala ihlola ukushaya kwenhliziyo okungajwayelekile futhi izama ngokushesha ukuyilungisa. Iyasiza uma kukhona ukulahleka ngokuzumayo kwemisebenzi yonke yenhliziyo, isimo esibizwa ngokuthi ukumima kwenhliziyo. I-ICD iyindlela ebaluleke kakhulu yokwelapha noma ubani ohlangane nokumima kwenhliziyo. Lezi zinto zisetshenziswa kakhulu kubantu abanosongo olukhulu lokumima kwenhliziyo ngokuzumayo. I-ICD inciphise ingozi yokufa ngokuzumayo okuvela ekumiseni kwenhliziyo ngaphezu kwemithi kuphela. Udokotela wakho wenhliziyo angakuncoma i-ICD uma unezimpawu zokushaya kwenhliziyo okungajwayelekile okubizwa ngokuthi i-tachycardia ye-ventricular ehlala njalo. Ukuphelelwa amandla kuyinye yezimpawu. I-ICD ingase futhi iqulwe uma uphile ekumiseni kwenhliziyo noma uma una: Umlando wesifo se-coronary artery nesigameko senhliziyo esibuthakathaka inhliziyo. Imisipha yenhliziyo eyongeziwe. Isimo senhliziyo esiyifa esandisa ingozi yokushaya kwenhliziyo okusheshayo kakhulu, njengamanye ama-long QT syndrome.

Izingozi ezingase zenzeke ngenxa ye-implantable cardiac defibrillators (ICDs) noma ukuhlinzwa kwe-ICD kungafaka: Ukutheleleka endaweni efakwe idivayisi. Ukukhula, ukuphuza igazi noma ukubulala. Ukonakala kwezinsimbi zegazi ngenxa yama-wires e-ICD. Ukuphuza igazi eduze kwenhliziyo, okungaba yingozi eyingozi. Igazi liphuma nge-valve yenhliziyo lapho kufakwe i-ICD lead. Ukuqhekeka kwesibindi. Ukuhamba kwedivayisi noma ama-leads, okungabangela ukubhoboka noma ukugqwala emshinini wenhliziyo. Le nkinga, ebizwa ngokuthi i-cardiac perforation, ayivamile.

Ngaphambi kokuthola i-ICD, kwenziwa ukuhlolwa okuningi ukuhlola impilo yentliziyo yakho. Ukuhlolwa kungafaka: I-Electrocardiogram (ECG noma EKG). I-ECG ukuhlolwa okusheshayo nokungenazinkinga okuhlola ukushaya kwenhliziyo. Ama-patches anamathelayo abizwa ngama-electrodes abekwa esifubeni, ngezinye izikhathi ezandleni nasezinzwaneni. Amakhebula ahlanganisa ama-electrodes kukhompyutha, ebonisa noma iphrinta imiphumela yokuhlolwa. I-ECG ingabonisa uma inhliziyo ishaya ngokushesha kakhulu noma kancane kakhulu. I-Echocardiogram. Lolu hlolo lwemiqondo lusebenzisa amaza omsindo ukudala izithombe ezihambayo zenhliziyo. Ibonisa usayizi nesakhiwo senhliziyo nokuthi igazi ligeleza kanjani enhliziyweni. Ukuqapha kwe-Holter. I-monitor ye-Holter iyidivayisi encane, egqokwayo egcina ilandelela izinga lokungqongqoza kwenhliziyo. Ngokuvamile uyigqoka izinsuku eziyi-1 kuya kwezi-2. I-monitor ye-Holter ingakwazi ukubona izinga lokungqongqoza kwenhliziyo ezingavamile ezingabonakali yi-ECG. Amakhebula avela kubaphindi abanamathisela esifubeni ahlanganisa nedivayisi yokurekhoda esebenza ngebhethri. Uthwala le divayisi ephaketheni noma uyigqoka ebhande noma ebhande legama. Ngesikhathi ugqoka i-monitor, ungacelwa ukuba ubhale imisebenzi yakho nezimpawu zakho. Iqembu lakho lokunakekelwa kwempilo lingaqhathanisa amanothi akho nemiqondiso yedivayisi futhi lizame ukuthola imbangela yezimpawu zakho. I-monitor yesigameko. Le divayisi ye-ECG ephathekayo ihloselwe ukugqokwa izinsuku ezingafika kwezingu-30 noma uze ube ne-arrhythmia noma izimpawu. Ngokuvamile ucindezela inkinobho lapho izimpawu ziveleka. Ukuhlolwa kwe-electrophysiology, okuthiwa futhi i-EP study. Lolu hlolo lungase lenziwe ukuqinisekisa ukuxilongwa kokushaya kwenhliziyo okusheshayo. Futhi lingakwazi ukubona indawo enhliziyweni ebangela ukushaya kwenhliziyo okungavamile. Udokotela uqondisa ithyube elithambile elibizwa ngokuthi i-catheter ngomthambo wegazi uya enhliziyweni. Ngokuvamile kusetshenziswa i-catheter engaphezu kweyodwa. Abaphindi ekupheleni kwale catheter barekhoda izibonakaliso zenhliziyo.
