Isifundo se-Intracardiac electrophysiology (EPS)

Ucwaningo lwe-Intracardiac electrophysiology (EPS) yisivivinyo sokubheka ukuthi amasignali kagesi enhliziyo asebenza kahle kangakanani. Isetshenziselwa ukuhlola ukushaya kwenhliziyo okungafani noma isigqi senhliziyo.

Ama-electrode wocingo abekwa enhliziyweni ukwenza lokhu kuhlolwa. La ma-electrode alinganisa umsebenzi kagesi enhliziyweni.

Inqubo yenziwa elabhorethri yasesibhedlela. Abasebenzi bazobandakanya udokotela wenhliziyo, ochwepheshe nabahlengikazi.

Ukuze ube nalolu cwaningo:

• Indawo yakho yokubhoboza kanye / noma yentamo yakho izokhucululwa bese kusetshenziswa umuthi wokundikindiki (i-anesthetic) esikhunjeni.
• Udokotela wezinhliziyo uzobe ebeka ama-IV amaningi (abizwa ngokuthi ama-sheaths) endaweni yomgogodla noma yentamo. Uma la ma-IV esekhona, izintambo noma ama-electrode angadluliselwa emigodleni emzimbeni wakho.
• Udokotela usebenzisa izithombe ezinyakazayo ze-x-ray ukuze aqondise i-catheter enhliziyweni futhi abeke ama-electrode ezindaweni ezifanele.
• Ama-electrode athatha amasiginali kagesi enhliziyo.
• Izimpawu zikagesi ezivela kuma-electrode zingasetshenziselwa ukwenza inhliziyo yeqe ukushaya noma ikhiqize isigqi senhliziyo esingajwayelekile. Lokhu kungasiza udokotela ukuthi aqonde kabanzi mayelana nokuthi yini ebanga isigqi senhliziyo esingajwayelekile noma ukuthi iqala kuphi enhliziyweni.
• Unganikezwa nemithi engasetshenziswa ngenhloso efanayo.

Ezinye izinqubo ezingenziwa futhi ngesikhathi sokuhlolwa:

• Ukubekwa kwe-pacemaker yenhliziyo
• Inqubo yokuguqula izindawo ezincane enhliziyweni yakho ezingadala izinkinga zesigqi senhliziyo yakho (okubizwa ngokuthi yi-catheter ablation)

Uzotshelwa ukuthi ungadli noma uphuze amahora ayisithupha kuya kwayisishiyagalombili ngaphambi kokuhlolwa.

Uzogqoka ingubo yasesibhedlela. Kufanele usayine ifomu lokuvuma lenqubo.

Umhlinzeki wakho wezokunakekelwa kwezempilo uzokutshela ngaphambi kwesikhathi uma udinga ukwenza izinguquko emithini oyiphuzayo njalo. UNGAYEKISI ukuthatha noma ukushintsha noma yimiphi imithi ngaphandle kokuqala ukhulume nomhlinzeki wakho.

Ezimweni eziningi, uzonikezwa umuthi ozokusiza uzizwe uzolile ngaphambi kwenqubo. Isifundo singahlala kusuka ehoreni elilodwa kuya emahoreni amaningana. Ungahle ungakwazi ukushayela ekhaya ngemuva kwalokho, ngakho-ke kufanele uhlelele umuntu ozokushayela.

Uzobe uphapheme ngesikhathi sokuhlolwa. Ungazizwa ungakhululekile lapho i-IV ibekwa engalweni yakho. Ungase uzwe nengcindezi ethile kusayithi lapho kufakwa i-catheter. Ungase uzwe inhliziyo yakho yeqa ukushaya noma ukugijima ngezikhathi ezithile.

Umhlinzeki wakho anga-oda lokhu kuhlolwa uma unezimpawu zesigqi senhliziyo esingajwayelekile (i-arrhythmia).

Ungadinga ukuthi ube nezinye izivivinyo ngaphambi kokuba kwenziwe lolu cwaningo.

I-EPS ingenziwa ku:

• Hlola ukusebenza kwesistimu kagesi yenhliziyo yakho
• Khomba isigqi senhliziyo esingajwayelekile (arrhythmia) esiqala enhliziyweni
• Nquma ukwelashwa okungcono kakhulu kwesigqi senhliziyo esingajwayelekile
• Thola ukuthi ngabe usengozini yemicimbi yenhliziyo yesikhathi esizayo, ikakhulukazi ukufa kwenhliziyo okungazelelwe
• Bona ukuthi umuthi ulawula isigqi senhliziyo esingajwayelekile yini
• Bona ukuthi ngabe udinga i-pacemaker noma i-cardioverter-defibrillator (ICD)

Imiphumela engajwayelekile ingahle ibangelwe yimigqi yenhliziyo engajwayelekile ehamba kancane kakhulu noma eshesha kakhulu. Lokhu kungafaka:

• I-Atrial fibrillation noma i-flutter
• Inhliziyo block
• Isifo se-sinus syndrome
• I-Supraventricular tachycardia (iqoqo lesigqi senhliziyo esingajwayelekile esiqala emakamelweni aphezulu enhliziyo)
• I-ventricular fibrillation kanye ne-ventricular tachycardia
• Isifo se-Wolff-Parkinson-White

Kungaba nezinye izimbangela ezingekho kulolu hlu.

Umhlinzeki kufanele athole indawo nohlobo lwenkinga yesigqi senhliziyo ukuze anqume ukwelashwa okufanele.

Inqubo iphephe kakhulu ezimweni eziningi. Izingozi ezingaba khona zifaka:

• I-Arrhythmias
• Ukopha
• Amahlule egazi aholela embolism
• I-tamponade yenhliziyo
• Isifo senhliziyo
• Ukutheleleka
• Ukulimala emthanjeni
• Umfutho wegazi ophansi
• Unhlangothi

Ucwaningo lwe-Electrophysiology - i-intracardiac; I-EPS - i-intracardiac; Isigqi senhliziyo esingajwayelekile - i-EPS; IBradycardia - i-EPS; ITachycardia - i-EPS; Fibrillation - EPS; I-Arrhythmia - i-EPS; Inhliziyo block - EPS

• Inhliziyo - ukubuka kwangaphambili
• Uhlelo lokuqhuba kwenhliziyo
