I-Pathology yesigqi senhliziyo, isifo sikaBouveret sichazwa njengokuvela kokushaya kwenhliziyo okungaba imbangela yokungakhululeki nokukhathazeka. Kungenxa yokungasebenzi kahle kwenhliziyo kagesi. Izincazelo.

Isifo sika-Bouveret sibonakala ngokuba khona kwe-palpitations okwenzeka ekuhlaselweni ngezikhathi ezithile ngendlela yokusheshisa kwe-paroxysmal yenhliziyo. Izinga lokushaya kwenhliziyo lingafinyelela ukushaya kwenhliziyo okungu-180 ngomzuzu okungathatha imizuzu embalwa, ngisho namashumi ambalwa emizuzu, bese kungazelelwe kujwayele ukushaya kwenhliziyo okujwayelekile ngomuzwa osheshayo wenhlalakahle. Lokhu kuquleka kungase kuqaliswe umzwelo noma ngaphandle kwesizathu esithile. Kuseyisifo esithambile esingaphazamisi ukusebenza kwenhliziyo ngaphandle kokuquleka okuphindaphindayo okusheshayo (tachycardia). Ayivezi ingozi ebalulekile. Sikhuluma nge-tachycardia lapho inhliziyo ishaya ngaphezu kwamabhithi ayi-100 ngomzuzu. Lesi sifo sivamile futhi sithinta abantu abangaphezu koyedwa kwabangama-450, ngokuvamile kubantu abasha.

Ngaphandle kwemizwa yokushaya kwesifuba, lesi sifo siphinde sibe umthombo wokungakhululeki kwesifuba ngendlela yemizwa yokucindezelwa nokukhathazeka noma ngisho nokwethuka. 

Ukuhlaselwa kwenhliziyo kuqala futhi kuphele kungazelelwe, okubangelwa imizwa, kodwa ngokuvamile ngaphandle kwesizathu esihlonziwe. 

Ukuphuma komchamo kuvamile ngemva kokubanjwa futhi kukhulula esinyeni. Umuzwa wesiyezi, ikhanda elincane noma ukuquleka kungase kwenzeke ngokuquleka isikhashana. 

Ukukhathazeka kuncike ezingeni lesiguli kule tachycardia. I-electrocardiogram ibonisa i-tachycardia evamile ngokushaya okungu-180-200 ngomzuzu kuyilapho izinga lokushaya kwenhliziyo elivamile lisukela ku-60 kuye ku-90. Kungenzeka ukubala ukushaya kwenhliziyo ngokuthatha ukushaya kwenhliziyo esihlakaleni, lapho umthambo ojikelezayo udlula noma ngokulalela inhliziyo i-stethoscope.

Ngaphezu kwe-electrocardiogram ezofuna ukuhlukanisa isifo sika-Bouveret kwezinye izifo zesigqi senhliziyo, ukuhlolwa okujulile kwesinye isikhathi kuyadingeka lapho ukulandelana kokuhlaselwa kwe-tachycardia kukhubaza nsuku zonke futhi / noma kwesinye isikhathi kuholela esiyezi, isiyezi noma isiyezi. . ukulahlekelwa ukwazi isikhashana. 

Udokotela wenhliziyo ube eserekhoda ukusebenza kukagesi wenhliziyo esebenzisa uphenyo olufakwe ngqo enhliziyweni. Lokhu kuhlola kuzokwenza ukuhlaselwa kwe-tachycardia okuzorekhodwa ukuze kubonakale ngeso lengqondo i-node yezinzwa odongeni lwenhliziyo olubangela i-tachycardia. 

Uma kungakhubazeki kakhulu futhi kubekezelelwe kahle, isifo sika-Bouveret singelashwa nge-vagal maneuver evuselela i-vagus nerve ehilelekile ekulawuleni ukushaya kwenhliziyo (ukubhucungwa kwama-eyeballs, imithambo ye-carotid entanyeni, ukuphuza ingilazi yamanzi abandayo; khuthaza i-gag reflex, njll.). Lokhu kuvuselela kwe-vagus nerve kuzonciphisa ukushaya kwenhliziyo.

Uma lezi ziqondiso zingenele ukudambisa inkinga, izidakamizwa ezilwa nokuvuvukala okufanele zilethwe ngesikhathi, endaweni ekhethekile ye-cadiological, zingajovwa. Bahlose ukuvimba i-intracardiac node ebangela i-tachycardia. 

Uma lesi sifo sibekezelelwa kabi ngamandla nokuphindaphinda kokuhlasela, ukwelashwa okuyisisekelo kunikezwa izidakamizwa ezilwa nesifo sokuqina kwemithambo njenge-beta blockers noma i-digitalis.

Okokugcina, uma ukuthunjwa kungalawulwa, kuphindaphindiwe futhi kukhubaza impilo yansuku zonke yeziguli, kungenzeka, ngesikhathi sokuhlola nge-probe encane engena enhliziyweni, ukwenza isibhamu sokukhipha isisu. i-node ebangela ukuhlaselwa kwe-radiofrequency tachycardia. Lesi senzo senziwa izikhungo ezikhethekile ezinolwazi lwalolu hlobo lokungenelela. Ukusebenza kahle kwale ndlela kungama-90% futhi kuboniswa ezifundweni ezisencane noma ezifundweni ezinokungqubuzana nokuthatha izidakamizwa ezilwa nesifo sokuqina kwemizwa njenge-digitalis.
