Pathophysiology: Engeri short-circuit ya SVT gy’ekola n’engeri Vagus Nerve gy’emenya loopu¶

Mu mutima omulamu nga guwummudde, buli kukuba kw’omutima kutandikira ku kiziyiza eky’obutonde mu kisenge eky’okungulu ekya ddyo (the sinoatrial [SA] node), kutambula okuyita mu bisenge eby’okungulu (atria), kuyimirira okumala \(0.1\text{ seconds}\) ku kifo kimu eky’amasannyalaze ekisasulwa mu makkati g’omutima (the atrioventricular [AV] node), n’oluvannyuma ne kutambula wansi mu kupampagira wansi ebisenge (ventricles) ku \(60\text{ okutuuka ku }100\text{ emiggo buli ddakiika}\).

Mu Paroxysmal Supraventricular Tachycardia (PSVT / SVT), omuntu azaalibwa n’ekkubo ly’amasannyalaze ery’enjawulo erya microscopic eritali lya bulabe, oba emirongooti ebiri egy’enjawulo munda mu AV node yennyini (AV Nodal Reentrant Tachycardia [AVNRT], ekola ebitundu 60% ku SVT) oba an extra microscopic muscle bridge okugatta omusuwa n’omusuwa (Atrioventricular Reciprocating Tachycardia [AVRT], ekola ebitundu 30% ku SVT, omuli Wolff-Parkinson-White [WPW] syndrome): 1. Engeri "Light Switch" gy'efuumuuka: Olutindo olumu lutambuza amasannyalaze mangu naye nga luddamu mpola (ekkubo ery'amangu), ate olutindo olwokubiri lutambuza mpola naye nga ludda mangu (ekkubo empola). Bwe okukonziba kw’emisuwa okwa bulijjo, okutali kwa bulabe (skipped beat / PAC) kukuba ku milisekondi yennyini ng’olutindo olumu luwummudde ate olulala nga luggule, ekiwujjo ky’amasannyalaze kiyingira mu luguudo oluggule ne kyetooloola mu nkulungo ku \(160\text{ okutuuka ku }250\text{ revolutions per minute}\) (a reentry circuit). 2. Lwaki Abalwadde Bawulira Nga Bakuba Mu bulago ("The Frog Sign"): Mu AVNRT, ebisenge eby'okungulu (atria) n'ebisenge ebya wansi (ventricles) bikuba amasasi ku millisecond y'emu ddala. Olw’okuba vvaalu ya tricuspid wakati w’omusuwa ogwa ddyo n’omusuwa ogwa ddyo ekubwa n’eggalwa ng’omusuwa ogwa ddyo gukonziba, emmundu z’omusaayi zidda emabega waggulu mu emisuwa egy’omunda egy’omu bulago, ne zikola okukuba okulabika, okw’ennyimba ku musingi gw’ensingo (Akabonero k’Ekikere”) okwawula ennyo SVT ku kulumbibwa kw’okutya oba sinus tachycardia. 3. Lwaki abalwadde bafuka nnyo mu kiseera oba amangu ddala nga bamaze SVT: Emisuwa bwe gigolola ku valve eziggaddwa ku \(200\text{ bpm}\), ekinywa ky’omutima kifulumya obusimu obuyitibwa Atrial Natriuretic Peptide (ANP), obugamba enkizi okuyiwa omusulo omunene omutangaavu (tachycardia-induced polyuria) mu bbanga lya 20 to Eddakiika 60. 4. Engeri Vagal Maneuvers (ne IV Adenosine) gye zimenya Loop: Zombi AVNRT loop ne AVRT loop zirina okuyita mu AV node ku buli lap emu. Vagus Nerve (Cranial Nerve X) ya waya butereevu mu AV node ne efulumya acetylcholine, ekikendeeza mu bufunze okutambuza okuyita mu AV node okumala sekondi 2 ku 3. Singa okola okusimbula okw’amaanyi ekimala okw’emirimu gy’obusimu bwa vagus okuziyiza Omu luuyi emu yokka munda mu AV node, ekisaawe ky’empaka eky’amasannyalaze ekyekulungirivu kikuba ekizibiti ky’ekkubo, ne kizikira amangu ago, era ekyuma ekikuba omukka eky’obutonde ekya SA node pacemaker kidda right back over ku \(70\text{ okutuuka ku }90\text{ bpm}\).

Okukola mu mitendera ku mutendera gwa REVERT Modified Postural Valsalva Maneuver¶

Okumala emyaka mingi, obujjanjabi obusookerwako obwa bulijjo bwasomesa "classic sitting Valsalva maneuver" (okutuula nga weegolodde n'okugumira wansi ng'omuntu alina ekyenda), ekyatuuka ku buwanguzi mu abalwadde abatakka wansi wa 15 ku 17 ku buli 100 ab'abalwadde ab'amangu, ne kiwaliriza abalwadde abasukka mu 80 ku buli 100 okufuna adenosine mu misuwa mu kisenge ky'abalwadde ab'amangu.

Mu 2015, ekintu ekikulu REVERT Randomized Controlled Trial ekyafulumizibwa mu The Lancet (Appelboam et al.) kyakyusa enkola y’omutima mu nsi yonna (AHA, ERC, ESC, ne UK NICE/Resuscitation Council) nga kireeta Modified Postural Valsalva Maneuver, ekyayongera ku miwendo gy’okukyusa okuva ku 17% okutuuka ku 43% nga tebalina ddagala ate nga tebalina bikolwa bibi.

Lwaki Standard Valsalva Eremererwa, era Lwaki Okusitula Amagulu okwa Diguli 45 Kukola¶

Enkola ya Valsalva ekola mu emitendera ena egy’omubiri: - Mu kiseera kya Phase I ne Phase II (okukuba kwa sikonda 15), puleesa enkulu munda mu kifuba esika omusuwa oguggalawo, okulemesa omusaayi gw’emisuwa okudda ku mutima. Olw’okuba omusaayi omutono oguyingira mu mutima, puleesa ekka katono, era mu butuufu omubiri gukyuka ON adrenaline (sympathetic tone) ate nga gukyusa OFF the vagus nerve. (SVT kumpi TEYIMIRIRA ng'ofuuwa.) - Obulogo bubaawo mu Phase III ne Phase IV (sekondi 5 ku 20 OLUVANNYUMA lw’okulekera awo okufuuwa): Bw’olekawo okunyigirizibwa n’ossa mu ngeri eya bulijjo, puleesa y’ekifuba ekka okutuuka ku ziro era omusaayi gw’emisuwa ogufuukuuse ne gufubutuka okudda mu mutima. Omusaayi ogwo ogw’amangu gugolola sensa za puleesa (baroreceptors) mu aortic arch ne carotid arteries, ne kivaako okuddamu okunene Vagus Nerve braking reflex (Phase IV vagal overshoot) okuyimiriza SVT. - Lwaki Standard Sitting Valsalva Failed: Bw’osigala otudde nga weegolodde ng’olekera awo okufuuwa, gravity etega omusaayi wansi mu magulu go, kale akatono akatonnya kwokka ke kadda ku mutima gwo (okutondawo Phase IV vagal reflex enafu). - Lwaki REVERT Modification Triples Success: Nga omulwadde afuuwa nga atudde waggulu ku \(45\text{ degrees}\), n'oluvannyuma mu kaseera ako n'asuula torso ye flat (\(0\text{ degrees}\)) nga basitula amagulu gombi okutuuka ku \(45\text{ degrees}\) ku sikonda yennyini gye balekera awo okufuuwa, gravity esuula \(300\text{ ku }500\text{ milliliters}\) omusaayi gw’amagulu ogukuŋŋaanyiziddwa butereevu mu atrium ya ddyo mu kiseera kya Phase III, supercharging Phase IV baroreceptor surge n’okuyimiriza SVT mu sikonda 10 ku 30.

Singa omwana ategeera era ng’assa (oba ng’alagirwa abasindika eby’amangu/omusawo w’omutima gw’abaana), jjuza akaveera omuzira ogumenyese n’amazzi agannyogoga, kazinge mu lugoye lumu olugonvu olunnyogovu, era okiteeke mpola okubuna ekitundu eky’okungulu ekya ffeesi y’omwana (okubikka ekyenyi, amaaso agaggaddwa, n’omutala gw’ennyindo YOKA) for Sekondi 15, okuleka ennyindo n'akamwa ebitundu 100 ku 100 nga tebibikkiddwa era nga birabika. 3. Tokwatangako mwana muwere nga afulumye era tonyiga ku maaso g’omwana oba ekitundu ky’omumwa gwa nnabaana.

Ebigenda mu maaso mu kitongole kya Ambyulensi n'eby'amangu: "Adenosine Moment".¶

Singa Modified Valsalva Maneuver teyimiriza SVT n’ogenda mu kitongole ky’abalwadde ab’amangu, okumanya ky’osuubira kiggyawo okutya: 1. 12-Lead ECG Recording: Nga tebannaba kuwa ddagala lyonna, abasawo abasookerwako oba ba ER nurses bawandiika ECG 12-lead mu kiseera ky’okukuba ennyimba ez’amangu (era bakuuma rhythm strip egenda mu maaso ng’edduka mu kiseera ky’obujjanjabi) omusawo w’omutima asobole okulaba ekika kyennyini ekya SVT n’akebera oba Wolff-Parkinson-White (WPW) delta waves once normal rhythm akomawo. 2. Adenosine mu misuwa (\(6\ekiwandiiko{ mg}\) olwo \(12\ekiwandiiko{ mg}\) Rapid IV Push): - Ku SVT eya bulijjo enfunda-ekizibu, abasawo bateeka IV mu musuwa omunene okumpi n’okukoona kw’enkokola (antecubital fossa) ne bakuba empiso ya adenosine nga bagobererwa amangu ddala \(20\text{ mL}\) saline flush ey’amangu. - Adenosine Kye Awulira (Okukakasa Ekikulu): Adenosine molekyu ya purine ey’obutonde ng’ekitundu ky’obulamu ekitono ennyo obutasukka sikonda 10. Bwe kikuba omutima, kizibira ddala AV node okumala sekonda 3 ku 6 okuddamu okutandika enkola y’amasannyalaze g’omutima. Okumala sekonda 5 ku 10, omulwadde ajja kuwulira ebbugumu ery’amangu ery’okufuukuuka mu kifuba ne mu maaso ge, okuwulira ng’assa mu bbanga akatono, n’okuwulira okwewuunyisa nti omutima gwe gwayimirira, olwo **oluvannyuma lwa sekondi 10 eddagala liva mu mubiri 100 ku buli 100 era omutima gukuba mu bukkakkamu ku \(80\text{ bpm}\). - (Alternative gentler hospital option: Okugezesebwa mu malwaliro okwakakolebwa kulaga nti ebiziyiza emikutu gya calcium mu misuwa nga diltiazem oba verapamil ebiweebwa ng’okufuyira mpola mu IV mu ddakiika 20 bikyusa SVT mu >90% ku balwadde abatebenkevu nga tebalina kuyimirira kwa sikonda 6 okwa adenosine okufuuwa ekifuba.) 3. Okuwona okw’ekiseera ekiwanvu (Catheter Ablation): Oluvannyuma lw’ekitundu kya SVT, okusindikibwa eri omusawo w’amasannyalaze g’omutima (EP) kisobozesa enkola ey’okujjanjaba abalwadde abatali balwadde etali ya maanyi nnyo eyitibwa catheter ablation, ewonya AVNRT ne AVRT/WPW enkalakkalira mu abalwadde 95 ku 98 ku buli 100 kale tebeetaaga ddagala lya mutima buli lunaku.

Ekiwandiiko ky’empuliziganya ekituufu ku 911 / 112 / 999 n’okusunsula mu ddwaaliro¶

Kozesa ebiwandiiko bino ebitegeerekeka obulungi eby’obujjanjabi ng’oyita abasindika eby’amangu oba ng’otuuka mu kusunsula mu ddwaaliro:

• Ku Mutima oguvuganya ogutali munywevu (Obulumi mu kifuba, okussa obumpi, okuzirika, oba obulwadde bw'omutima nga tebunnabaawo):

  "Nneetaaga ambyulensi ey'amangu ng'erina ekyuma ekilondoola omutima/ekiziyiza omutima ku [Exact Address]. Omulwadde wa myaka [Emyaka] ng'omutima gukuba mu bwangu nga [Number] buli ddakiika nga guwerekerwako [obulumi mu kifuba / okussa obubi / okuziyira / okuzirika / ebyafaayo by'okulwala omutima oba omutima okulemererwa). Tuteebereza Ventricular Tachycardia oba unstable arrhythmia era omulwadde agalamidde wansi ng'awummudde ddala."

• Ku Stable Suspected SVT (Bw'ogenda mu ER Oluvannyuma lw'okukyusa Valsalva):

  "Ndi mu kulonda okw'amangu n'omulwadde ow'emyaka [Emyaka] eyafuna 'light-switch' onset regular tachycardia ku nga [180 ku 220] beats buli ddakiika okutandika ku [Time]. Omulwadde ali bulindaala nga talina bulumi mu kifuba, era okugezesebwa emirundi ebiri okwa REVERT Modified Postural Valsalva Maneuver tekwakyusa rhythm. Twetaaga ECG ey'amangu eya 12-lead nga arrhythmia ekola n'okwekenneenya okukyusa SVT."

• Eri Omwana Omuwere alina SVT (\(>220\text{ bpm}\)):

  "Nneetaaga ambyulensi y'abaana ey'amangu ku [Exact Address]. Omwana wange ow'omwezi [Emyaka] ali muddugavu, agaana okuliisa, era alina okukuba kw'omutima okutambula okusukka [220 ku 280] buli ddakiika nga talina musujja. Tuteebereza Infant Supraventricular Tachycardia (SVT)."

Ebibuuzo ebitera okubuuzibwa¶

Lwaki okusitula amagulu gange ku diguli 45 amangu ddala nga mmaze okufuuwa (the REVERT Modified Valsalva) kikola emirundi egisukka mu ebiri nga n’okugumira wansi nga ntudde?¶

Okufuuwa n’amaanyi okumala sekondi 15 kizimba puleesa mu kifuba ekiziyiza omusaayi okudda ku mutima okumala akaseera; the actual vagus nerve surge that stops SVT happens 5 to 20 seconds OLUVANNYUMA lw’okulekera awo okufuuwa, omusaayi bwe gufubutuka okudda mu mutima ne gugolola sensa za puleesa za aorta. Bw’osigala ng’otudde nga weegolodde ng’olekedde awo okufuuwa, amaanyi ag’ekisikirize gatega omusaayi ogwo wansi mu magulu go; nga oteeka omugongo gwo mu bwangu nga guwanvuye n’ositula amagulu go okutuuka ku diguli 45 mu sikonda lw’olekera awo okufuuwa, amaanyi ag’ekisikirize gayiwa ebbidde eddene ery’omusaayi gw’amagulu butereevu mu kifuba kyo, ne kivaako ekyuma eky’amaanyi ekiyitibwa vagus nerve reflex ekiyimiriza SVT mu bantu 43 ku buli 100.

Nsobola ntya okumanya enjawulo wakati w’okutya (sinus tachycardia) ne Supraventricular Tachycardia (SVT)?¶

Wadde nga byombi bireeta omutima okukuba, okutuuyana, n'okuwulira okutya, SVT ekyukakyuka mu kaseera ako mu kukuba kw'omutima gumu (emirundi mingi ng'efukamidde oba ng'etambula mu bwangu) n'ekuba ku ddoboozi eritali lya lwazi 160 ku 250 buli ddakiika n'okukuba okulabika ku musingi gw'ensingo ("Akabonero k'Ekikere"), n'oluvannyuma n'ezikira mu bwangu mu kukuba omulundi gumu. Obulwadde bw’okutya (sinus tachycardia) kweyongera mpolampola mu ddakiika eziwerako, tebutera kusukka 150 ku 160 buli ddakiika mu bantu abakulu, era bukendeera mpolampola mu ddakiika 10 ku 30 ng’okkakkana.

Lwaki kyabulabe omuntu w’omu maka okunsiiga ensingo (carotid sinus massage) oba okunnyiga amaaso okukomya omutima ogukuba enduulu?¶

Okusiiga omusuwa gwa carotid mu bulago kiyinza okwatika ekikuta kya kolesterol ekitannazuulibwa munda mu bbugwe w’omusuwa ne kikuba omusaayi butereevu mu bwongo, ne kivaako okusannyalala okw’amangu, okusannyalala enkalakkalira. Okunyiga ku bitundu by’amaaso (the oculocardiac reflex) kiyinza okukutuka oba okwekutula retina n’okunyiga eriiso; tewali maneuver yonna erina kukolebwa bweru wa ddwaaliro, naddala nga safe REVERT Modified Valsalva Maneuver ekola bulungi nnyo.

Lwaki nnina okufulumya omusulo ennyo amangu ddala nga mmaze okufuna SVT oba atrial fibrillation?¶

Ebisenge by’omutima gwo ebya waggulu (emisuwa) bwe bikuba ku vvaalu z’omutima eziggaddwa ku sipiidi 180 ku 220 buli ddakiika, ebisenge by’ebinywa by’emisuwa ebigoloddwa bifulumya obusimu obw’obutonde obuyitibwa Atrial Natriuretic Peptide (ANP) mu musaayi gwo. ANP ekola akabonero k’ensigo zo okufulumya amangu sodium n’amazzi okukendeeza ku bungi bw’omusaayi, ekivaako amataba agatali ga bulabe ddala ag’okufulumya omusulo omutangaavu mu kiseera oba mu ddakiika 30 oluvannyuma lw’ekitundu ky’omutima ogudduka.
