Tachycardia

Ingaphezulu kwesahlulo sazo zonke ukufa ezihambisana nentlungu yeentliziyo zenzeka ngokukhawuleza. Esinye sezizathu eziphambili zezibalo ezidakisayo yi-tachycardia ye-ventricular. Le ntsholongwane ibonakaliswe yinto yokubonakala kweengxube ezilandelanayo (ukususela kwi-3), ezibangela ukuphambana kwentliziyo kunye nokuphindaphinda kwama-120 ngamaxesha ngomzuzu.

Iimpawu ze-tachycardia ye-ventricular

Ubungakanani bobunzima beempawu zeklinikhi zesi sifo kuxhomekeke kwimilo yayo.

I-tachycardia engenamandla engapheliyo, njengomthetho, ivela ngaphandle kwempawu ecacileyo. Olu hlobo lwesifo luhamba kunye nokuhlaselwa kwe-arrhythmia, ehamba ngokukhawuleza kwaye ingabonakali. Kule meko, ifomu elingaqinisekanga le sifo libhekwa njengelona liyingozi kakhulu, kuba lidibanisa eliphakathi phakathi kwe-trigger arrhythmia kunye ne-fibrillation ye-ventricular. Kwimeko yokugqibela, ukufa ngokukhawuleza kubakho.

Uhlobo olusisigxina lwe-tachycardia lubonakaliswe kukuhlaselwa kwangaphambili kweentliziyo ezininzi (ngaphezulu kweemitha ezi-30). Njengemibonakaliso yeklinikhi, ukuphazamiseka kwe-hemodynamic ye-cardiac umsebenzi ngokuqhelekileyo kugcinwe.

I-monomorphic ventricular tachycardia ibonakaliswe ngokuqhelekileyo kwezinto ezikhoyo, ubude obufanayo bokuhlaselwa kunye nokubonakala kwezinto ezinobungozi ezingunaphakade. Isingqimba sokusika sinjalo ukususela kuma-100 ukuya kuma-220 ngamaxesha ngomzuzu.

I-tachycardia ye-polymorphic ventricular ihamba kunye nempawu ezifanayo njengefom echazwe ngaphambili, kuphela ziyabonwa ngokungenasiphelo kwaye ukuhluthwa ngalunye kuhlukile.

Iimpawu:

• ukungcola;
• intlungu kwisifuba, ukucima okanye ubunzima;
• kutyhafa ;
• iimbumba ezinamandla;
• uxinzelelo lwegazi oluphantsi;
• ukuphazamiseka kwentliziyo;
• Ukubetha okanye ukuthabatha intlungu phakathi kwesifuba, ngamanye amaxesha unikezela ngengalo engasekhohlo.

Iimpawu ze-ventricular tachycardia kwi-ECG

Xa kungabikho ezinye izifo ezingapheliyo okanye ezinokwakheka komzimba kwi-cardiogram, kukho ukuphambuka kwentliziyo ekhohlo ukuya kwicala lasekunene. Ukuba i-tachycardia iyinkimbinkimbi ngokuxhomekeka kwezilwanyana, ezi zilandelayo zibonakaliswe kwi-ECG:

• ifunyenwe okanye ilula i-sinusoidal complexes;
• ukuhlukana kwamazinyo P;
• i-concordance kunye nenyosi ephakamileyo ye-T (ejoliswe kwicala elingaphambene nolwalathiso lwe-ventricular complex complex);
• Ukuqhelanisa kwangaphambili kwe-axis kwinqanaba le-northwest quadrant ye-cardiogram.

Unyango lwe-tachycardia ye-ventricular

Ukuhlaselwa kwesimo esingaqinisekanga sesifo, esihlala ngaphezu kwesigamu somzuzu, kubalulekile ukuma ngokukhawuleza, ngoku i-cardioversion. Ukuba unyango alusebenzelanga, kufuneka ujobe ngokusesikweni isisombululo seprocainamide okanye i-lidocaine, uphinde uphinde wenze inkqubo. Kwimeko apho ezi ziyobisi zingenawo umphumo ofanelekileyo, i-amiodarone isetyenziswa.

Imiba yokubanjwa kwentliziyo kunye nokusabalalisa kwe-pulse ixhomekeka ngokukhawuleza.

Ukuba i-tachycardia ye-ventric ivela ngasemva kwe-bradycardia, unyango lweziyobisi lunconywa, lujoliswe ekumiseleni izinga lokushaya intliziyo, ukuphelisa iziphazamiso ze-electrolyte, ischemia, i-hypotension, ukubuyiswa kwexabiso legazi. Amachiza akhethwe yi-cardiologist ngamnye.

Indlela efanelekileyo kakhulu yokulwa nokuhlolwa kwezilwanyana ukuhlolwa kwezilwanyana kuyisistim sokufakelwa kwezixhobo zecomputer ezilawula umsebenzi wenhliziyo - i-cardioverter okanye i- pacemaker . Kwakhona, ngamanye amaxesha ukususwa kweendawo ezincinci zemimandla ye-ventricular yonakalisiwe.
