Tachycardia inongoreva kurovera kwemoyo nekukurumidza kupfuura zvakajairwa. Iine sinoatrial node, inova yekuberekwa kwemoyo pacemaker, chiyero chemukati chiri pakati pemakumi matanhatu nemazana emabhiti paminiti. Kana iyo mwero ichidarika zana kurova paminiti, tachycardia iripo.

Pakurapa tachycardia, zvakakosha kuti utange kufunga nezve a kubhadhara chikonzero. Muviri unoshandisa kushandisa yakawedzera kurova kwemoyo senzira yekugara uchibhadharisa kana ichinzwa kupera kwekunhuhwirira.

Vaviri veakanakisa dysrhythmics muEMT uye paramedic's turusi bhokisi ndere OXYGEN uye zvakajairika SALINE. Ose marapirwo aya anofanira kuyedzwa asati ashandisa chero mumwe mushonga. Izvo hazvisi zvinobatsira kubvisa inobhadharira tachycardia mune murwere anoida iyo kuti ishandise mafuta. Kuwana iyo chikonzero chekudzikira kweperfusion kungave kwakaringana.

Chimwe chinhu chekufunga nezvacho kutsiga kwemurwere hemodynamic. Iine akarongeka tachycardic mutinhimira mune vasina kugadzikana varwere, yakawiriraniswa cardioversion inoratidzwa. Iko kunoratidzika kuve kune kutya pakati pevanoenda kuchipatara kana zvasvika kune katyamadza vanhu.

The paramedic inoita kunge iri nyore kupa anti-arhythmic / dysrhythmic mishonga kupfuura zvavanoita vachiita moyo. Izvi zviri mu-chokwadi kumashure kufunga. Funga nezvemaonero aKelly Grayson pane dysrhythmic zvinodhaka - iwo anosarudzika cardiotoxins. Kutanga kubva, ivo havawanzo kuwanikwa mumuviri. Chechipiri, ivo vanogaya muviri nekufamba kwenguva uye maitiro anogona kunge asingatarisirwe. Yetatu, ivo vanoshandiswa kurwisa maseru depolarization.

Iwe unoziva zvinoitika mukushaikwa kwema cell depolarization mu myocardium? Asystole - kwete yakafanana divi mhedzisiro, asi inodzosera kumba iyo pfungwa handiti? Zvimwe zvinonetsa, senge yepamusoro-giredhi atrioventricular matombo, uye yakareba QT syndrome inogona zvakare kuitika.

Zvakare, yakawiriraniswa cardioversion haina anenge akawanda seasingadiwe mhedzisiro. Inoshanda nekukurumidza, uye inoenda. Iyo mishonga iwe yaunofanirwa kufunga nezvayo, ndeimwe mhando yekunyaradza kana benzodiazapine isati yaita cardioversion.

Tevere, mushure mekuona kugadzikana kwemurwere hemodynamic, hupamhi hweQRS inofanirwa kutariswa. Kana murwere akatsiga, uye ivo vari mu yakasimba tachycardia, dysrhythmic mishonga inogona kutariswa.

Zvakakosha kuona hupamhi hweQRS, nekuti mishonga yakaita seCardizem (diltiazem), kana Adenocard (adenosine) iyo inogona kupihwa kudzikisira mutinhimira wakaomarara, inogona kuuraya vanhu zvine mutsindo weQRS.

Cherekedza kuti hapana iyo 'ventricular tachycardia' algorithm? Inoti 'Wide QRS', uye inonyora 'isina chokwadi mutinhimira' pazasi. Ichi chirevo chakakosha. Kana iri yakafara, uye usina chokwadi nekwakabva, iri ventricular tachycardia kusvikira zvinonzwisiswa zvimwe.

Chimwe chikonzero chekuti iri WCT nhungamiro uye kwete a ventricular tachycardia mutungamiri imhaka yemamiriro akaita seWPW (wolff parkinson white syndrome). NeWPW, delta wave inogona kunge iripo ichikonzera kuwedzera kweiyo QRS yakaoma.

Izvi zvakakosha nekuti adenosine, uye Cardizem haifanire kupihwa kune varwere vane WPW. Pane gakava pamusoro pekuti Amiodarone yakachengeteka neWPW, asi sezvazvino American Heart Association inozviona sechakachengeteka sarudzo.

Points to remember:

• O2 & zvinwiwa zvemubhadharo tachycardia
•  Kuwirirana kwevhuti yehupenyu ndiyo SAFER chisarudzo
• Kana QRS yakakura zvakanyanya seV-tach
