ECG mwero zvinokosha zviratidzi

Electrocardiography unokosha non-invasive nzira nokuda diagnosing ari kushanda basa mwoyo. Zvinonzi kwakavakirwa kunyoresa nemagetsi potentials mukuderedza infarction, izvo anonyorwa chidzitiro kana mapepa.

Ongororo inoratidza BP, chipfuva marwadzo uye kupfupika mweya, pashure pemakore 40, kuputa uye yakakwirira remafuta akawandisa mumuviri, pamberi upi oparesheni, panguva yepamuviri uye pashure chirwere.

Kuti aite unonzi, electrocardiograph rinoshandiswa rinokosha mudziyo - electrocardiograph pamwe nhengo electrodes.

ECG anowanzoita dzinoratidzwa zvinotevera zvinhu:

1. mazino ayo varehwa tsamba P, Q, R, uye S, T, U.

Zvinofanira kucherechedzwa kuti zino P rinoratidza sei excitation yacho atria. Kazhinji, kwayo kwenguva refu - kubva 0.06-0.1 amplitude - 0.05-2.5 mm.

Apo ECG zvazvingava takatsunga tichitaura nenhamba kuti upamhi mudukusa mativi ari papepa, sezvamakaropafadzwa yemagetsi potentials kwemoyo zvinonyorwa, ndiyo 0,04 masekonzi, nokukwirira rinoenderana voltage pakati 0.1 millivolts.

ECG zvazvingava zvimwe meno:

• Q zino pakureba unofanira kuva <0,03 ne Voltage uye - <¼ chinozunguzirwa amplitude kubva R;

• R zino kunofanira 0.03-0.04 uye anosvika 20 mm (V5 uye V6 anogona ngazviwedzerwe kusvika 26);

• S - chakaipa nguva rokuchengeta rinosvika 0,03 s, kuti voltage - <8 mutobvu I II, V1 angava <25;

• ECG: romuzvarirwo zino T-0,16 chik uye amplitude - <1/2 of chinozunguzirwa R;

• U - wokuyera - 0,06-16 pamwe pakakwirira chinozunguzirwa inofanira kuva 2-3 mm.

2. zvikamu: PQ (kupomba anoenderana ndima pakati atrium uye ventricle), QT, uye RR, ST. Last penguva pamwe T chinozunguzirwa ndozvavava repolarization, zvinotora nzvimbo iri ventricles mumoyo;

3. kunzwisisa akanga dzinoongororwa QRST, achiratidza zvemagetsi systole yacho ventricles.

Yokunyoresa magetsi nomunhu ari myocardium neezvitendero matatu kushandiswa, uyewo zvitatu achiomesa matanhatu ECG muchipfuva anotungamirira. Ndozvakajairwa kwemigumisiro kunobva kutapa umo nguva uye amplitude remafungu.

Zvinofanira kucherechedzwa kuti ECG ari chaizvo zvinokosha chirwere unyanzvi. zvazvingava ECG zvose zvinhu anoratidza Nguva uye zvakakodzera kakawanda sunga zvomwoyo, uyewo kuipa nokushanda mutyairi kuti mutinhimira. Under vamwe kuchinja zvinogona kuoneka pamberi arrhythmias, cardiac conduction nenyonganiso kana zvichibvira kutyorwa myocardial perfusion uye ischemia.

ECG zvazvingava amplitude kunokosha kuti zvakarurama nechirwere, sezvo nezvibereko zvayo zvinogoneka kutaura pamusoro hypertrophy kuMudzidzisi zvikamu mwoyo, izvo anovandudza neBP uye zvimwe zvirwere mwoyo.

Ndinofanira kutaura kuti ECG inotengeka uye anodzidzisa chirwere nzira, asi ayo chikuru drawback - pfupi ya kunyoresa magetsi nomunhu, izvo anoparadzirwa ne mwoyo tsandanyama. Hazvibviri kuona periodic vachivavhiringidza nomwoyo. Kuziva abnormalities yakadaro electrocardiography zvichiongororwa rinoshandiswa, iyo inoitwa kwemaawa 48 uye inogovera mufananidzo zvikuru rakazara kushanda myocardium.

Uyezve, nokuti ari differential zvokuongorora pamusoro Organic uye dzichipfekeka zvirwere mumwoyo anogona kuitwa ECG orthostatic mutoro kana hyperventilation, uyewo panguva kwokubatsira yoga Formulations (mishonga ivhu).
