Kunzwisisa ECG: Kusunungura PRT Axes

Electrocardiography (ECG) inoshanda sechinhu chakakosha pakuongorora kushanda kwemagetsi emoyo.Pakati pematanho akaomarara akatorwa pa ECG graph, mazwi akaita se 'PRT axis' anogona kusimuka.Nekudaro, zvakakosha kujekesa kuti maaxes anozivikanwa muECG anonyanya kutarisa paP wave, QRS yakaoma, uye T wave.Ngationgororei kukosha kwemasanhu aya.

1. P Wave Axis

Iyo P wave inomiririra atrial depolarization, chiitiko chemagetsi chinotangira kuputika kweatrial.Iyo P wave axis inotarisa mukati meavhareji nzira yeaya magetsi emagetsi.Inoshanda seyakakosha parameter mukunzwisisa hutano hweatria.

Normalcy Inotsanangurwa: Yakajairwa P wave axis inotangira pa0 kusvika +75 madhigirii.

Anomalies muP wave axis inogona kuunza njodzi dzakasiyana, ichipa mazano akakosha kune ari pasi pemamiriro emoyo:

Kuruboshwe kweAtrial Kuwedzera: Kuenda kuruboshwe kunopfuura +75 madhigirii kunogona kuratidza nyaya dzakadai sehypertension kana chirwere chemoyo chevalvular, zvichibvumidza kuongororwazve.

Right Atrial Kuwedzera: Kutsauka kwekurudyi kunogona kuratidza pulmonary hypertension kana chirwere chemapapu chisingaperi, zvichikurudzira kuongororwa kwakazara kwekufema uye hutano hwemoyo.

2. QRS Complex Axis

Sezvo kutarisa kunochinja kune ventricular depolarization, iyo QRS yakaoma inotora nzvimbo yepakati.Kuratidzira zviitiko zvemagetsi zvinotungamira kune ventricular contraction, iyo QRS yakaoma axis inopa nzwisiso mukati meavhareji nzira ye ventricular depolarization.Kunzwisisa iyi axis kunobatsira mukuongororwa kwehutano hwe ventricular.

Normalcy Inotsanangurwa: Iyo QRS axis inowanzosiyana kubva -30 kusvika +90 madhigirii.

Kutsauka muQRS yakaoma axis inotakura zvakakosha, kutungamira vashandi vehutano mukuona njodzi dzinogona kuitika:

Left Axis Deviation: Axis inochinjika kuruboshwe inogona kuratidza mamiriro akaita se hypertrophy kana conduction abnormalities, zvichikurudzira kunyatso ongorora uye kuongororwa.

Right Axis Deviation: Kutsauka kwekurudyi kunogona kuratidza nyaya dzakadai sepulmonary hypertension kana right ventricular hypertrophy, zvichida kunyatsoongororwa kushanda kwemoyo.

3. T Wave Axis

Iyo T wave inobata chiitiko chemagetsi chakabatana ne ventricular repolarization, ichimaka chikamu chekuzorora.Iyo T wave axis, yakafanana neP wave uye QRS yakaoma axes, inotaridza avhareji kutungamira kwemagetsi emagetsi panguva ye ventricular repolarization.Kutarisa iyi axis inobatsira pakuongorora kwakadzama kwekutenderera kwemoyo.

Normalcy Inotsanangurwa: Yakajairwa T wave axis inosiyana zvakanyanya asi kazhinji iri munzira yakafanana neyeQRS yakaoma.

Anomalies muT wave axis inopa ruzivo rwakakosha munjodzi dzinogona kuitika uye kukanganisa mukudzoreredzwa kwemoyo:

Inverted T Waves: Kutsauka kubva kunzira inotarisirwa kunogona kureva ischemia, myocardial infarction, kana kusaenzana kwe electrolyte, zvichiita kuti vanhu vatarise nokukurumidza uye kuwedzera kuongororwa kwekuongorora.

Flat kana Peaked T Waves: An atypical T wave axis inogona kuratidza hyperkalemia, myocardial ischemia, kana mishonga yemigumisiro, zvinoda kuongororwa kwakakwana kwehutano hwemurwere.

Munharaunda yeECG, mazwi P wave, QRS yakaoma, uye T wave axes anotangwa uye anozivikanwa zvakanyanya.Zvakadaro, izwi rekuti 'PRT axis' rinogona kukonzera kusanzwisisana kana kutadza kutaurirana.Izvo zvakakosha kuti uzive kuti matemo ataurwa pamusoro anoumba ibwe rekona rekududzirwa kweECG.

Kunzwisisa idzi njodzi dzinogona kuitika dzine chekuita neanomalies muP wave, QRS complex, uye T wave axes kwakakosha kune vashandi vehutano.Kuongorora kutsauka kubva pane zvakajairwa mune aya maakisi anobatsira mukukurumidza kuona uye kupindira, kudzikamisa njodzi dzepazasi nyaya dzemoyo.Kuongororwa kweECG nguva dzose, pamwe chete nekuziva nezvenjodzi dzinogona kuitika, zvinobatsira kune yakazara nzira yehutano hwemoyo.
