Tsinga conduction velocity

Tsinga conduction velocity (NCV) bvunzo kuona kuti masasi emagetsi anotsika nekufamba sei mutsinga. Muedzo uyu unoitwa pamwe neelectromyography (EMG) kuongorora mamhasuru ezvakaipa.

Anonamatira zvigamba zvinodaidzwa pamusoro pemvura magesi anoiswa paganda pamusoro pemitsipa munzvimbo dzakasiyana. Chidimbu chimwe nechimwe chinopa simba rakapfava remagetsi. Izvi zvinomutsa tsinga.

Izvo zvinoguma zvaitika zvemagetsi zvetsinga zvakanyorwa nemamwe maelektrode. Iyo daro pakati pemagetsi uye nguva yazvinotora kuti mafungiro emagetsi afambe pakati pemagetsi anoshandiswa kuyera kumhanya kwezviratidzo zvetsinga.

EMG ndeyekurekodha kubva kune tsono dzakaiswa mumhasuru. Izvi zvinowanzoitwa panguva imwecheteyo nemuyedzo uyu.

Iwe unofanirwa kugara pane chaiyo tembiricha yemuviri. Kunyanya kutonhora kana kudziya zvakanyanya kunochinja tsinga kuitisa uye kunogona kupa manyepo mhedzisiro.

Udza chiremba wako kana iwe une chirwere chemwoyo chinonzi defibrillator kana pacemaker. Matanho akakosha anozoda kutorwa usati waedzwa kana uine imwe yemidziyo iyi.

Usapfeke chero mafuta, sunscreen, pefyumu, kana moisturizer pamuviri wako pazuva rekuyedzwa.

Kuda kwacho kunogona kunzwa sekuvhunduka kwemagetsi. Iwe unogona kunzwa kumwe kusagadzikana zvichienderana nekuti simba rakasimba rakadii. Iwe haufanire kunzwa kurwadziwa kana iyo bvunzo yapera.

Kazhinji, iyo nerve conduction bvunzo inoteverwa neelectromyography (EMG). Pamuedzo uyu, tsono inoiswa mumhasuru wobva waudzwa kuti bata kanyama kacho. Maitiro aya anogona kusanzwisisika panguva yekuyedzwa. Iwe unogona kunge uine mhasuru kusuruvara kana kupwanya mushure mekuedzwa panzvimbo iyo tsono yakaiswa.

Bvunzo iyi inoshandiswa kuongorora kukuvara kwetsinga kana kuparadzwa. Iyo bvunzo inogona dzimwe nguva kushandiswa kuongorora zvirwere zvetsinga kana mhasuru, kusanganisira:

• Myopathy
• Chirwere cheLambert-Eaton
• Myasthenia gravis
• Carpal tunnel chirwere
• Tarsal tunnel chirwere
• Chirwere cheshuga neuropathy
• Bhero kuoma
• Guillain-Barré chirwere
• Brachial plexopathy

NCV inoenderana nehupamhi hwetsinga uye mwero weiyo myelination (kuvapo kwemyelin sheath pane axon) yetsinga. Vacheche vacheche vane tsika dzinenge hafu yevakuru. Hunhu hwevakuru hunowanzo svitswa nezera rechitatu kana rechina.

Ongorora: zvakajairika kukosha masenduru anogona kusiyana zvishoma pakati pema laboratories akasiyana. Taura nemupi wako wezvehutano nezve zvinorehwa nemimwe miedzo yako.

Kazhinji kazhinji, mhedzisiro isina kujairika inokonzerwa nekukuvara kwetsinga kana kuparadzwa, kusanganisira:

• Axonopathy (kukuvara kune chikamu chakareba chetsinga cell)
• Kuitisa block (iyo yekudaidzira yakavharirwa kumwe kunhu kwenzira)
• Demyelination (kukuvara uye kurasikirwa kwemafuta ekudzivirira akakomberedza nerve yesero)

Iko kukuvara kwetsinga kana kuparadza kunogona kunge kuri nekuda kwenzvimbo dzakasiyana dzakasiyana, kusanganisira:

• Doro neuropathy
• Chirwere cheshuga neuropathy
• Mitsipa mhedzisiro yeuriremia (kubva mukundikana kwetsvo)
• Kukuvara kunorwadza kune tsinga
• Guillain-Barré chirwere
• Diphtheria
• Carpal tunnel chirwere
• Brachial plexopathy
• Charcot-Marie-Tooth chirwere (nhaka)
• Chisingaperi chinokonzera kupisa polyneuropathy
• Kazhinji peroneal nerve kusagadzikana
• Akasiyana epakati median nerve kusagadzikana
• Hwevakadzi tsinga kusagadzikana
• Friedreich ataxia
• General paresis
• Mononeuritis multiplex (akawanda mononeuropathies)
• Primary amyloidosis
• Radial nerve kusagadzikana
• Sciatic tsinga kusagadzikana
• Sekondari systemic amyloidosis
• Sensorimotor polyneuropathy
• Tibial nerve kusagadzikana
• Ulnar tsinga kusagadzikana

Chero chipi nechipi cheparipheral neuropathy chinogona kukonzeresa zviwanikwa. Kukuvadza kumutsipa wepelinha uye disk herniation (herniated nucleus pulposus) ine nerve midzi kudzvinyirira kunogona kukonzeresa zvisirizvo mhedzisiro.

Chiyero cheNCV chinoratidza mamiriro eakanakisa epamoyo nerve. Naizvozvo, mune dzimwe nguva mhedzisiro yacho inogona kunge yakajairika, kunyangwe paine kukuvara kwetsinga.
