ECG kudi na asali Manuniya

Electrocardiography ne mai muhimmanci ba masu cin zali hanya domin diagnosing aikin ayyuka na zuciya. Yana dogara ne a kan rajista na lantarki iko a rage infarction, wanda ake nuna a allon ko takarda.

A binciken ya nuna hauhawar jini, ciwon kirji da kuma shortness na numfashi, bayan da shekaru 40, shan taba da kuma high cholesterol a cikin jiki, kafin wani aiki, a lokacin daukar ciki da kuma bayan kamuwa da cuta.

Don gudanar da wani electrocardiogram da ake amfani da musamman na'urar - electrocardiograph tare Game da wayoyin.

ECG kullum halin da wadannan abubuwa:

1. A hakora wanda aka kaddamarda da haruffa P, Q, R, kuma S, T, U.

Ya kamata a lura da cewa hakori P nuna yadda zumudi na atria. Yadda aka saba, ta duration - daga 0.06-0.1 mawadãta - 0.05-2.5 mm.

Lokacin da ECG rate m tare da tunani kididdigar da cewa da nisa daga cikin kalla square a kan takarda, cikinsa da lantarki iko na zuciya, an rubuta, shi ne 0,04 seconds, da kuma tsawo yayi dace da irin ƙarfin lantarki 0.1 millivolts.

ECG kudi ga wasu hakora:

• Tambaya hakori tsawon dole <0.03 tare da awon karfin wuta da - <¼ kalaman mawadãta daga R;

• R hakori ya zama 0.03-0.04 kuma har zuwa 20 mm (ayata5 da V6 za a iya ƙara har zuwa 26).

• S - al'ada duration na kalaman kai 0.03 s, da irin ƙarfin lantarki - <8 a gubar na II, ayata1 iya zama <25;

• ECG: al'ada hakori T-0,16 sec da mawadãta - <1/2 na kalaman R;

• U - kullum - 0,06-16 tare da tsawo daga cikin kalaman ya kamata game da 2-3 mm.

2. jinkiri: PQ (bugun jini yayi dace da nassi tsakanin atrium da ventricle), QT, kuma RR, ST. Last tazara tare da T kalaman characterizes repolarization, wanda faruwa a cikin ventricles na zuciya;

3. A hadaddun aka kuma kimanta QRST, na nuna lantarki systole da ventricles.

Domin da rajista na lantarki hasken dake fitowa a cikin myocardium na uku misali amfani, kazalika da uku fāriya, da kuma shida ECG kirji take kaiwa. A kullum na da sakamakon dogara da sata a cikin abin da duration da mawadãta daga cikin tãguwar ruwa.

Ya kamata a lura da cewa ECG sigar musamman muhimmanci da bincike dabara. ECG kudi na duk abubuwa nuni da tsari da kuma dace mita na contractions daga cikin zuciya, kazalika da al'ada aiki na da direba na kari. A karkashin wasu canje-canje da za a iya gani a gaban arrhythmias, cardiac madugu disturbances ko na yiwu take hakki na tsokar perfusion da ischemia.

ECG kudi mawadãta ne mai muhimmanci ga daidai ganewar asali, tun bayan da karuwa ne zai yiwu a yi magana game da hypertrophy na dacewa da sassan na zuciya, wanda tasowa hauhawar jini da kuma wasu zuciya cututtuka.

Dole ne in ce cewa ECG ne mai araha da kuma m bincike hanya, amma ta babban drawback - da takaice duration na rajista na lantarki hasken dake fitowa, wanda aka rarraba ta zuciya tsoka. Shi ba zai yiwu ya gane da lokaci-lokaci disturbances na zuciya. Don gane da irin munanan electrocardiography monitoring da ake amfani, wanda aka gudanar na tsawon sa'o'i 48 da kuma samar da wani karin cikakken hoto na aiki na myocardium.

Bugu da ƙari, domin da bambanci ganewar asali na Organic da kuma aikin cuta a cikin zuciyar iya yi ECG orthostatic kaya ko hyperventilation, kazalika a lokacin gwamnatin raba formulations (magunguna samfurori).
