Mazkur maqolada kardiologiyada keng qo‘llaniluvchi EKG apparatining ishlash
prinsipi hamda funksional tuzilishi tahlil qilindi. Tadqiqotning maqsadi yurak
bioelektrik faolligini qayd etishning fiziologik asoslarini, EKG apparatining asosiy
funksional bloklarini va signalni shakllantirish bosqichlarini ilmiy jihatdan yoritishdan
iborat. Tahlil natijalariga ko‘ra, EKG apparati elektrodlar yordamida yurakdan hosil
bo‘ladigan juda kichik amplitudali signallarni qabul qiladi, ularni differensial
kuchaytirgichlar va filtrlar orqali qayta ishlaydi, so‘ng analog-raqamli o‘zgartirish va
displey yoki printer tizimi orqali vizual shaklda taqdim etadi. Shuningdek, standart 12
ta yetakchi tizim yurakning turli yo‘nalishlardagi elektr faolligini baholashga imkon
berishi aniqlandi. Olingan natijalar EKG apparatini texnik va klinik jihatdan to‘g‘ri
tushunish uning xavfsiz, aniq va samarali qo‘llanilishi uchun muhim ekanini
ko‘rsatadi.
