Ta yaya ake ƙididdige rashin daidaituwa a cikin girman girman ko ma'aunin tsawon lokaci akan ECG?
Ma'auni na girman ko tsawon lokaci akan ECG suna da mahimmanci don ƙayyade aikin zuciya na yau da kullun. Waɗannan ma'aunai suna bayyana ko ana gudanar da aikin lantarki na tsokar zuciya daidai kuma ko bugun zuciya na yau da kullun. P kalaman, hadaddun QRS, tazarar PR, tazarar QT, da sashin ST su ne manyan abubuwan da aka yi amfani da su a cikin wannan kima.
1. P Ruwa
• Nisa (Lokacin):
• Karnuka: Matsakaicin 0,04 seconds (ƙananan murabba'i 2). Matsakaicin 0,05 seconds (ƙananan murabba'i 2,5) don manyan nau'ikan.
• Cats: Matsakaicin 0,04 seconds (ƙananan firam 2).
• Tsawo:
• Karnuka: Matsakaicin 0,4 mV (kananan murabba'ai 4).
• Cats: Matsakaicin 0,2 mV (kananan murabba'ai 2).
Halin da ba na al'ada ba:
• Faɗin P kalaman, yawanci ana haɗa shi da haɓakar bugun jini na hagu (P mitrale).
• Dogon P kalaman (ƙara girman girman) na iya ba da shawarar haɓakar bugun jini na dama (P pulmonale).
2. Tazarar PR
• Ma'anar: Lokaci ne daga farkon igiyar P zuwa farkon hadaddun QRS. Yana nufin lokacin tafiyar da wutar lantarki daga atria zuwa ventricles.
• Darajoji na yau da kullun:
• Karnuka: 0,06 - 0,13 seconds (ƙananan murabba'i 3 - 6,5).
• Cats: 0,05 - 0,09 seconds (ƙananan murabba'i 2,5 - 4,5).
Halin da ba na al'ada ba:
• Dogon Tazarar PR: Yana iya nuna matsalolin gudanarwa kamar toshewar atrioventricular (AV).
• Gajeren Tazarar PR: Ana iya ganin shi a cikin yanayi irin su WPW (Wolff-Parkinson-White) ciwo.
3. Rukunin QRS
• Nisa (Lokacin):
• Karnuka: Don ƙananan nau'o'in, matsakaicin shine 0,05 seconds (ƙananan murabba'i 2,5). Don manyan nau'ikan, matsakaicin shine 0,06 seconds (kananan murabba'ai 3).
• Cats: Matsakaicin 0,04 seconds (ƙananan firam 2).
• Tsawo:
• Karnuka: Tsayin R: Matsakaicin 2,5 mV (kananan murabba'ai 25) a cikin ƙananan nau'ikan, matsakaicin 3,0 mV (kananan murabba'ai 30) a cikin manyan nau'ikan.
• Cats: Tsawon igiyar R: Matsakaicin 0,9 mV (kananan murabba'ai 9).
Halin da ba na al'ada ba:
• Faɗin QRS Complex: Yana iya nuna toshe reshe (dama ko hagu), tachycardia na ventricular, ko hypertrophy na ventricular.
• Rukunin Rukunin QRS: Yawanci yana nufin rhythms na asalin supraventricular (misali sinus rhythm ko atrial tachycardia).
4. Tazarar QT
• Ma'anar: Lokaci ne daga farkon hadaddun QRS zuwa ƙarshen T kalaman. Yana wakiltar depolarization da repolarization lokaci na ventricles.
• Darajoji na yau da kullun:
• Karnuka: 0,15 - 0,25 seconds (ƙananan murabba'i 7,5 - 12,5).
• Cats: 0,12 - 0,18 seconds (ƙananan murabba'i 6 - 9).
Halin da ba na al'ada ba:
• Dogon Tazarar QT: Ana iya haɗawa da rikicewar electrolyte (misali, hypocalcemia ko hypokalemia), hypothyroidism, ko tasirin magunguna.
• Short Tazarar QT: Ana iya gani saboda hypercalcemia.
5. Bangaren ST
• Ma'anar: Ita ce madaidaiciyar layi daga ƙarshen hadaddun QRS zuwa farkon igiyar T. Wannan ɓangaren yana wakiltar ɗan gajeren lokacin hutu na ventricles bayan sake dawo da su.
• Darajoji na yau da kullun:
• Karnuka: Kada a sami bakin ciki na ST (ba fiye da 0,2 mV ko 2 ƙananan murabba'ai ba).
• Cats: Kada a sami haɓakar ɓangaren ST (ba fiye da 0,15 mV ko ƙananan murabba'i 1,5 ba).
Halin da ba na al'ada ba:
• Girman sashin ST: Yana iya nuna ciwon zuciya na zuciya, pericarditis, ko hyperkalemia.
• Yanki na ST: Za a iya haɗawa da ischemia na myocardial ko hawan ventricular.
6. T Ruwa
• Ma'anar: Yana wakiltar repolarization na ventricles.
• Darajoji na yau da kullun:
• Karnuka: Yana iya zama tabbatacce, korau, ko biphasic. Girman girman bai kamata ya wuce kashi ɗaya cikin huɗu na hadaddun QRS ba.
• Cats: Yawancin lokaci yana iya zama tabbatacce, korau, ko biphasic. Matsakaicin girman: 0,3 mV (ƙananan murabba'ai 3).
Halin da ba na al'ada ba:
• Babban T Wave: Hyperkalemia na iya nuna hypertrophy na ventricular ko ischemia myocardial.
• Lebur ko mara kyau T Wave: Yana iya nuna rashin daidaituwa na electrolyte ko matsalolin myocardial.
Menene iyakokin amfani da electrocardiography (ECG)?
ECG hanya ce mai inganci don tantance bugun zuciya da bugun zuciya. Duk da haka:
• Hankalinsa yana da iyaka: Ba shi da hankali fiye da echocardiography, musamman a gano canje-canjen tsari kamar haɓaka tsokar zuciya.
• riba: Kayan aiki ne mai sauri kuma mai inganci don kimanta arrhythmias, rikicewar tafiyarwa da hauhawar jini na ventricular.
