20.500.12556/DKUM-73421 Analiza modificiranih EKG odvodov Analysis of modified ECG leads Izhodišča in namen: Pri diagnostičnem EKG uporabljamo 10 elektrod in posnamemo 12 različnih odvodov (standardni bipolarni I, II, III, ojačani unipolarni odvodi aVL, aVR, aVF in prekordialni odvodi C1‒C6). Pri EKG monitoringu se uporablja manj elektrod, kjer navadno spremljamo standardne odvode I, II in III. Namen raziskave je bil analizirati, kako modificirati standardne odvode pri EKG monitoringu, da dobimo približne zapise prekordialnih odvodov. Raziskovalna metodologija in metode: V kvantitativni raziskavi smo na zdravih preiskovancih modificirali standardne odvode EKG monitoringa z uporabo defibrilatorja Lifepak 15. Ugotavljali smo, kateri standardni odvod izbrati za zapis in na katera anatomska mesta postaviti elektrode. Uporabili smo diagnostično metodo snemanja EKG zapisov z razširjenim frekvenčnim območjem 0,05 do 150 Hz in monitor metodo, kjer so omenjeni filtri nastavljeni v območju 0,5‒40 Hz. Rezultati: Ugotavljamo, da se v večini primerov pri modificiranih standardnih odvodih uporablja prikaz I. odvoda. Z njim prikazujemo modifikacije bipolarnih odvodov CM5, CS5. CB5 in CC5. Modifikacija MCL1 uporablja III. standardni odvod za prikaz prekordialnega odvoda C1. Stroka si ni popolnoma enotna, ali se modificirana elektroda pri MCL1 odvodu postavi na mesto C1 ali nekoliko nižje desno v 5. medrebrni prostor v srednji klavikularni liniji. Diskusija in zaključek: Uporaba filtrov spremeni EKG zapis v smislu težjega vrednotenja sprememb spojnice ST, zato se filtriranju izogibamo. Ugotovili smo, da nekatere modificirane standardne EKG odvode lahko uporabimo tudi v praksi (monitoring pacienta). 12-kanalni EKG ostaja še vedno zlati standard pri odkrivanju AKS. Purpose: In the diagnostic ECG, 10 electrodes are used and 12 different leads are recorded (standard bipolar I, II, III, reinforced unipolar lead of aVL, aVR, aVF, and precordial leads C1‒C6). In ECG monitoring, less electrodes are used, where usually standard leads I, II and III are monitored. The purpose of the study was to analyse how to modify the standard leads at ECG monitoring to obtain approximate records of precordial leads. Methodology: The research was based on a quantitative methodology. We have found which standard leads to select for recording with using defibrillator LifePak 15, including with anatomical locations where to place electrodes. We were used a diagnostic method of recording ECG records with an extended frequency range of 0,05 to 150 Hz and monitor method, where filters are set within the range of 0,5‒40 Hz. Results: In most modified standard leads is used to display lead I. It shows the modifications of the bipolar leads CM5, CS5. CB5 and CC5. The MCL1 lead modification uses the III lead to display the precordial lead C1. The stroke is not completely uniform if the modified electrode in the MCL1 is placed at the C1 position or slightly lower right in the 5th intercostal space in the middle clavicular line. Discussion and conclusions: In our study, we can confirm of awoiding using filters when recording ECG because we can not reliaby validate changes on ST segment. We can use some of modified standard ECG leads for monitoring patients, but in the end we must confirm that 12-lead ECG is a gold standard for the identification of acute coronary sindrome. snemanje EKG modificirani odvodi miokardni infarkt 12-kanalni EKG 3-kanalni EKG ECG recording modified chest leads myocardial ischemia standard 12-lead 3-lead ECG true false false [M.
