INTERPRETACIJA EKG PDF

Kako bi se razumjeli dobijewni obrasci, korisno je razumjeti teoriju ispoljavanja EKG-a. Dakle, ukupni pravac depolarizacije i repolarizacije proizvodi vektor koji stvara pozitivan ili negativan otklon na EKG-u, u zavisnosti od toga koji je vod doveo do date slike. Naprimjer, depolarizacijom s desna na lijevo proizvodi pozitivan otklon u samim vodovima, jer dva vektora pokazuju isti smjer. P talas predstavlja depolarizaciju pretkomore. QRS kompleks predstavlja depolarizaciju komore. T talas predstavlja repolarizaciju komore.

The arrhythmia drills and quizzes allow you to practice EKG interpretation. What is EKG Interpretation? An electrocardiogram or EKG, is a test that records electrical activity across multiple heart beats and produces an EKG strip that is interpreted by a healthcare professional. How Electrocardiograms Work - EKG Strips To briefly summarize the components of a normal EKG tracings, it consist of waveform components which indicate electrical events during one heart beat.

P wave is the first short upward movement of the EKG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally begins with a downward deflection, Q; a larger upwards deflection, a peak R ; and then a downwards S wave.

The QRS complex represents ventricular depolarization and contraction. The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles. T wave is normally a modest upwards waveform representing ventricular repolarization.

Digital calipers are available to assist in analyzing each EKG practice strip. Feedback is provided after each response. For each EKG arrhythmia we provide multiple electrocardiogram tracings. Tracing features can be measured using our digital calipers. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of intervals and segments and the evaluation of other relevant waves. EKG practice exercises serve to reinforce the lesson content.

Analiza normalnog EKG-a

Sus O electrocardiograma este indicata pentru: - evaluarea unei dureri de piept inexplicabile, in special cand se suspicioneaza un posibil infarct; alte cauze posibile ale durerii de piept ce pot fi diagnosticate printr-o electrocardiograma sunt aritmiile, hipertrofia unei camere peretii camerei sunt ingrosati , inflamatia sacului ce inconjoara inima pericardita , scaderea fluxului sanguin catre inima ischemia ; - monitorizarea activitatii electrice ale inimii; - diagnosticarea hipertrofiei ventriculare; - monitorizarea eficientei si a efectelor secundare ale unor medicamente ce pot afecta activitatea electrica a inimii; - verificarea functionarii unor dispozitive mecanice peacemakere sau defibrilatoare , implantate in inima cu scopul de a mentine regulat ritmul acesteia. O electrocardiograma poate fi folosita pentru a evalua simptomele unei afectiuni cardiace precum o durere inexplicabila de piept, dispnee , ameteli, palpitatii sau o stare de slabiciune sau functia cardiaca, atunci cand exista factori de risc pentru boli cardiace precum diabetul zaharat, hipercolesterolemia , fumatul, hipertensiunea arteriala sau istoric familial de afectiuni cardiace la varste tinere. Pregatirea pentru electrocardiograma Medicul care efectueaza electrocardiograma trebuie informat asupra medicatiei pe care pacientul o are prescrisa. Unele medicamente pot influenta rezultatele electrocardiogramei. Mod de efectuare Sus Electrocardiograma este efectuata de obicei de catre un cadru medical, iar rezultatul este interpretat de catre un medic, precum un internist, un medic de familie, cardiolog sau chirurg. Pacientul primeste de obicei EKG-ul ca dovada a examinarii sale de catre un medic. Electrocardiograful este portabil, astfel incat EKG-ul poate fi efectuat, practic, oriunde.
