Since lead I and aVF are perpendicular to each other, you can use those two leads to quickly determine axis. Lead I runs from right to left across a patient's body, positive at the left hand: (See figure 28).If the QRS in lead I is positive (mainly above the baseline), the direction of depolarization will be in the positive half (right half) of the circle above.


This article provides a simple primer on ECGs/EKGs. The 12 leads, or “ECG pictures,” are shown in the ECG strip marked as I, II, II, aVR, AVL, aVF, V1, V2, V3 , 

Electrodes shown from top to bottom are three surface ECGs (1, aVF, V1), Simultaneous ECG tracing (V1) and CS‐78 recording have been  ECG / EKG RESP. T1. T2 !

One row starts with lead I, switches to aVR to be followed by V1, and ends with V4. A second row starts with lead II and records aVL, V2, and V5 in sequence while a third row records lead III, aVF, V3, and V6 in sequence. Start studying ECG module quiz questions.

Using the ECG to localize myocardial infarction / infarction and determine the occluded coronary artery It is often important to be able to determine the localization of myocardial infarction and ischemia, as well as being able to determine which coronary artery that is iccluded, and where the occlusion may be located.

EKG-käyrällä lisälyöntiä seuraa tavallista pitempi tauko. Sydäninfarktissa EKG:hen tulee muutoksia, joista voidaan päätellä, mitä sydämen osaa lihaskuolio on uhkaamassa.

P wave: upright in leads I, aVF and V3 - V6; normal duration of less than or equal to 0.11 seconds Clinical applications of ECG Ambulatory ECG monitoring [41] Description: ECG devices can be used in the outpatient setting to monitor and record the cardiac rhythm over a prolonged period of time. Types. Continuous: Holter monitor [42] A continuous, ambulatory, battery-operated ECG recorder worn for 24–48 hours; Common metrics Sind I oder aVF oder gar beide negativ, kann entweder das EKG verpolt sein, d. h. falsch angelegt, oder es sind mehr oder weniger schwerwiegende Pathologien in Betracht zu ziehen und das nachfolgende Schema für die exakte Lagetypbestimmung anzuwenden. If lead I looks positive and aVF looks negative = left thumb up, right thumb down = LEFT axis deviation If lead I looks negative and aVF looks positive = left thumb down, right thumb up = RIGHT axis deviation You can pretty much see in this ECG that both lead I and lead aVF are positively deflected so therefore the axis is normal 在12導程ecg中,除肢體導程外的所有導程均為單極導程(avr、avl、avf、v 1 、v 2 、v 3 、v 4 、v 5 和v 6 )。 威爾森中央電端 V W 是通過一個電阻網絡將RA,LA,LL電極連接而產生的,代表了身體的平均電壓,並且,這個電壓接近於極大值(即0): Se hela listan på This ECG revealed that the artifact was synchronous with the cardiac cycle, suggesting an arterial pulse-tapping artifact, a condition first described by Aslanger et al. 2,3 There is a clue to identify the problematic electrode from the ECG; the artifact can be observed in leads I, III, aVR, aVL, and aVF, whereas there is no artifact in lead II.
