There are some tricks to save you time, but first think about a normal EKG plot; in a normal EKG both leads I and AVF will be positive as the signal travels from the SA node (top right of the heart) to the tip of the ventricles (bottom left of the heart). This is a normal axis, and leads us to the rule of

Watch later. 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 … In electrocardiography, the T wave represents the repolarization of the ventricles.The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period.The last half of the T wave is referred to as the relative refractory period or vulnerable period.The T wave contains more information than the QT interval. Each limb lead I, II, III, AVR, AVL, AVF records from a different angle All six limb leads intersect and visualize a frontal plane The six chest leads (precordial) V1, V2, V3, V4, V5, V6 view the body in the horizontal plane to the AV node The 12 lead ECG forms a camera view from 12 angles 2012-02-12 2020-04-21 270 90 180 0 aVF Lead I The AXIS is the chief direction of QRS propagation in the vaguely To find the Axis in two steps, one must focus on the left side of the ECG. 1) Select the lead with the most isoelectric trace; i.e. the lead in which Q and R waves are of the same height. 2020-08-15 2016-05-19 2008-12-19 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.

• The electrical flow is translated to the ECG as the P wave. The waveform is relatively small – normally between 1.5 and 2.5 mm in width and less than 3 mm in height. PR interval = 0.12 – 0.20 sec (120 – 200 ms) 2018-08-01 Assess Your Patient.
