19 Mar 2021 A thorough ECG interpretation algorithm should assess: Heart rhythm (best seen in lead II). Heart rate. (any lead); Cardiac axis (leads I and aVF).

Thus, we obtain additional 'Goldberger augmented' limb leads (aVR, aVL, aVF) and the thoracic (V1-V6) leads. Therefore the most common ECG electrocardiagram has currently 12-leads. Under special circumstances, other leads may be used.

Lead II is perpendicular to aVL. STEP 1: Is the QRS in Lead I mostly positive or negative? Since Lead I is the biphasic lead and AVF is positive, the classification is Normal Axis +90 Degrees. aVF means augmented Vector Foot; the positive electrode is on the foot.

2017年2月15日 如果病人左右手位置或貼片位置改變，向量投影結果不就有大影響嗎？ 例如：右手 摸頭、左手摸肚子，本來的Lead I不就變成aVF？ 我知道這問題很 

The most efficient way to estimate axis is to look at LEAD I and LEAD aVF. Examine the QRS complex in each lead and determine if it is Positive, Isoelectric (Equiphasic) or Negative: A positive QRS in Lead I puts the axis in roughly the same direction as lead I. A positive QRS in Lead aVF similarly aligns the axis with lead aVF.

All the important intervals on this recording are within normal ranges. 1. P wave: upright in leads I, aVF and V3 - V6; normal duration of less than or equal to 0.11

A 12-lead ECG consists of three bipolar limb leads (I, II, and III), the unipolar limb leads (AVR, AVL, and AVF), and six unipolar chest leads, also called precordial or V leads, (, , , , , and ). Limb leads: I, II, III, IV, V, and VI. Lead IV also called AVR. 2014-12-30 · Leads II and aVF are now perfectly clear and lead III has improved substantially. The machine’s measurements changed slightly but my eyes can’t see any difference. The different measurements might even be due to the cleaner baseline, meaning the the second ECG could have more accurate computerized numbers despite the leg-switch.

Instead, the limb leads are displayed in two groups of three: leads I, II and III and leads aVR, aVL and aVF. Figure 1 shows the traditional presentation of the 12-lead ECG. This presentation format is the standard in the United States, United Kingdom, most parts of Europe, South America, Asia and Africa.
