WebThey are often seen in leads I and aVL when the QRS axis is to the left of +60°, and in leads II, III, aVF when the QRS axis is to the right of +60°. Septal q waves should not be confused with the pathologic Q waves of myocardial infarction. Precordial leads: (see Normal ECG) Small r-waves begin in V1 or V2 and progress in size to V5. WebECG leads: from electrodes to limb leads, chest leads & 12-lead ECG. Before discussing the ECG leads and various lead systems, we need to clarify the difference between ECG leads and ECG electrodes.An …
WebThe QRS axis is perpendicular to that lead's orientation (see above diagram). Since there are two perpendiculars to each isoelectric lead, chose the perpendicular that best fits the direction of the other ECG leads. If there is no isoelectric lead, there are usually two leads that are nearly isoelectric, and these are always 30° apart.
