8 Ιαν 2024 · Differentiate between right-axis deviation and left-axis deviation based on electrocardiogram patterns. Apply knowledge of vector analysis to interpret electrocardiograms and determine the electrical axis.
To interpret the cardiac axis, one has to determine the relationship between the QRS axis and limb leads of the ECG. Usually, left ventricles makes up most of the heart muscles, so a normal cardiac axis is directed downward and slightly to the left. In a normal axis, QRS is between -30° and +90°.
9 Σεπ 2024 · Abnormal axis deviation, indicating underlying pathology, is demonstrated by: Left Axis Deviation = QRS axis less than -30°. Right Axis Deviation = QRS axis greater than +90°. Extreme Axis Deviation = QRS axis between -90° and 180° (AKA “Northwest Axis”).
19 Φεβ 2009 · The mean frontal plane electrical axis, determined by the vector of the maximal (dominant) QRS deflection, depends on age and body habitus (Table). It shifts to the left with increasing age. In adults, the normal QRS axis is considered to be within −30° and 90°. Left-axis deviation is −30° and beyond.
Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.
The term intraventricular conduction disturbances refers to abnormalities in the intraventricular propagation of supraventricular impulses that give rise to changes in the shape and/or duration of the QRS complex.
