The ECG is likely one of the most typically used investigations in modern drugs. Interpretation of the ECG can look daunting, however it is admittedly particularly ordinary so long as a scientific procedure is taken.

Pocket ECGs for Nurses

assists with this activity through delivering a close but readable advent to ECG interpretation, supplemented by means of medical information regarding the best way to act in keeping with its findings.

The publication starts off by means of masking the fundamentals of cardiac anatomy and body structure and the way those relate to the ECG. It then courses nurses on tips to practice a superior ECG recording, interpret it and make feel of universal ECG abnormalities. The e-book additionally features a consultant to ambulatory and bedside tracking in addition to necessary bankruptcy summaries.

This pocketbook is a necessary reference for the non-specialist who should be in a position to list and practice a simple and secure interpretation of an ECG. Written in undeniable language with transparent causes, bullet lists and summaries all through, this convenient consultant will profit nurses in addition to paramedics and different allied well-being pros in recording and examining ECGs.

Example text

In the next few chapters, we will be looking at heart rhythms in detail, but let us begin by describing ways to measure heart rate and the abnormalities that can affect it. The term ‘heart rate’ usually means the ventricular rate, which corresponds to the patient’s pulse. Depolarization of the ventricles produces the QRS complex on the ECG, and so it is the rate of QRS complexes that needs to be measured to determine heart rate. The measurement of heart rate is simple and can be done in several ways.

However, the axis is actually fairly straightforward. Indeed, deciding whether the QRS axis is normal can be summarized in one rule: A QUICK RULE FOR ASSESSING THE AXIS If the QRS complexes are predominantly positive in leads I and II, the QRS axis is normal. The QRS axis is an indicator of the general direction that the wave of depolarization takes as it flows through the ventricles – in other words, the overall vector of ventricular depolarization. 6 The overall direction of depolarization of the ventricles (QRS or ‘cardiac’ axis).

The QRS axis is therefore conventionally referred to as the angle, measured in degrees, of the direction of electrical current flowing through the ventricles. 7). 7 The range of angles of the QRS axis. below the line, the angle is expressed as a positive number; above the line, as a negative number.
