Introduction to ECG interpretation

Cardiac electrophysiology: action potential, automaticity and vectors

Cardiac electrophysiology: membrane potential, action potential, automaticity and electrical vectors   Video lecture The following video lecture summarises this chapter.   The action potential includes a depolarization (activation) followed by a repolarization (recovery). The action potential occurs in all cardiac cells but its appearance varies depending on cell type. During de- and repolarization ions (Na+ [sodium],…


Clinical electrocardiography and ECG interpretation

Principles of cardiac electrophysiology and ECG interpretation For the heart to work effectively, the atria and the ventricles must be activated rapidly and sequentially. Rapid activation is important in order to activate as much myocardium simultaneously as possible; the more myocardium contracting at the same time the more efficient the pumping mechanism. Sequential activation implies that the…


How to interpret the ECG / EKG: A systematic approach

Systematic approach to ECG interpretation: efficient and safe method The ECG must always be interpreted systematically. Failure to perform a systematic interpretation of the ECG may be detrimental. The interpretation algorithm presented below is easy to follow and it can be carried out by anyone. The reader will gradually notice that ECG interpretation is markedly facilitated by…
