title: [From action potentials to ECG].
abstract: The gap between the action potentials of the myocyte and the ECG is now bridged by knowledge. The author demonstrates how learning the basics of ECG can be founded today upon cellular electrophysiology, thus exchanging the traditional "pattern recognition" training for reasoning. In the present article, this is applied to bundle branch blocks, atrial and ventricular hypertrophy, ischaemia and infarction. Further, the influence of drugs and electrolyte disturbances upon ECG is discussed. Basic knowledge of ECG is essential to avoid confusion when a commercial computer program for interpreting the ECG gives a wrong diagnosis.
