Abstract

The abbreviation “EKG” comes from the German word “elektrokardiogramm”, the name given to this record by Dr. Willem Einthoven, the Dutch physician who invented the string galvanometer and this type of electrical record of the heartbeat. It consists of P, Q, R, S, T, and U waves. The P wave is associated with depolarization of the atria, after which they contract. The normal P wave duration is up to 0.12 seconds.
