In the majority of cases, it is due to delayed conduction in the AV node, although conduction delay in the atrium, the His-Purkinje system or multiple sites may also contribute to the prolonged PR interval. 1.
WebbThe QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a significant finding. The reason for …
