2nd degree type I AV heart blocks are also sometimes called Mobitz type 1 or Wenckebach heart blocks.

With this type of heart block, one of the key characteristics that you'll notice is a gradual lengthening of the pr interval until a QRS complex suddenly disappears from the ECG strip. In other words, each P wave will be further away from the QRS complex until the QRS complex suddenly drops. The cycle will then repeat itself.
