It is the classical description of wenkebach AV block type 1 there is progressive prolongation of PR interval followed by a blocked p wave and hence a dropped qrs complex. The usual conduction ratio for wenkebach AV block is 3:2 or 4:3 .
It is well known wenkebach AV block is usually a benign form of AV conduction defect and it [...]

They damage the vascular endothelium either directly or indirectly ,   by aggravating the atheroscelortic process .  Diabetes apart from affecting the medium sized arteries , also affect the microvasculature.  Smoking  has a direct effect on endothelial function .It depletes vascular nitric [...]
