What primary event has occurred when a client experiences an ectopic focus?
Andreyy89
Ectopic focus or ectopic pacemaker happens when an excitable group of cells outside the normal sinoatrial node causes premature heartbeat. Sinoatrial node (SA node) is the pacemaker of the heart. Most people experience ectopic focus but persistent occurrence may need the client/patient to visit the doctor. If a client or patient complains of ectopic focus, it is better to consider his/her activity before visiting the clinic. Ask, for example if the client/patient had a vigorous exercise because it might be causing the irregular heartbeat, how often is he/she experiences such irregularity in his/her heartbeat (acute ectopic foci is usually non-life threatening, however, chronic type requires medical help), his/her lifestyle (he/she might be using illegal drugs, smokes and/or drinks alcohol,had too much coffee etc). Again, history taking is very vital.

Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.

But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.
