The red circle left behind by ECG generally does not need to be treated, and will disappear on its own in 1~3 days, if it does not subside for a long time, it needs to be examined to clarify whether there is a blood disease.
1. No treatment needed: the red circle left by ECG is caused by the negative pressure in the suction ball used to fix the lead placed on the chest, which sucks the skin and leads to capillary congestion or rupture and bleeding, and it will disappear by itself after 1~3 days, so no treatment is needed.
2. Long-term failure to subside: If the red circle does not subside for a long time, it is necessary to consider whether there is a coagulation dysfunction, whether there is hemophilia and other blood diseases, so it is necessary to carry out blood routine, coagulation function and other tests to further assist in the diagnosis.
It is recommended that patients continue to observe the disappearance of the red circle, if there is any abnormality, they should consult the doctor in time.
