Explanatory. The doctor testified about Floyd’s heartbeat

George Floyd had “no pulse electrical activity”, his heart was not pounding when he arrived at a hospital in Minneapolis, the doctor testified on Monday.

Dr. Bradford Langenfeld was on duty at the Hennepin County Medical Center the night Floyd was arrested after police stopped arresting him last May, and testified at the trial of one of the officers on Monday.

Here is what Langenfeld saw – what it means.

WHAT IS THE ULTIMATE ELECTRICAL WORK?

This means that some weak or abnormal electrical activity may be detected on the heart monitor, but this is not enough to supply the heart with և blood և oxygen supply to the rest of the body.

WHAT The doctor saw elsewhere.

When Floyd arrived, he had no pulse and was in a cardiac arrest, which Langenfeld described as “the sudden cessation of blood flow to all tissues in the body when the heart stops pumping.” The doctor described that he was looking for possible explanations, and that hypoxia, or lack of oxygen, was one of the best possibilities.

Doctors measured the gases in Floyd’s blood and found that the carbon dioxide level was too high, again indicating a lack of oxygen.

WHAT treatments were given?

Floyd was given some medications that can sometimes help restore circulation, but it did not help. Defibrillators do not work in a situation like Floyd to get the heart back to normal. Langenfeld said an antidote to a drug like Narcan also does not help when someone has a heart attack.

WHEN DOES THE DOCTOR JOIN HIM?

Floyd had a cardiac arrest before he arrived at the hospital, and doctors worked on him about half an hour after his arrival. After his heart stopped working altogether. Langenfeld called it “flattery” and the doctor pronounced him dead.

The county medical investigator described Floyd’s death as a homicide, saying he died of “cardiovascular arrest, complicating law enforcement, restraint, and neck compression.”
