The way that even low levels of carbon monoxide can be fatal, by disrupting the heart's rhythm, has been unravelled by researchers in Leeds. They found that levels common in heavy traffic could affect the way the heart resets itself after every beat.
Their study in the American Journal of Respiratory and Critical Care Medicine showed a common angina drug may reverse the effect. The British Heart Foundation said the research was a promising start.
Carbon monoxide is produced by faulty boilers, cigarettes and car exhausts. Symptoms of carbon monoxide poisoning:
- Loss of consciousness
The University of Leeds research team found that the gas kept sodium channels, which are important for controlling the heartbeat, open for longer. Disrupting the sodium channels can disrupt the heart's rhythm, leading to cardiac arrhythmia, which can be fatal.
CO2 IS HARMLESS TO HUMANS AND GOOD FOR PLANTS.
CO IS TOXIC.
WE NEED TO GET THE LEFTISTS OFF THEIR CO2PHOBIA AND WE NEED TO DESIGN AND MARKET CATALYTIC CONVERTERS THAT TURN CO INTO CO2.
