- The pulmonary arteries are the only arteries in the body that carry de-oxygenated blood. Conversely, the pulmonary veins are the only veins in the body that carry oxygenated blood.
- The most common rhythm in sudden cardiac death (no pulse) is Ventricular Fibrillation. This rhythm is one in which all the foci in the heart are sending out impulses at the same time causing the heart to quiver like a seizure laden steak.
- Like most of the body, the heart does not receive blood flow when it contracts, called systole. The heart receives its blood flow when it relaxes, called diastole. This is why when someone has an extremely fast heart rate, like say 180+, the person could feel light headed due to the fact that their blood pressure will be low. This is because there isn’t enough time between contractions for the heart to receive enough oxygenated blood.
- A person can have a completely normal looking electrical rhythm on a monitor and still have no pulse and be declared dead. Known as pulseless electrical activity or PEA, it is treated, medically, the same as someone who has no electrical impulse, “flat-lined”.
- The terms “myocardial infarction” (or MI), “heart attack” and “cardiac arrest” are often used by lay people interchangeably. While a heart attack is indeed and MI, in truth, “cardiac arrest” simply implies the heart has completely stopped pumping blood. While there can be many different causes of cardiac arrest (i.e. auto-erotic asphyxiation carried on past the appropriate moment, or…let’s say for arguments sake, a lemming like need to keep up with Charlie Sheen on the weekends), an MI can lead to one’s ticker no longer ticking, which is bad; unless you really didn’t like the person, then it could be good. It’s all about looking on the bright side.
- The record for the most babies born to one woman is 69. While the woman’s name is not known, she was the first wife of Feodor Vassilyev a peasant from Shuya, Russia who lived from 1707-1782.
- Mary was the most popular female baby name in the US from 1879-1946. It was finally beat by “Linda” in 1947. Linda held that position until 1953 when it was beat out by none other than Mary, which then held that spot until 1962 when it was supplanted by “Lisa”. Since then, Mary has never regained the top spot. In the most recent complete year, 2010, Mary was the 109th most popular female baby name in the United States.
- Since “Lisa”, the most popular female baby names were: Jennifer, Ashley, Jessica, Emily, Emma, and Isabella, the latter of which has held the top spot since 2009. Isabella first debuted in the top 5 in 2006, appearing at position 4, and steadily climbed from there to number 1, no doubt initially spurred on by the 2005 release of “Twilight” with the main character being Isabella Swan.
