Blood Pressure
Blood pressure explained - Better Health Channel
Blood pressure is the pressure of the blood in the arteries as the heart pumps it around the body. Blood pressure is not the same all the time; it changes to meet your body's needs. If blood pressure remains high, it can lead to serious problems...

Ms. Edna Parker- World's oldest known person turns 115 on Sunday
American Edna Parker, the world’s oldest known person, will celebrate her 115th birthday on Sunday, defying mind-boggling odds.
Her achievement was recognised by Guinness World Records last August after the death of a Japanese woman four months her senior.
There are only 75 people alive - 64 women and 11 men - that are 110 or older, according to the Gerontology Research Group, a California-based organisation that verifies reports of extreme ages.
Mrs Parker, who was born April 20, 1893, has been a widow since her husband Earl died of a heart attack in 1938.
She has also outlived her two sons - Clifford and Earl Jr - but is far from lonely with five grandchildren, 13 great-grandchildren and 13 great-great grandchildren to keep her company.
We don’t know why she’s lived so long,” said Don Parker, her 59-year-old grandson.
“But she’s never been a worrier and she’s always been a thin person, so maybe that has something to do with it.”
Scientists who study longevity hope that Mrs Parker can help unlock the secrets to long life.
Two years ago, researchers from the New England Centenarian Study at Boston University took a blood sample from Mrs Parker for the group’s DNA database of supercentenarians.
Her DNA is now preserved with samples of about 100 other people who reached the 110-year milestone, and whose genes are being analysed, said Dr Tom Perls, an aging specialist who directs the project.
“They’re really our best bet for finding the elusive Holy Grail of our field - which are these longevity-enabling genes,” he said.
On Friday, a birthday party for Mrs Parker was held at her nursing home in Shelbyville, Indiana.
A smiling Mrs Parker looked on as relatives and guests released 115 balloons into the sky to celebrate her milestone.

Unwavering Hope
It was a trauma at the end knowing that two parents suffered so much anguish and sadness. Five weeks, the Van Ryn family did all they can do to stay wide-awake if possible with the thought that one day Laura their daughter would wake up from coma!
It was Whitney Cerak who was in the hospital bed that survived from the car accident and Laura Van Ryn has died!
May The Good Lord bless these families and I hope they will have peace of mind later after two years had passed. Also, may God bless Laura Van Ryn soul and rest in peace.
What a tragic incident! I cried!

ICD Implantation
ICD Implantation
The implantable cardioverter defibrillator (ICD) is a device used to treat dangerously fast heart rates that occur in the lower chambers of the heart (the main pumping chambers). The ICD system looks much like a pacemaker. The device is implanted under the skin and attached to one or more leads, which are placed in or on the heart muscle.
Illustration: ICD implantation. Image of implantable cardioverter defibrillator (ICD) implanted in heart. The implantable cardioverter defibrillator (ICD) detects arrhythmias (both bradyarrhythmia and tachyarrhythmia) and delivers electrical therapy (pacing pulses or defibrillation therapy) as necessary. When not needed, the ICD merely monitors the heart without delivering any electrical energy. Click on the heart to see an enlarged view.
