Heart arrhythmias give a runner pause
March 2015, Tallahassee Democrat
I remember an argument that went something like this — we all have only so many beats in our hearts and when the last one gets used, well that is it. And exercise? Well, it makes your heart beat faster so stay away from it. Of course if you understand the math of a healthy heart you know a fit heart will, over the course of a life, beat far fewer times (all other things being equal) than a heart that receives no exercise benefits. (Check out the calculator at http://www.csgnetwork.com/avglifeexpfromhr.html.) (72-68; 49-100.7)
However, within the general rule, there are things that make us think hard. One of those topics is the interaction between arrhythmias and exercise. Learn More.

Nervous system disorders not diagnosed properly
February 2015, The Hindu
The first Indian to deliver the T.S. Srinivasan Endowment Oration on Saturday, Christopher J. Mathias, focused on the challenges of autonomic dysfunction, and traced the formation, development and growth of autonomic medicine over the last four decades....
The autonomic nervous system is responsible for organ function and key activities such as the control of blood pressure, heart rate and body temperature.

Falling into a dead faint
January 2015, The Nation - Health Matters
Fainting or swooning was so common in Victorian England that the houses of the upper classes even had a fainting room where ailing ladies - never men - could lie down on a special couch and be treated with smelling salts until they recovered. While one theory has it that either overly tight corsets or hysteria were to blame, the fact is that even in today's corsetless society, women - and yes, men too - can and occasionally do pass out.

Syncopal Episodes Can Warn of Cardiac Conditions
January 2015, JEMS.com Journal of Emergency Medical Services
...Why did a healthy, young adult male pass out, and is there any correlation between Mark’s syncopal episode and the untimely death of his uncle? When EMS is evaluating a patient who has experienced a syncopal episode, they should attempt to identify a cause. Commonly, syncope is caused by a transient loss of blood supply to the brain, which can be due to dehydration, blood loss, cardiac dysrhythmias or neurologic events such as transient ischemic attacks. The fact the patient is young and healthy doesn’t negate the fact something caused him to lose consciousness. Learn more.

Despite having an autonomic disorder, teen stays active
November 2014, Visalia Times-Delta
Taylor Stainbrook gets clammy, weak and white-sheet pale before she can pass out.
An episode can last a few minutes to a few hours. For an active 16-year-old athlete, that can seem like an eternity. During her sophomore year, she missed 56 days of school at Golden West High School where she's played on the varsity volleyball team since she was a freshman.
During a volleyball game, she normally plays the whole game.
"I feel better if I don't stop," she said.
She suffers from an autonomic disorder for which there is no cure but, with any luck, she may outgrow it in two to five years. Not a lot is known about Postural Orthostatic Tachycardia Syndrome or, simply, POTS. It effects her digestion as well as her heart rate and blood pressure. Learn More.
