Quick pulse before workout… deadly?


A study recently published online in the European Heart Journal found a link between heart rate increase in anticipation of exercise and cardiac risk. The study found that individuals who experience mild mental stress in anticipation of a work out resulting in a quickened heart rate have twice the risk for sudden cardiac related death. Researchers commenting about the phenomenon stated, “Few measurements in medicine are as inexpensive and as easy to obtain in large general populations as to measure the heart rate difference between resting and being ready to perform an exercise test…” The researchers theorized that increased heart rate possibly serves as a modifier for risk causing ventricular fibrillation resulting in sudden death.
