The transmission rate is greater, the case fatality rate is […]

The Multi-Ethnic Study of Atherosclerosis (MESA) found that a calcium […]
The Exercise Paradox: Sudden Cardiac Arrest in Athletes
The long term benefits of exercise are well documented, but as sports cardiologists we know that these benefits must be balanced against the short term risk of sudden cardiac arrest (SCA) from ventricular tachycardia (VT) and ventricular fibrillation (VF) occurring during or after exercise. The incidence of SCA is 1 in 50,000 among NCAA athletes, […]
Every breath you take: Measuring peak VO2

You can increase your peak VO2 through training, and it has been shown that high intensity training, or HIT, is the most effective way to do so. While […]
