Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

Soy oil increases heart rate variability

Taking daily supplements of fish or soy oil may improve cardiac function and protect against heart attacks in the short-term. Study results published in the April issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, are the first to show that soy oil increases heart rate variability (HRV), a measure of cardiac autonomic function.

High-rise homes have the highest levels of cockroach allergens

Roaches like to live high in the sky in places like Chicago, New York City and the Bronx, according to a recent study in the Journal of Allergy and Clinical Immunology. The study, conducted by an allergist affiliated with Children's Medical Center Dallas, found high-rise homes in Northeastern cities had the highest levels of cockroach allergens -- leading to a higher incidence of asthmatic episodes.

Mountaineering doctors hike medicine to new heights with Xtreme Everest

Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.

Study finds spikes in blood pressure, heart rate, adrenaline after 'dipping' snuff

After snuff use, heart rate increased by about 15 beats per minute (25 percent), systolic blood pressure went up by 12 mmHg (10 percent), and measurements of adrenalin in the bloodstream increased by more than 50 percent.
