Cardiologists explain how to lower resting heart rate, what a healthy heart rate is, and how to measure your own.
When is your heart rate normal and when is it dangerous? Experts explain what to do if your heart rate is too low or too high.
Sleeping on your side—period—is often recommended for heart health because it can help manage the potentially dangerous effects of sleep apnea. People with sleep apnea start and stop breathing ...
“Adopting a heart-healthy diet low in saturated fats, trans fats, sodium and refined sugars can significantly reduce the risk of heart attack.” Dr. Kohli echoes that advice.
Rate control lowers the heart rate closer to normal, usually 60 to 100 bpm, without trying to convert to a regular rhythm. Rhythm control tries to restore a normal heart rhythm in a process called cardioversion and maintains the normal rhythm with medications.
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures ), and add that amount to the diastolic pressure.
There are four primary vital signs: body temperature, blood pressure, pulse , and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR. However, depending on the clinical setting, the vital signs may include other measurements called the "fifth vital sign" or "sixth vital sign."
High blood pressure is caused by the force of blood flow in the arteries being too high. The DASH diet includes heart-healthy foods that lower blood pressure.
Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP).
A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.
