  2. Heart rate: What's normal? - Mayo Clinic

    www.mayoclinic.org/healthy-lifestyle/fitness/expert-answers/heart-rate

    A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. To measure your heart rate, simply check your pulse.

  3. Pulse pressure: An indicator of heart health? - Mayo Clinic

    www.mayoclinic.org/.../expert-answers/pulse-pressure/faq-20058189

    The bottom number is called diastolic pressure. This is pressure in the arteries between heartbeats. The top number minus the bottom number is the pulse pressure. So if the resting blood pressure is 120/80 mm Hg, the pulse pressure is 40. This is considered a healthy pulse pressure. Generally, a pulse pressure greater than 40 mm Hg is unhealthy.

    A pulse is the heart rate. It's the number of times the heart beats in one minute. The pulse can be measured using the radial artery in the wrist or the carotid artery in the neck. Heart rates vary from person to person. Knowing your heart rate can help you gauge your heart health.

    Causes. Tachycardia is an increased heart rate for any reason. If a fast heart rate is caused by exercise or stress, it's called sinus tachycardia. Sinus tachycardia is a symptom, not a condition. Most heart conditions can lead to different forms of tachycardia. Irregular heart rhythms, called arrhythmias, are one cause.

    A normal heart rate range is 60 to 100 beats per minute. Your heart rate is a measure of how many times your heart beats per minute. It is also called your pulse.

  7. Blood pressure chart: What your reading means - Mayo Clinic

    www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/blood...

    This blood pressure chart can help you figure out if your blood pressure is at a healthy level. It also can help you understand if you need to take some steps to improve your numbers. Blood pressure is measured in millimeters of mercury (mm Hg). A blood pressure reading has two numbers. Top number, called systolic pressure.

  8. Low blood oxygen (hypoxemia) - Mayo Clinic

    www.mayoclinic.org/symptoms/hypoxemia/basics/definition/sym-20050930

    Most often, the amount of oxygen carried by red blood cells, called oxygen saturation, is measured first. It is measured with a medical device that clips to the finger, called a pulse oximeter. Healthy pulse oximeter values often range from 95% to 100%. Values under 90% are considered low. Often, hypoxemia treatment involves receiving extra oxygen.

  9. Heart arrhythmia - Symptoms and causes - Mayo Clinic

    www.mayoclinic.org/diseases-conditions/heart-arrhythmia/symptoms-causes/syc...

    A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. A heart arrhythmia occurs when the electrical signals that tell the heart to beat don't work properly. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be inconsistent. A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat.

  10. Heart palpitations - Symptoms & causes - Mayo Clinic

    www.mayoclinic.org/diseases-conditions/heart-palpitations/symptoms-causes/syc...

    Often the cause of heart palpitations can't be found. Common causes include: Strong emotional responses, such as stress, anxiety or panic attacks. Depression. Strenuous exercise. Stimulants, including caffeine, nicotine, cocaine, amphetamines, and cold and cough medications that contain pseudoephedrine. Fever.

  11. Bradycardia - Symptoms and causes - Mayo Clinic

    www.mayoclinic.org/diseases-conditions/bradycardia/symptoms-causes/syc-20355474

    Bradycardia (brad-e-KAHR-dee-uh) is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body.
