What does it mean to have a widening pulse pressure?
Widened pulse pressure may increase the risk of heart attacks and cardiovascular disease. Pulse pressure is the difference between your two blood pressure readings – systolic and diastolic.
Cushing's triad of signs includes hypertension, bradycardia and apnea. Cushing recognized that the body's initial response to rising intracranial pressure is a rise in systolic blood pressure. The rising systolic pressure results in widened pulse pressures, bradycardia and irregular breathing.
Cushing's triad is a clinical triad variably defined as having: Irregular, decreased respirations (caused by impaired brainstem function) Bradycardia. Systolic hypertension (widening pulse pressure)
A bounding pulse is a pulse that feels as though your heart is pounding or racing. Your pulse will probably feel strong and powerful if you have a bounding pulse. Your doctor might refer to your bounding pulse as heart palpitations, which is a term used to describe abnormal fluttering or pounding of the heart.
It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole. For example, with a blood pressure of 120/80 ("120 over 80"), the systolic pressure is 120. By "120" is meant 120 mm Hg (millimeters of mercury).
The second number, called diastolic blood pressure, measures the pressure in your blood vessels when your heart rests between beats. If the measurement reads 120 systolic and 80 diastolic, you would say “120 over 80” or write “120/80 mmHg.” The chart below shows normal, at-risk, and high blood pressure levels.
Cardiac output is the product of two variables, stroke volume and heart beat. Heartbeat is simply a count of the number of times a heart beats per minute. Stroke volume is the amount of blood circulated by the heart with each beat. The formula for this is expressed as CO = SV x HR.
For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the person's physical condition and age. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA.
Blood pressure is measured with an instrument called a sphygmomanometer. Blood pressure is measured in millimeters of mercury (mm Hg) and recorded with the systolic number first, followed by the diastolic number. For example, a normal blood pressure would be recorded as something under 120/80 mm Hg.
Follow a healthy lifestyle to keep it at this level. More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it. Make healthy changes to your lifestyle.
Pulse pressure is the difference between the systolic and diastolic blood pressure. It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. For example, if resting blood pressure is 120/80 mm Hg, then the pulse pressure is 40 mmHg.
The heart rate is the number of times the heart beats in the space of a minute. The pulse rate is exactly equal to the heartbeat, as the contractions of the heart cause the increases in blood pressure in the arteries that lead to a noticeable pulse. Taking the pulse is, therefore, a direct measure of heart rate.
The heart is a muscular pump that with each heart beat pumps blood around the body. On leaving the heart the blood first travels along the arteries. The pulse is what you feel over an artery as the pressure inside increases following each heart beat. The average pulse rate is between 60-80 beats per minute.
Optimal blood pressure typically is defined as 120 mm Hg systolic — which is the pressure as your heart beats — over 80 mm Hg diastolic — which is the pressure as your heart relaxes. For your resting heart rate, the target is between 60 and 100 beats per minute (bpm).
A normal resting heart rate for adults ranges from 60 to 100 beats a 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 a minute.
Conditions that can slow electrical impulses through the heart. Examples include having a low thyroid level (hypothyroidism ) or an electrolyte imbalance , such as too much potassium in the blood. Some medicines for treating heart problems or high blood pressure, such as beta-blockers , antiarrhythmics , and digoxin.
If you have bradycardia, your brain and other organs might not get enough oxygen, possibly causing these symptoms:
- Near-fainting or fainting (syncope)
- Dizziness or lightheadedness.
- Shortness of breath.
- Chest pains.
- Confusion or memory problems.
- Easily tiring during physical activity.
A heart rate of less than 60 beats per minute (BPM) in adults is called bradycardia. What's too slow for you may depend on your age and physical condition. Physically active adults (and athletes) often have a resting heart rate slower than 60 BPM but it doesn't cause problems and is normal for them.
Having bradycardia (say "bray-dee-KAR-dee-uh") means that your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy.
