Blood Pressure (Definition)
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more

How does high blood pressure affect your heart?
Requires both muscle: to work harder to drive blood forward & ?es valve leaflet loads to block reverse blood flow. Heart muscle requires more blood flow for more work (more susceptible to damage of artery Ds), muscle gets thicker/stronger but also stiffer (no longer allows blood return from veins at low pressure) over time. Both lead to ?ed heart attack rates, enlargement, congestive failure, atrial fibrillation, etc. ...Read more

How does dehydration decrease blood pressure and increase heart rate?
The decrease: In BP is due to the decline in plasma volume. The increase in hr is compensatory to meet the body's needs in this state. ...Read more

How can smoking and high blood pressure affect the heart?
Hypertension: Both smoking and hypertension cause coronary artery disease and increased cardiac stress. If you smoke and have hypertension, there's a good chance you'll get first hand experience of the bad effects. ...Read more

How quickly does high blood pressure damage the brain and heart?
A long time: Hbp causes its damage over many years - decades. (exception: super high blood pressure, in the range of 220/120 or higher, can cause immediate damage which is reversible. Symptoms are: confusion, heart failure, angina). ...Read more

How can exercise intensity affect heart rate and blood pressure?
Exercise: Higher intensity yields higher heart rates and bp. ...Read more

How does atrial and ventricular tachycardia affect blood pressure and cardiac output?
Different arrythmias: They come from different chamber ( upper vs lower) . Changes in BP and cardiac output depend on cardiac function , heart rate and and timing. Atrial fibrilation may decrease cardiac output about 15%. In ventricular tachycardia, BP and co will decrease more if it is long enough to become unstable. ...Read more

What are hypoglycemia's effects on heart rate and blood pressure?
Hypoglycemia: Low blood sugar may cause palpitations or fast heart rate, and causes a weak, shaky feeling. Blood pressure may go up (due to heart working harder with stress) or down (due to overall weakness effect) or remain normal. If someone feels like sugar is low and unable to test right away, it's safe to eat/drink extra to bring sugar up than to wait and risk passing out, etc. ...Read more

Does high blood sugar cause your heart rate to be low?
Usually it's fast: Usually, if it would cause anything it would be fast heart beat, if very high and associated with diabetic ketoacidosis (dka), but if it's severe, especially at the level of hyperosmolar hyperglycemic syndrome (hhs) then it can be associated with slow heart beat - but then you'd be severely ill with a reduced level of consciousness. ...Read more

How can high blood cholesterol affect the heart?
High CHOL : Specially high LDL and low hdl, may accumulate through a complex process of injury at the endothelium. Inner part of the coronary artery. That accumulation it's call the atheromatous plague. Also compose of other inflammatory cells. That formation may grow and occlude the artery increasing risk of heart attack. ...Read more

How can I increase blood pressure and pulse fast?
Exercise.: Stand up and run. Get scared. Hurt yourself. All of these will increase hormones which raise hr and bp. ...Read more

How fast does high blood pressure damage the brain?
Depends on rate: If you have a sudden surge of pressure and a weakened artery in the bran it can have devastating results. If the pressure is elevated long term there are several mechanisms that occur to protect the brain. However anytime the diastolic BP is above 110 ( the lower #) the risk of stroke goes up ...Read more

Why do I experience a low heart rate with normal/high blood pressure and a high heart rate with low blood pressure? Thanks
No Easy Answers from: A distance. Everything you describe is a behavior/sign/symptom, none causal. Heart rate, strength of contraction (both heart functions) ; BP (mean arteriole resistance) are all controlled 24/7, split-second by split-second, by our brain/mind at below conscious, autonomic nervous system level. While alterations in heart muscle size & function (usual doc focus) are also a factor, these are secondary ...Read more

How does exercise help reduce high blood pressure and heart disease?
Decrease risk: Aerobic exercise will make your heart stronger. If your heart can pump blood with less effort then the force at the arteries will decrease and the arteries will relax, decreasing your bp. Control BP will decrease the risk of heart attack and stroke. Plus exercise will control your weight, help with high bad cholesterol and decrease stress in your life, all risk factors for heart disease. ...Read more

Could you tell me what are hyperglycemia and hypoglycemia's effects on heart rate and blood pressure?
Increasing : Hypoglymia will trigger a sympathetic response increasing hr and bp. During hyperglycemia, if you are diabetic, the response will be lighter or none, depending in complications associated like hyperoamolar state and ketoacidosis, when the response will be stronger. ...Read more

What can cause a fast heart rate, high blood pressure especially diastolic and nervousness?
Many things: This can be either due to heart or non-heart reasons. Of heart causes, would consider a tachyarrhythmia (e.g. Svt, atrial fibrillation, atrial flutter) - would need an event monitor to check this. Also consider some other causes (not a comprehensive list due to space limitations for answers, but more commonly tested): hyperthyroidism, anemia, illness, pheochromocytoma, or panic/anxiety attack, . ...Read more
