How Does Acidosis Affect The Heart?

Share on facebook

In this video we look at what is a healthy heart rate, what affects heart rate, and how to take your pulse. We also look at normal heart rate as well as exercise and heart rate. Transcript notes What is heart rate? What is a healthy heart rate? What is a normal resting heart rate? Heart rate is the number of times your heart beats in a minute. It is measured in bpm or beats per minute. A healthy, Normal resting heart rate is usually between 60 and 80 beats per minute. The resting heart rate of a woman is usually about 10 beats more per minute than that of a man in the same age range, and elite athletes can have a resting heart rate near 40 beats per minute. This is because Individuals that are fit have a larger stroke volume of the heart. Stoke volume is the amount of blood ejected from the heart per beat. So, the heart of someone who is really fit does not need to beat as many times to have the same output of blood as an unfit person. Another thing that has a major effect on heart rate is stress. During stressful situations the body releases the hormone adrenaline which causes an increase in heart rate, which is beneficial when you are in danger, but unhealthy in everyday situatio

Re: Does Blood Ph Affect Heart Rate, And, If So, How?

Re: Does blood pH affect heart rate, and, if so, how? Posted By: Amit Agarwal, Grad student, Neuroscience/Neurogenetics, Dear Casey, Its indeed an interesting question, which still keeps manyscientific minds busy. Many researchers working in the field of cardiacbiology are trying to understand detailed electrophysiological andneurochemical mechanisms which can affect heart rate and its efficiency.There are several studies available on rodents which outline factorsresponsible for the maintenance of normal heart rate. Your question alsotargets one of the aspects of such studies. Several studies have shown thatacidosis can lead to reduced heart rate. So before going ahead letsunderstand what is acidosis? When breathing is restricted, the body cannot eliminate carbon dioxide asit should, and the amount of carbon dioxide in the blood increases. Carbondioxide (CO2) and water (H2O) exist in equilibrium with carbonic acid(H2CO3) in a reaction catalyzed by an enzyme called carbonic anhydrase.CO2 + H2O --> H2CO3 A molecule of carbonic acid dissociates on its own into a moleculebicarbonate (HCO3-) and an (acidic) hydrogen ion. (H+) H2CO3 <> HCO3- and H+ Thus the overall pattern is: H2O + CO2 Continue reading >>

    Thanks for posting, Brenda. Very informative...
    Here's an excerpt:
    "It’s important to understand that neither nitrate nor nitrite accumulate in body. Ingested nitrate from food is converted into nitrite when it contacts our saliva, and of the nitrate we eat, 25% is converted into salivary nitrite, 20% converted into nitrite, and the rest is excreted in the urine within 5 hours of ingestion. (3) Any nitrate that is absorbed has a very short half-life, disappearing from our blood in under five minutes. (4) Some nitrite in our stomach reacts with gastric contents, forming nitric oxide which may have many beneficial effects. "

Acidosis And Contractility

how does acidosis cause reduced contractility? how does acidosis cause reduced contractility? If you are acidotic then H+ is going to be coming into the cell from the extracellular space which will cause K+ to efflux out. In heart tissue this means that K+ will be leaving the cell causing the resting membrane potential to become more negative and thus less excitable. thanks you guys that makes perfect sense!! I think (in addition to the HyperK+) the H+ ions also protonate and inactivate Na Channels. The idea that acidosis (i.e. incr [H+]) leads to efflux of K+ from cardiac myocytes --> hyperpolarization and thus decreased contractility makes sense, but is there such thing as a H+/K+ exchanger on such cell types? I've looked in BRS Physiology, but can't find one. There is a Na+/H+ exchanger, but that's different. Plus, this article states that "the dominant mechanism for the reduction of contractility in whole tissue is competitive inhibition of the slow calcium current by hydrogen ions." I know this is an old thread, but would anyone care to shed some light on this issue? Thanks! There are some other conjectures which can be found here . I always thought that the effects of acidos Continue reading >>

    I won't blame it on the Margarita at Margaritaville or the few slips up while at IOA........I will blame it on the Dimatap, NyQuil and Robitussin!! LOL!!
    I have had this awful cough/cold for a week now (I know, I should go to the DR.!! LOL) and having been taking all the above medicines!! I am feeling better ( a little) but was wondering if anyone knew of Lo Carb cough/cold medicines for the future.
    Back to induction for me!!
    I did step on the scale and I am down 10 lbs. (although my scale is not the most accurate).
    Thanks

    Could you use the Nyquil gel caps? Those seem alright for my dh, don't knock him out of ketosis. Robitussin makes a sugar free cough syrup and sugar free cough drops.
    Sometimes we just have to suffer the loss of ketosis to feel better. You'll get right back into ketosis when you are well, it will only take a couple of days.
    I'm off to search the web now and look for low carbohydrate cold remedies.
    {{{HUGS}}} sweetie, hope you are feeling better very soon.

    Don't feel too bad. I'm on a presciption cough syrup that tastes sooo sweet must be full of sugar. I have Bronchitis and its the only way I can stop coughing. I'm not even going to worry about it though, because my appetite is not what it should be...I haven't really been eating normally.

How Acidity Interferes With The Heart Beat

How acidity interferes with the heart beat How acidity interferes with the heart beat Modulation of hERG potassium channel function by extracellular acidosis: single channel effects and underlying basis Start date: 16 December 2013 (Duration 3 years) The hearts ability to pump blood round the body depends on co-ordinated electrical activity generated by small proteins in heart cells called ion channels. When blood flow to the heart is blocked off, for example, because of coronary heart disease or a heart attack, the blood becomes acidic. This acidity alters cardiac ion channel function and can predispose the heart to develop an irregular heartbeat or arrhythmia. An ion channel called hERG is central to normal cardiac activity. There is evidence that acidity (acidosis) impairs hERG function in ways that increase arrhythmia risk but the underlying mechanisms are incompletely understood. This project aims to provide, for the first time, detailed insight into how acidosis alters the electrical activity of individual hERG channel proteins. Genetic methods will be used to investigate which parts of the ion channel protein are affected by acidosis to modify hERG function. The results of Continue reading >>
