It covers what is normal, what large studies found about a slow heart rate, why trained people often sit so low and which signs mean you should call your GP. That matters, because the same number can be ordinary for one person and a reason to get it checked for another. The difference usually lies in symptoms and in what else is going on, such as medicines that slow the heart.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a>,<a href=\"#bronnen\">1<\/a><\/sup> <a href=\"https:\/\/bioprofile.com\/en\/heart-self-test\/\">The BioProfile heart and vascular scan<\/a> gives you an indication of where you stand in this area today.

In wearable device data from 92,457 adults in the United States, collected over two years, the average daily resting heart rate was 65 beats per minute, but personal averages ranged from 40 to 109.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">4<\/a><\/sup> Most people stayed fairly stable, and about one in five had at least one week in which their resting heart rate varied by 10 beats or more.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">4<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Put simply: a resting pulse somewhere in the 40s is below the rule of thumb, but it falls within the range of personal averages in this study, which does not show how often a heart rate of around 44 occurs. Your own baseline is the better measure. The researchers reached the same conclusion: everyone has their own resting heart rate, and it can differ a lot from someone else&#8217;s.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">4<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Dutch study points the same way for the electrical recording of the heart, the ECG. The study set out normal ECG values for each age group, using 13,354 people aged 16 to 90 with a healthy heart from four Dutch population studies, and most values differed between women and men.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">5<\/a><\/sup> So a single number for everyone is only a rough guide. You will find the usual values for each age on our page about <a href=\"https:\/\/bioprofile.com\/en\/normal-heart-rate\/\">a normal heart rate<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"is-hartslag-44-te-laag-wat-grote-studies-vonden\">Is a heart rate of 44 too low? What large studies found<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The clearest answer comes from the Multi-Ethnic Study of Atherosclerosis in the United States, which followed 6,733 people aged 45 to 84 who had no cardiovascular disease at the start for 10 years. A heart rate below 50 was not linked to more cardiovascular disease, whether or not people took medicines that affect the heart rate.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup> In people who did not take such medicines, a heart rate below 50 was not linked to a higher risk of death either. In people who did take such medicines, a heart rate below 50 came with a clearly higher risk of death, more than two times as high.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What this means: in this group, a slow heart rate with no symptoms and no medicines that slow the heart was not linked to extra risk over ten years. That does not prove a heart rate of 44 is harmless for everyone who feels well. If you take a medicine that slows the heart, talk to your doctor about a very low number.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A larger share of the research looks at the other end of the scale. A meta-analysis of 46 studies, covering more than 1.2 million people from the general population, found that every 10 extra beats per minute at rest came with a slightly higher risk of dying, from any cause and from heart and vascular disease. Above 80 beats per minute, the risk was clearly raised.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">6<\/a><\/sup> Put simply: across the whole population, the worrying signal in these figures comes from a high resting pulse more than from a low one.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">6<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"waarom-getrainde-mensen-vaak-lager-zitten\">Why trained people often sit lower<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In athletes, a slow heart rhythm between 30 and 60 beats per minute is described as a normal adaptation of the body to regular, intensive training.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> It is common. Studies report it in 98 per cent of elite professional cyclists and in half of male footballers.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> So if you train hard and often, a resting pulse of 44 can simply be a sign of that training.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> You can read what too little exercise does to your body in <a href=\"https:\/\/bioprofile.com\/en\/effects-of-too-little-movement-what-it-does-to-your-body\/\">what too little exercise does to your body<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wanneer-een-aandoening-de-oorzaak-is-van-een-trage-hartslag\">When a condition is the cause of a slow heart rate<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A slow heart rate can also be caused by a problem in the heart rhythm itself. Sick sinus syndrome is one such rhythm disorder, and the researchers describe it as a common reason for a pacemaker.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">7<\/a><\/sup> Two population studies in the United States followed 19,893 people aged 45 and over for an average of 17 years. None of them had a pacemaker or atrial fibrillation at the start, and 213 participants developed sick sinus syndrome, so it is uncommon.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">7<\/a><\/sup> After adjusting for other factors, people who developed the syndrome were nearly three times as likely to develop heart failure, and the syndrome was strongly linked to getting a pacemaker. Their higher risk of death disappeared once cardiovascular disease that developed during the study was also taken into account.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">7<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Put simply: sick sinus syndrome is uncommon, and it is serious when it does occur.

The same applies if you feel confused, have trouble speaking, see differently or have a drooping face, and if you feel restless, sick, sweaty or look pale.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">3<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have fainted, call straight away if you had chest pain or that feeling of palpitations just before, if your arms and legs jerked for a while, if you were unconscious for more than 3 minutes, or if you were confused for 5 minutes or longer after coming round.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">8<\/a><\/sup> Make an appointment with your GP on a working day if you fainted without feeling it coming, if you have fainted more than once, if you are older than 70, if you take medicines that lower your blood pressure, or if family members under 40 have heart problems or have died suddenly of a heart problem.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">8<\/a><\/sup> In most cases, fainting is harmless and is caused by your blood pressure dropping for a moment.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">8<\/a><\/sup> You can read which heart symptoms women may notice in <a href=\"https:\/\/bioprofile.com\/en\/heart-complaints-women-symptoms\/\">heart symptoms in women<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Put simply: in the large study, a low number without symptoms and without medicines that slow the heart was not linked to extra risk.
