Low Heart Rate Causes Bradycardia can be caused by many conditions. Some of the most common causes include: Not getting enough electrolytes in your diet, especially calcium, magnesium, and potassium Anorexia nervosa, an eating disorder Inflammation in your heart (myocarditis), the inner lining of ...

Normal people experience ups and downs in these readings over the course of a day. Onehigh blood pressurereading does not always indicate that an individual suffers from a disease. A doctor may take readings over time to make an accurate diagnosis. If your first reading is high, you might b...
A heart rate that is either consistently too high or too low may be an indication of a medical problem. A condition calledtachycardiaoccurs in persons with a heart rate of more than 100 BPM, whereas a condition calledbradycardiaoccurs in persons with a heart rate of less than 60 BPM.Symptom...
Is it better to have a high HRV or a low HRV? Observational studies have shown that a low heart rate variability is associated with an increased risk of diabetes, high blood pressure (hypertension), and cardiovascular disease (CVD). While that doesn’t mean that a low HRV causes these iss...
is no direct correlation between blood pressure and heart rate, so having high blood pressure, orhypertension, does not necessarily result in having a high pulse rate, and vice versa. Heart rate goes up during strenuous activity, but a vigorous workout may only modestly increase blood pressure....
124,125 Blood pressure also follows an endogenous circadian rhythm that peaks around 9:00 p.m. in humans.126 Light can also directly impact heart rate such that light in the middle of the night and particularly in the early morning, when heart rate is low, induces an increase in heart ...
