Low heart rate:
Symptoms of low heart rate:
Each heart has it own normal rhythm brought about by the seamless flow of electrical impulses that begins in the heart's natural "pacemaker" sinus node. The electricity flows through the upper chambers (atria), crosses the bridge between upper and lower chambers atrioventricular node and travels to the lower chambers ventricles. This passage of electricity culminates in a carefully coordinated contraction of heart muscle that pushes blood throughout the human body.
Each day, a normal heart contracts about 100,000 times, at a rate anywhere from 60 to 100 times a minute. Abnormally slow heart rates are typically those below 60 beats a minute and either can be relatively harmless or life threatening. Changes in rate brought about by variations in activity, diet, medication and age are normal and common. For some people, such as athletes in top condition, a resting heart rate of below 60 can be normal. Similarly, at certain times, such as sleep, a heart rate may slow and still be normal. Symptoms of low heart rate are:
Shortness of breath.
