What are the common causes of low heart rate?
Bradycardia is a condition that is commonly known as low heart rate. Normal heart rate at a rest adult is considered 60 to 100 rhythms per minute. Any heart rate below this is considered low. Sometimes this condition is caused by a health problem, especially a heart problem or medication. Other times it may not be a problem at all, just a sign of good health. For example, a heart attack or other trauma into the heart can cause problems in the natural cardiosterimulator of the heart. This may sometimes cause a person's heart to beat too quickly or too slowly.
Many times patients with this type of problem have an artificial pacemaker. These small electronic devices are often surgically implanted in the chest. This device is then connected to the heart and electrical impulses cause the heart to beat in a regular rhythm. The problems can also suffer from low heart rate. For example, hypothyroidism occurs when the thyroid gland produces insufficient amount of thyroxine.This is a hormone responsible for regulating the metabolic measure of a person. Low levels of this hormone can cause low heart rate.
Chemical imbalance, such as electrolyte imbalance, can also cause the heart to beat too slowly in the human body. Hyperkalaemia occurs when blood has too much potassium. This can cause the muscles in the heart to stop functioning properly, which can lead to low heart rate and in some cases heart failure. The massive dose of potassium is injected into prisoners convicted of deadly injections.
low heart rate may also be a side effect of some drugs. It is irony that most of the drugs that can do this side effect are the same healing used to treat other heart problems. For example, beta-blockers are used to treat high blood pressure, but some individuals may also cause dangerously low heartsFrequency.
In some individuals, low heart rate is actually a sign of good health and fitness. People who practice regularly, including trained athletes, usually have a lower heart rate than more sedentary individuals. This happens because active individuals usually have a much healthier heart.
A person who has a low heart rate should usually only worry if he experiences negative symptoms. Some signs of health problems on slow heart rate include dizziness and fainting, along with weakness, fatigue and chest pain.
