The beating of our heart can indicate our overall health. Resting heart rate is measured in a period of inactivity or during the sleep and in adults it usually ranges from 60 to 100 bpm (beats per minute). When the heart rate goes beyond 100bpm, doctors call this condition high resting heart rate or tachycardia.
Patients suffering from tachycardia often have other problems associated with their condition. Their heart is not efficient enough, so different organs and parts of the body may suffer from inadequate blood supply. Many of these people complain about: rapid pulse, breathing problems, chest pain and heart palpitations. Common problems are also lightheadedness, fainting and dizziness. Patients may notice one or more of these symptoms as the consequence of their high resting heart rate. In that case, consulting the doctor is always the best option.
Causes and Treatment of Tachycardia
Tachycardia is often caused by abnormalities in timing mechanism of electrical signals going through the heart or by some lifestyle factors of the specific patient. If this is something happening occasionally, it shouldn’t be reason to worry. However, consistent tachycardia is serious problem and consequences might be cardiac arrest, stroke or even death.
Congenital heart defects, heart disease, electrolyte imbalance, high blood pressure and hyperthyroidism are conditions often characterized by high resting heart rate. Apart from these, people who smoke and drink large quantities of alcohol and caffeine may also notice tachycardia as the consequence of their lifestyle. Consumption of different recreational drugs (cocaine or some other) may also lead to high resting heart rate. In some case, tachycardia may be provoked by medications or can be reaction to extreme stress and anxiety.
Pregnant women often have resting heart rate higher than normal. This problem is considered to be provoked by the fact that the body and the heart of a mother now need to support growing fetus. In pregnancy, doctors found resting heart rate about 85bpm to be normal. The problem arises if resting heart rate goes over 100bpm. If this condition becomes consistent this might indicate some medical condition that should be treated. For that reason, a woman experiencing palpitations (resting heart rate over 100bpm) should visit her gynecologist and consult him or her about the problem.
Tachycardia caused by lifestyle factors is usually corrected through healthy lifestyle changes. The person should quit smoking and limit consumption of alcohol and caffeine. Other than that, tachycardia is treated with medications and electroconversion methods.
