What are tachycardia?
Normal heart function is essential for the overall health of each individual. Rapid heart rate or rapid heart rhythm, known as tachycardia, may indicate a heart problem or overall cardiovascular system. Tachycardia problems usually increase with the age of the individual. Symptomatic problems in addition to the rapid rhythm of the heart may include chest pain, dizziness and shortness of breath. The following commonly occur as tachycardia: damage to the heart or blood vessels, excessive thyroid or chemical stimulants.
heart disease is one of the leading causes of tachycardia. Caling of blood vessels that transmit blood from the heart - arteries - representing the predominant form of heart disease and subsequent symptoms of tachycardia. This hardening is often caused by long -term consumption of high -fat and cholesterol foods. As a result of hardening and possible blockage of artery, the heart must work harder and pump faster to supply blood into the body, thereby increasing heart rate.
Such conditions can also eventually damage heart muscles as well as infections or other underlying diseases. As a result, an individual who has suffered a heart attack often experiences serious heart damage. When the heart muscles are injured, they cannot function normally. The heart rate can therefore be accelerated or slowed.
different areas of the heart may have problems. Individuals who have to obtain pacemaker equipment to stimulate heart rhythm often develop disorders with a natural heart pulse generator: sinus node and sinus rhythm. Another area that can be affected by infection or other problems is SAC surrounding the heart: pericardium. When this protective coverage is inflamed, known as pericarditis, tachycardia is often the main symptom of the disease. Malformations in the heart chambers may also be present at birth, which makes it easier to eat a fast Heart rate. Low blood pressure may result fromany of these conditions, causing the heart to beat faster to maintain balance against blood pressure.
disorders from places other than in the heart can also indirectly affect the function of the heart and therefore become the main tachycardia. The thyroid gland is responsible for the regulation of most of the chemicals of the body, including those associated with the heart. As a result, excessive thyroid can affect all heart -related activities. Due to their close proximity to the heart, diseases affecting lungs can also affect the cardiovascular system. Stimulants such as caffeine, drugs or alcohol can also speed up the function of the body as well as anxiety or exercise.
One must consider changes in individuals' heart rate when discussing the causes of tachycardia. Normal degrees differ across populations and age groups and genetic differences can cause individual heart frequencies to take place in a wide range. Individuals can measure frequency by cataloging the number of heartrhythms in a wrist or neck during a minute period. Experts usually estimate the average resting heart rate anywhere between 60 and 90 rhythms per minute. Any permanent number above 100 - and more importantly, any number significantly different from the average of the individual - should be discussed with a doctor for driving tachycardia and to avoid complications such as stroke or cardiac arrest. Medicines or surgery may be necessary for more serious causes of tachycardia.
