Tachycardia: Common Symptoms And Causes

March 2nd, 2010 | Under: Articles,Heart Diseases »

The term tachycardia derives from 2 Greek words: ‘tachys’ – rapid and the word ‘kardia’ – relating to the heart. To put it simple, tachycardia is an accelerated heart rhythm exceeding the resting rate of the heart rate in a person. It is a really severe condition that may become fatal if the heartbeat shoots up suddenly, provoking heart overworking, which can result in heart pumping not efficiently and supplying less blood to the body.

It may result in reduced oxygen flow to the heart, and this often has such consequences as angina, myocardial infarction, ischemic heart disease, as well as other heart disorders. Different tachycardia types and causes are described below.

Tachycardia types

  • Supraventricular tachycardia
  • Ventricular tachycardia
  • Sinus tachycardia

Causes of tachycardia

Heart Problems

Generally the most common causes of tachycardia are heart related disorders. Lots of heart diseases show tachycardia as the 1st sign that something is wrong.

Long-term hypertension is frequently implicated as the cause of tachycardia. It happens as the heart in patients with high BP is overworked for a long time. So if a person experiences stress, the heart cannot keep up with necessary oxygen amount, which results in tachycardia.

Heart valvular disorders can result in tachycardia too. It happens due to the fact that heart valves malfunction generally provokes blood leakage in the chambers of the heart. As a result abnormal pressure on ventricles takes place, and this might have unnatural reaction resulting in tachycardia.

Myocarditis also leads to tachycardia. Any kind of heart inflammation can be accompanied by tachycardia, together with such symptoms as difficulty breathing and chest pains.

Insufficient oxygen results in tachycardias. Heart muscles do not function in a proper way when they’re asphyxiated. In case of any heart disease myocardial infarction can eventually occur, and this can lead to tachycardia. Coronary heart disease is also known to cause tachycardia.

Lifestyle and diet

Unhealthy style of life and habits can be the cause of atrial tachycardia. A diet rich in cholesterol may result in atherosclerosis, a condition when fat depositions are present on the arteries’ inner walls, and this can lead to reduced flow of the blood to the heart. Alcohol and also caffeine abuse affects the heart and leads to tachycardia and then fibrillation. Stress is also an alarming cause of tachycardia noticed mostly in young adults. Medication abuse also results in tachycardia. The diet really rich or low in sodium may be the cause of tachycardia, as it results in the symptoms of electrolyte imbalance that frequently manifest tachycardia.
