When individuals have tachycardia, their heart beats too fast during resting periods. When either one or both of the chambers of the heart beat too quickly, its efficiency is compromised and the blood flow rate is decreased. This condition also causes the heart to demand more oxygen and if the oxygen requirement is not met, it can cause a heart attack.
Tachycardia can also cause individuals to have sudden cardiac arrest or a stroke. This disorder is often caused by medicine reactions, alcohol abuse and recreational drug use. Some people who have this disorder are born with heart irregularities that cause this condition to develop.
Individuals who have a fast beating heart may feel pains in their chest because there is not an adequate amount of blood flowing through the heart. People often feel confused, dizzy and lightheaded due to this condition. Heart palpitations are also common as well as being short of breath.
Individuals may become weak all at once and some people will faint. People who are at a higher risk of having tachycardia are those who are 60 years of age or older and have high blood pressure or heart disease. Individuals who experience anxiety and stress are also at a greater risk of having a rapid heartbeat.
The main goal of tachycardia treatment is to slow the beating of the heart and to keep this occurrence from happening in the future. Physicians may give the individual an injection so the heart will beat normally. Some people are prescribed anti-arrhythmic medications to take orally that keep the heart beating as it should. Medical professionals may shock the heart by using patches or paddles, when using cardioversion, if other types of treatment have failed. To keep subsequent episodes from happening, individuals may have an implantable cardioverter defibrillator placed inside their chest to track the rhythm of the heart.
