Some cases of tachycardia are mild and the person may not experience any symptoms, while other cases may be quite severe and life-threatening.
Tachycardia symptoms vary from person to person. Persons with mild cases may not experience any symptoms whatsoever. However, because the heart isn’t delivering blood properly, persons with this condition may experience symptoms such as chest pain or angina, heart palpitations, increased pulse, fainting, dizziness, low blood pressure, or shortness of breath.
Side effects and complications
Tachycardia can lead to some serious side effects, some of which are life-threatening. These include blood clots, stroke, sudden cardiac arrest or SCA, heart failure, fainting spells and even death.
Risk factors and other causes of tachycardia
Heart beat speed is regulated as the result of electrical impulses that tell it when to beat and how fast. For persons with tachycardia, these electrical impulses have been disrupted.
