Tachycardia is a rapid heart rate of more than 100 beats per minute. Sinus tachycardia, from the heart's sinus node, is a normal response to exercise, illness, or stress.
There are several types of abnormal tachycardias or arrhythmias . These can come from two places:
Atria (the two smaller chambers on the top of the heart)—called supraventricular tachycardias
Ventricles (the lower chambers of the heart)—called ventricular tachycardia
These factors increase your chance of having tachycardia. Tell your doctor if you have any of the following:
Heart disease, especially a prior heart attack
Cardiomyopathy —damage to the muscle wall of the lower chambers of the heart
Electrolyte abnormalities—too much or too little calcium, sodium, magnesium, and potassium in the blood
Myocardial ischemia—insufficient blood flow to heart muscle tissue
Hypoxemia—not enough oxygen in the blood
Acidosis—too much acid in the body’s fluids
Symptoms include:
Heart palpitations
Fast heart rate
Dizziness
Lightheadedness
Fainting or near fainting
Chest pain
Shortness of breath
Diagnosis
Your doctor will ask about your symptoms and medical history. You will also have an exam. Tests may include the following:
Electrocardiogram (ECG, EKG) —a test that records the heart’s activity by measuring electrical currents through the heart muscle
Holter monitor or event monitor —an ambulatory monitor to record your heart rhythm that can be worn from 1-30 days to detect arrhythmias and correlate symptoms with the heart rhythm
Exercise test —particularly if the symptoms occur during physical activity
Electrophysiology study —an invasive test where monitoring wires are placed inside the heart and the heart's conduction system is tested directly
Cardiac catheterization —a tube-like instrument inserted into the heart through a vein or artery (usually in the arm or leg) to detect problems with the heart and its blood supply
This condition can be life-threatening. But, it can be treated. Working closely with a doctor is crucial.
