Causes of atrial tachycardia include high blood pressure, drinking too much, heart tissue damage, a congenital abnormality of the heart, and drinking many beverages with too much caffeine, according to Mayo Clinic.
Types of atrial tachycardia include atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular tachycardia and ventricular fibrillation, reports Mayo Clinic. People with ventricular fibrillation may suffer heart disease and have had trauma in the past.
Symptoms of atrial tachycardia include a pounding pulse, palpitations, lightheadedness and chest discomfort, explains WebMD. Other symptoms are breathing difficulties, sweating, fatigue and throat tightness.
Women are at a higher risk for atrial tachycardia than men, states Healthline. Emotional health can also affect the risk of getting tachycardia. To diagnose, doctors typically recommend electrocardiogram that calculates the electrical activity of the heart. The doctor may also check the blood pressure to diagnose the condition.
Most people with atrial tachycardia do not require treatment for the condition, according to Healthline. However, a doctor may advise treatment if the episodes keep on occurring or last for a long time. During treatment, the doctor may recommend vagal maneuvers to reduce the heart rate. If vagal maneuvers do not work, medications such as propafenone or flecainide may help. The doctor may advise a reduction in caffeine intake.
