The symptoms of atrial tachycardia include a rapid pulse, dizziness, lightheadedness and fatigue, according to Drugs.com. Other symptoms include shortness of breath, jumping or fluttering in the chest, chest pain and the need to urinate more often than usual.
Atrial tachycardia is a condition that causes the heart to beat abnormally fast due to excessive electrical signals. While a normal resting heart rate is 60 to 80 beats per minute, a heart affected by atrial tachycardia may beat anywhere from 100 to 300 times per minute, states Drugs.com.
While risk for atrial tachycardia increases with age, electrolyte imbalance and medical conditions such as hyperthryoidism may lead to atrial tachycardia. The condition can be controlled with medication or a pacemaker, states Drugs.com.
