How do I check my heart rate (pulse)?

Your healthcare provider will show you how to check your pulse, and how often to check it. Write down how fast your pulse is and if it feels regular or like it is skipping beats. Also write down the activity you were doing if your heart rate is above 100. Bring the information with you to your follow-up appointment.

How can I prevent or manage atrial tachycardia?

• Talk to your healthcare provider about all your current medicines. He or she may change a medicine if it is causing your fast heart rate. Do not stop taking any medicine unless directed by your provider.
• Have less caffeine. Caffeine can increase your heart rate.
• Limit or do not drink alcohol. Alcohol can increase your heart rate. Ask your healthcare provider if it is okay for you to drink any alcohol. He or she can help you set limits for the number of drinks you have in 24 hours and in a week. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
• Do not smoke. Nicotine and other chemicals in cigarettes can cause damage to your heart. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
• Do not use illegal drugs. Drugs such as meth and cocaine can increase your heart rate. Talk to your healthcare provider if you use illegal drugs and need help to quit.
• Get more rest. Fatigue can cause your heart rate to increase.
• Eat heart-healthy foods. These include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Replace butter and margarine with heart-healthy oils such as olive oil and canola oil.
• Exercise regularly and maintain a healthy weight. Ask about the best exercise plan for you. Ask your healthcare provider what a healthy weight is for you. Ask him or her to help you create a safe weight loss plan if you are overweight.
• Learn ways to cope with stress. Stress, fear, and anxiety can cause a fast heart rate. Your healthcare provider may recommend relaxation techniques and deep breathing exercises. Your healthcare provider may recommend you talk to someone about your stress or anxiety, such as a counselor or a trusted friend.
