WHAT YOU NEED TO KNOW:
Tachycardia (fast heart rate) is when your heart rate is 100 beats per minute or more at rest. It is normal for the heart rate to increase with activity or exercise and then decrease when you stop. A fast heart rate at rest may be caused by strong emotions, fever, activity, some medicines, drugs, or caffeine.
Call your local emergency number (911 in the US) or have someone call if:
- You have any of the following signs of a heart attack:
- Squeezing, pressure, or pain in your chest
- You may also have any of the following:
- Discomfort or pain in your back, neck, jaw, stomach, or arm
- Shortness of breath
- Nausea or vomiting
- Lightheadedness or a sudden cold sweat
- You cannot be woken.
Call your doctor or cardiologist if:
- Your pulse is faster than you were told it should be.
- You have a fast heart rate often.
- You feel weak or dizzy.
- You have questions or concerns about your condition or care.
- Medicines can help control your heart rate or rhythm. You may need more than one medicine to treat your symptoms.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Check your heart rate (pulse) as directed:
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.
Help prevent a fast heart rate:
- 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 want to quit.
- Get more rest. Fatigue can cause your heart rate to increase. Ask your healthcare provider about the best exercise plan for you.
- 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.
- 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.
Follow up with your doctor or cardiologist as directed:
You may need more tests. Write down your questions so you remember to ask them at your visit.
