what happens if your heart rate gets too fast?

When your heart is beating too fast, it may not pump enough blood to the rest of your body. This can starve your organs and tissues of oxygen and can cause the following tachycardia-related signs and symptoms: Shortness of breath. Lightheadedness.

You can have a bout of SVT even when you're not stressed out or exercising hard. When your heart beats too fast, it can't pump out enough blood. You might feel tired, short of breath, or dizzy as a result of this condition that starts in the upper chambers of your heart.

Sometimes, it's normal for you to have a fast heartbeat. For instance, it's normal for your heart rate to rise during exercise or as a response to stress, trauma or illness. But in tachycardia (tak-ih-KAHR-dee-uh), the heart beats faster than normal due to conditions unrelated to normal physiological stress.

When you have SVT, the electrical system in your heart isn't working right. You might experience a sudden rapid heartbeat, which can lead to shortness of breath, chest pain and, in rare cases, loss of consciousness. SVT often ends suddenly. It stops either on its own or when you take an action to slow your heart rate.

Normally, your heart beats between 60 and 100 times a minute. Eating specific foods or drinking certain beverages can raise your heart rate to above 100, creating a feeling that your heart is fluttering, racing or skipping a beat. If it happens occasionally, it's likely nothing to worry about.

Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly. Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless.

When heart rate or rhythm changes are minor Your heart rate or rhythm can change when you are under stress or having pain. Your heart may beat faster when you have an illness or a fever. Hard physical exercise usually increases your heart rate, which can sometimes cause changes in your heart rhythm.

When the heart beats too rapidly, it pumps less efficiently and blood flow to the rest of the body, including the heart itself, is reduced. Because the heart is beating quicker, the muscles of the heart, or myocardium, need more oxygen.

If you're sitting down and feeling calm, your heart shouldn't beat more than about 100 times per minute. A heartbeat that's faster than this, also called tachycardia, is a reason to come to the emergency department and get checked out.

A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily.

If your heart is beating more than 90 times per minute, it may be struggling. You could be having a panic attack, but shortness of breath plus a rapid heart rate may be a sign of almost any significant heart or lung disease.

Tachycardia. Tachycardia means that your heart is beating much faster than normal, usually more than 100 beats per minute. Some forms of tachycardia are not serious and easily treated while others can be life-threatening.
137838
There are many heart rhythm disorders (arrhythmias) that can cause tachycardia. Sometimes, it's normal for you to have a fast heartbeat. For instance, it's normal for your heart rate to rise during exercise or as a response to stress, trauma or illness.

In some cases of AFib, the fibrillation of the atria causes the ventricles, or lower chambers of the heart, to beat too fast. This is called a rapid ventricular rate or response (RVR). If you have AFib with RVR you'll experience symptoms, typically a rapid or fluttering heartbeat.

Your heart might beat faster, slower or differently than usual for a few reasons. Rapid, fast heartbeat at rest could be caused by stress, caffeine, alcohol, tobacco, thyroid pills, cold medication, asthma drugs or diet pills.

Eating too fast may lead to weight gain, heart disease. Eating too quickly may add an extra size to your waistline, as well as raise your risk of heart disease, diabetes, and stroke, according to new research.

For some people, a slow heart rate does not cause any problems. It can be a sign of being very fit. Healthy young adults and athletes often have heart rates of less than 60 beats a minute. In other people, bradycardia is a sign of a problem with the heart's electrical system.
