An AED is a portable defibrillation device that can deliver a shock to reset the heart rhythm.

If an automated external defibrillator (AED) is available nearby, have someone get the device for you, and then follow the instructions.

Push hard and fast on the center of the chest at a rate of 100 to 120 compressions a minute until paramedics arrive.

If you're not trained in CPR or worried about giving rescue breaths, then provide hands-only CPR.

CPR can help maintain blood flow to the organs until an electrical shock (defibrillation) can be given.

If you or someone nearby is well trained in CPR, start CPR.

Call 911 or the emergency number in your area.

Soon the affected person's breathing and pulse will stop. Seek immediate medical help if you have shortness of breath, weakness, dizziness, lightheadedness, fainting or near fainting, and chest pain or discomfort.Ī type of tachycardia called ventricular fibrillation can cause blood pressure to drop dramatically. If you feel like your heart is beating too fast, make an appointment to see a health care provider. When to see a doctorĪ number of things can cause a rapid heart rate (tachycardia). The condition may be discovered when a physical exam or heart tests are done for another reason. Some people with tachycardia have no symptoms.

Sensation of a racing, pounding heartbeat or flopping in the chest (palpitations).

In general, tachycardia may lead to the following signs and symptoms: As a result, the organs and tissues may not get enough oxygen. When the heart beats too fast, it may not pump enough blood to the rest of the body. In other instances, a procedure called catheter ablation may be used to scar tissue that's creating the erratic signals- in the hopes of getting back to that normal beat. In some cases, atrial fibrillation can be corrected with medication or by administering a shock to a sedated patient's heart. Kusumoto says atrial fibrillation decreases the heart's blood pumping efficiency and puts a patient at higher risk for blood clots, heart failure, and stroke. Other times, people just notice that they're more short of breath when they walk upstairs." Fred Kusumoto is an electrophysiologist at Mayo Clinic.įRED KUSUMOTO, M.D.: "In some cases people feel their heart palpitating or beating very, very fast or a flip-flop in their heart or chest area. Atrial fibrillation interrupts this regular beat.įRED KUSUMOTO, M.D.: "In atrial fibrillation, instead of the atria squeezing in a normal regular fashion, the atria beat irregularly and chaotically." Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning.

This serious problem can lead to death if the heart rhythm isn't restored within minutes. Rapid, chaotic electrical signals cause the ventricles to quiver instead of contracting in a coordinated way. Supraventricular tachycardia causes episodes of a pounding heartbeat (palpitations) that begin and end abruptly. Supraventricular tachycardia is a broad term that includes arrhythmias that start above the ventricles. But episodes lasting more than a few seconds can be life-threatening. Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. The rapid heart rate doesn't allow the ventricles to fill and squeeze (contract) to pump enough blood to the body. This type of arrhythmia starts in the lower heart chambers (ventricles). People who have atrial flutter also often have atrial fibrillation at other times. Episodes of atrial flutter may go away themselves or may require treatment. Atrial flutter is similar to A-fib, but heartbeats are more organized. A-fib may be temporary, but some episodes won't end unless treated.

Chaotic, irregular electrical signals in the upper chambers of the heart (atria) cause a fast heartbeat. This is the most common type of tachycardia. Common types of tachycardia caused by irregular heart rhythms (arrhythmias) include: Other types of tachycardia are grouped according to the part of the heart responsible for the fast heart rate and the cause. Sinus tachycardia refers to a typical increase in the heart rate often caused by exercise or stress. There are many different types of tachycardia. Treatment for tachycardia may include specific maneuvers, medication, cardioversion or surgery to control a rapid heartbeat. But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death.

Tachycardia may not cause any symptoms or complications.
