What is electrocardioversion?
Electrocardioversion. This is a shock to the heart to restart a normal rhythm right away. This may be done if you have a severe episode of SVT.
Overview
When your heart rhythm isn’t normal or the speed of the heartbeats isn’t right, you might have an arrhythmia. There are different names for different kinds of arrhythmias, depending on where they happen in the heart and what causes the problem. Tachycardia means your heart is beating too fast.
Symptoms and Causes
A problem with your heart’s electrical signals or circuitry causes SVT, but some people may not be aware of what brings on their symptoms. Others have a clear “trigger” like stress or exercise that starts their SVT. Things that can bring about symptoms include:
Diagnosis and Tests
Your healthcare provider will most likely do an electrocardiogram (EKG or ECG). If your provider needs to study your heart for a longer amount of time, they may ask you to wear a heart monitor that records the electrical activity in your heart.
Management and Treatment
You may not need treatment. Some people may feel better after resting more, drinking less coffee or alcohol or after quitting smoking.
Prevention
If your SVT (supraventricular tachycardia) is from causes you can control, you can:
Living With
Lifestyle changes can help with SVT (supraventricular tachycardia). You can:
What is a SVT?
Supraventricular tachycardia, or SVT, is a type of rapid heartbeat that begins in the upper chambers of the heart. Most cases don't need to be treated. They go away on their own.
What causes supraventricular tachycardia?
Sometimes, another health condition causes supraventricular tachycardia. You may have already been diagnosed with one of the following: 1 Coronary artery disease (blocked, inflamed, or narrow arteries) 2 Hyperthyroidism, which is an overactive thyroid 3 A lung disease 4 Wolff-Parkinson-White Syndrome, which is an electrical pathway problem present from birth
What is the best medicine to stop your heart from racing?
You might get a shot of a fast-acting medicine to block the electrical impulses that are causing your heart to race. Examples include adenosine (Adenocard or Adenoscan) and verapamil (Calan, Verelan).
What is SVT in heart?
SVT occurs when the electrical signals that coordinate your heartbeats don't work properly.
Where does SVT start?
SVT starts above the heart's ventricles (supraventricular) in the two upper chambers or a cluster of cells called the atrioventricular (AV) node.
What are the symptoms of supraventricular tachycardia?
They include sweating, poor feeding, pale skin and a rapid pulse. If your infant or young child has any of these symptoms, ask your child's doctor about SVT screening.
How many times does the heart beat during a SVT?
During an episode of SVT, your heart beats about 150 to 220 times per minute, but it can occasionally beat faster or slower. Most people with supraventricular tachycardia live healthy lives without restrictions or treatment.
Is supraventricular tachycardia life threatening?
When to see a doctor. Supraventricular tachycardia is generally not life-threatening unless you have heart damage or other heart problems. However, in extreme cases, an episode of SVT may cause unconsciousness or cardiac arrest.
Can thyroid problems cause supraventricular tachycardia?
Thyroid problems. Having an overactive or underactive thyroid gland can increase your risk of supraventricular tachycardia.
Do people with SVT have symptoms?
Some people with SVT have no signs or symptoms at all.
What causes SVT in children?
Causes of SVT. Supraventricular tachycardia is by far the most common heart arrhythmia seen in infants and children. There are many types of SVT, but the most common form in children occurs when there is an extra electrical connection between the top and bottom chambers of the heart, called an accessory electrical pathway.
How often should a child with SVT see a cardiologist?
Children with SVT should see a cardiologist once or twice every year for management of their medications and follow-up electrocardiograms. However, older children who have had successful ablation procedures for SVT may not need ongoing follow-up care. Reviewed by V. Ramesh Iyer, MD, MRCP.
How to get rid of supraventricular tachycardia in children?
Depending on your child's age and the severity and frequency of symptoms, the cardiologist may recommend a catheter ablation procedure to permanently eliminate SVT. During ablation, several large IVs (small plastic tubes) are placed in the main blood vessels in the legs. Then, catheters (thin tubes) are advanced up through the veins and into the heart. Electrical signals from the catheters help locate the extra electrical connection, which can then be destroyed and eliminated. The procedure takes several hours and most children can go home on the same day. After successful treatment with ablation, your child should not experience any SVT episodes.
What to do if tachycardia does not stop?
When tachycardia does not stop on its own or with vagal maneuvers, we may recommend a daily medication to prevent SVT from occurring. We may also treat SVT with an IV medicine, which immediately stops a fast heart rate.
What are the symptoms of supraventricular tachycardia?
Signs and symptoms of supraventricular tachycardia. Symptoms of supraventricular tachycardia in children may include: Heart palpitations — an uncomfortable sensation caused by the heart beating hard and fast. Rapid heartbeats that occur suddenly and randomly. Chest pain.
Can a baby die from SVT?
Symptoms of SVT in babies are subtle and often involve poor feeding, vomiting, or a general decrease in the baby’s activity level and alertness. Supraventricular tachycardia virtually never causes sudden death. Patients with SVT usually do not have any symptoms when they are not having these attacks.
Can a child with SVT live a normal life?
Please speak with your child’s cardiologist about your child’s particular condition and long-term outcome. In general, most children with SVT lead completely normal lives and have normal life expectancy.
What is a supraventricular tachycardia?
Supraventricular tachycardia (SVT) is an arrhythmia initiated above the ventricles, at or above the atrioventricular (AV) node. This cardiac rhythm occurs due to improper electrical conduction within the heart that disrupts the coordination of heartbeats. Early beats occur within the atria of the heart due to improperly functioning electrical connections, resulting in a rapid heart rate such that the heart does not have enough time to fill the atria with blood before contraction of the atria. This can lead to the patient feeling dizziness or lightheadedness because the brain is not receiving adequate oxygen or blood. The onset of this dysrhythmia is typically sudden, and may be prompted by emotional or physical stress.
What is the heart rate of a person with supraventricular tachycardia?
Paroxysmal supraventricular tachycardia is considered an intermittent supraventricular tachycardia that occurs at random, with a heart rate of 150-220 beats per minute. Paroxysmal supraventricular tachycardia is another name for supraventricular tachycardia.
What should be done before cardioversion?
Before performing cardioversion, the healthcare provider should ensure the patient has IV access and equipment is at the ready for suctioning, intubation, and measuring oxygen saturation . Contingent on the severity of the patient’s symptoms and how hemodynamically unstable they may be, sedation medication should be administered before initiating cardioversion. If all elements are in place, synchronized cardioversion should then be conducted. Recommendations specific to the cardioverter being utilized should be followed when determining appropriate settings for energy levels during shock delivery. If the patient’s cardiac rhythm remains unchanged following cardioversion, the healthcare provider or team should re-evaluate any potential underlying causes contributing to the patient’s condition. The energy level should then be increased for the next attempt at cardioversion.
What is the purpose of the Valsalva maneuver?
The Valsalva maneuver is an example of a vagal maneuver intended to stimulate the parasympathetic nervous system. This results in a slowing of the development of an impulse at the sinus node of the heart, which then reduces the speed of conduction at the AV node, extending the refractory period at the AV node, and decreasing the force of ventricular contractions. The Valsalva maneuver is completed by a patient modifying their breathing, where they exhale against the glottis, holding this for 10-15 seconds. The patient can do this by bearing down as if they were to have a bowel movement, blowing through a straw or syringe, or applying cold water or ice packs to their face.
How fast does a ventricular rate vary in SVT?
Understanding the underlying mechanism is useful in understanding the clues on ECG. Ventricular rates in SVT may vary from 150 to 250 beats/min. However, the rate may be slower in older patients and in patients taking AV nodal blocking medications (i.e., calcium-channel blockers, β-blockers and digoxin).7
What level of evidence is needed for SVT?
Patients with SVT should be educated on how to perform vagal manoeuvres for ongoing management of SVT (class I recommendation, level C-LD evidence)

What is a supraventricular tachycardia?
Supraventricular tachycardias are usually narrow-complex tachycardias with a QRS interval of 100 ms or less on an electrocardiogram (ECG). Occasionally, they may show a wide QRS complex in the case of a pre-existing conduction delay, an aberrancy due to rate-related conduction delay or a bundle branch block.
When is synchronized cardioversion recommended?
Synchronized cardioversion is recommended for acute treatment in patients with hemodynamically stable SVT when pharmacologic treatment is ineffective or contraindicated ( class I recommendation, level B-NR evidence)
What is the best treatment for a symtomatic sinus rhythm?
Oral β-blocker, diltiazem or verapamil treatment is useful for ongoing management in patients with symptomatic SVT who do not have ventricular pre-excitation during sinus rhythm (class I recommendation, level B-R evidence)
What is the class of vagal manoeuvres?
Vagal manoeuvres are recommended for acute treatment in patients with regular SVT (class I recommendation, level B-R evidence)
