How do you treat SVT?
Calcium channel or beta blockers can help correct heart rhythm. If you have SVT only 1 or 2 times a year, you may take beta-blockers or calcium channel medicines by mouth (orally) as needed. If your SVT is more frequent, you may need to take medicine every day. Some people may need to take several medicines to prevent episodes of SVT.

What is the best treatment for SVT?
In most patients, the drug of choice for acute therapy is either adenosine or verapamil. The use of intravenous adenosine or the calcium channel blocker verapamil are considered safe and effective therapies for controlling SVTs. Click to see full answer.
Can adenosine be used for tachycardia?
Now, adenosine can also be used for regular monomorphic wide-complex tachycardia. When given as a rapid IV bolus, adenosine slows cardiac conduction particularly affecting conduction through the AV node.
How to treat SVT?
The Valsalva maneuver Tightly close your mouth, pinch your nose shut, and try to breathe out as hard as you can for 10 to 15 seconds. The Valsalva maneuver is always the first-line treatment for an attack of SVT. Cold water Apply ice water to the face for about five seconds.
What are the symptoms of supraventricular tachycardia?
The most common symptoms of supraventricular tachycardia include: Rapid heart rate. Palpitations. Chest discomfort.
Why does my heart beat so fast?
A glitch in nerve signals rather than a problem with heart muscles causes the heart to beat too fast (tachycardia). The heart is divided into four chambers. The two upper chambers, the atria, fill with the blood returning from the body (right atrium) or the lungs (left atrium).
What is the heartbeat?
A heartbeat begins when the atria contract and push blood into the bottom two chambers—the ventricles. After the ventricles fill with blood, they contract and push blood out to the lungs (right ventricle) or the rest of the body (left ventricle).
How does the AV node work?
This node pauses the signal for a tiny fraction of a second as the upper chambers push blood into the lower chambers. The AV node then passes the nerve signal to the ventricles, causing them to contract. This well-timed one-two beat is the basic rhythm of the heart and can easily be heard through a stethoscope.
Does adenosine help with SVT?
When taken as an injection, adenosine slows down the AV node, the primary cause of SVT symptoms. If intravenous adenosine does not work, the next step will be intravenous calcium-channel blockers ( diltiazem or verapamil ), beta-blockers ( esmolol or metoprolol ), or antiarrhythmic medications (procainamide or amiodarone ). All of these drugs slow down the AV node.
What is the heart's pacemaker?
Sometimes referred to as the heart’s “pacemaker,” this nerve bundle first sends out electrical impulses that cause the two upper chambers to contract. The nerve signal terminates at another node, the atrioventricular node (AV node), a kind of crossing gate to the lower chambers.
What to do if you have a SVT?
If the SVT episode continues, you should go to the emergency room. There, you might be given a medicine called adenosine, which also slows the electrical impulses in the heart, or another medicine called verapamil. In rare cases, you might require an electrical shock to get your heart back into a normal rhythm.
What are the symptoms of SVT?
Common symptoms are palpations, dizziness, chest pain, and feeling like you are about to faint. Treatment for SVT includes drug therapies and catheter ablation. What type of therapy is best for you depends on the type of SVT you have, how often it occurs, and the degree and length of symptoms.
Can you get SVT without symptoms?
In most cases, if you experience short episodes of supraventricular tachycardia (SVT) with no symptoms, your health care professional may recommend no therapy. However, if you do have symptoms, frequent episodes, or both, then you will likely require treatment.
How to cure SVT?
This can help cure SVT. Your healthcare provider puts a thin, flexible tube (catheter) into a blood vessel in the groin. He or she then gently pushes it up into your heart. The area of your heart that causes your SVT is then either cauterized with heat or scarred with freezing energy.
What are the symptoms of a syringe?

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

How to get your heart to go back to normal?
This method uses easy exercises to spark the vagus nerve, which helps set the beating of your heart. Begin by bearing down as if you were sitting on a toilet.
How does a catheter work?
You will be awake during this procedure. Your doctor inserts a catheter, or narrow plastic tube, into an artery or vein in your leg or groin, after numbing the area. The doctor then guides the catheter up to your heart. It records the electrical impulses, trying to find where the problem is coming from.
How does a zap work?
It records the electrical impulses, trying to find where the problem is coming from. Once they are zeroed in on the location, they’ll use an electrode to zap the area, either with heat or cold. This procedure is usually successful and has few side effects.
What is the best medication for narrow complex SVT?
When vagal maneuvers fail to terminate stable narrow-complex SVT, the primary medication of choice is adenosine. For the unstable patient with a regular and narrow QRS complex, adenosine may also be considered prior to synchronized cardioversion.
How is adenosine absorbed?
When injected into the body, adenosine is rapidly absorbed by red blood cells and blood vessel endothelial cells and metabolized for natural uses throughout the body. In light of this adenosine should be administered by RAPID intravenous bolus so that a significant bolus of adenosine reaches the heart before it is metabolized.
Does adenosine cause chest pain?
Some side effects of adenosine administration include flushing, chest pain/tightness, brief asystole or bradycardia. Make sure that adenosine is not used for irregular, polymorphic wide-complex tachycardia and unstable VT. Use in these cases may cause clinical deterioration. Return to ACLS Drugs Main Page.
Can adenosine be used for tachycardia?
Now, adenosine can also be used for regular monomorphic wide-complex tachycardia. When given as a rapid IV bolus, adenosine slows cardiac conduction particularly affecting conduction through the AV node.
