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.
