What does AVNRT mean in MEDICAL
Atrioventricular nodal reentrant tachycardia (AVNRT) is a type of abnormally fast heart rhythm. It is caused by an electrical circuit in and around the atrioventricular node that causes the heartbeat to become very rapid and produce a distinct pattern on an electrocardiogram (ECG). AVNRT typically affects young to middle-aged adults who do not have any underlying heart conditions. AVNRT is the most common cause of supraventricular tachycardia (SVT), and it can lead to palpitations, lightheadedness, chest pain, shortness of breath, and even fainting. Treatment for AVNRT typically includes medication or electrical cardioversion, both of which can restore normal heart rhythm.

Definition
Atrioventricular nodal reentrant tachycardia (AVNRT) is an abnormally fast heart rhythm caused by an abnormal electrical circuit in and around the atrioventricular node. The condition results in a rapid heartbeat that produces a distinctive pattern on an ECG. It is the most common form of supraventricular tachycardia (SVT).
Signs & Symptoms
Common signs and symptoms of AVNRT include palpitations, shortness of breath, chest pain, dizziness, lightheadedness, fatigue, and fainting. These symptoms are generally brief but can be distressing for those affected. In some cases they may be severe enough that emergency medical attention is required.
Causes & Risk Factors
The exact cause of AVNRT is unknown; however, it has been linked to certain underlying health conditions including congenital abnormalities or other cardiac problems such as narrowing of the coronary arteries or high blood pressure. Other risk factors include smoking, excessive alcohol use, diabetes mellitus, thyroid disease, obesity, family history of SVT or cardiac disease.
Diagnosis & Tests
AVNRT can usually be diagnosed with a physical exam and medical history along with electrocardiography (ECG). An ECG provides information regarding the electrical activity in the heart and can detect signs of AVNRT such as a characteristic waveform called delta waves. Other diagnostic tests may also be used including echocardiography or cardiac stress testing if necessary to rule out other causes for an abnormally fast heart rate such as valvular disease or cardiomyopathy.
Treatment & Medication
Treatment for AVNRT usually involves medications such as beta-blockers or calcium channel blockers which help slow down the heart rate or block conduction through pathways associated with SVT episodes. Electrical cardioversion may also be used if medications are ineffective. Cardioversion uses electricity to restore normal sinus rhythm while minimizing discomfort associated with SVT attacks.
Essential Questions and Answers on atrioventricular nodal reentrant tachycardia in "MEDICAL»MEDICAL"
What is Atrioventricular Nodal Reentrant Tachycardia (AVNRT)?
Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a type of supraventricular tachycardia caused by an abnormal electrical circuit in the heart. This circuit uses part of the atrioventricular node (which connects the atria and ventricles to each other), as well as another nearby electrical pathway, and causes an abnormally fast heartbeat.
What are the symptoms of AVNRT?
The main symptom of AVNRT is an abnormally rapid heart rate, which can cause palpitations, shortness of breath, dizziness or light-headedness. It may also cause chest pain or discomfort.
Who is at risk for developing AVNRT?
People who have had previous heart surgery or certain types of heart disease are at higher risk for developing AVNRT. Other medical conditions such as thyroid disease or sleep apnea may also increase one’s risk.
What are some treatments for AVNRT?
Treatments for AVNRT vary depending on severity and symptoms, but may include medications such as beta blockers, calcium channel blockers or antiarrhythmic drugs; electrical cardioversion; or catheter ablation - which involves using energy to destroy specific parts of the abnormal electrical circuit in order to stop the abnormal heartbeat.
How successful is catheter ablation for treating AVNRT?
Catheter ablation has been shown to be very successful in treating AVNRT - with success rates up to 95%. It is often the preferred treatment option due to its high success rate and low risk compared to other options.
Is there any long-term damage from having AVNRT?
Patients who experience recurrent episodes of AVNRT without appropriate treatment may develop more serious arrhythmias such as ventricular fibrillation – which can lead to cardiac arrest and death if not treated promptly. Therefore it is important that individuals with suspected AVNRT seek medical attention right away.
What lifestyle changes can I make to reduce my risk of having episodes of AVNRT?
Lifestyle modifications such as reducing stress, getting adequate sleep, avoiding recreational drugs, quitting smoking and limiting alcohol consumption can all help reduce your risk of experiencing episodes of tachycardia related to AVNRF. Additionally, regular exercise and maintaining a healthy weight can also help reduce your risk.
Is it dangerous if I ignore the symptoms of an episode of VRANRt?
Yes - ignoring potentially dangerous symptoms associated with VRANRt can be life threatening since prolonged episodes can lead to more serious arrhyhtmias such as ventricular fibrillation that could result in cardiac arrest or sudden death without immediate intervention. Therefore it is important that you seek medical attention immediately if you experience any concerning symptoms associated with this condition.
What should I do while waiting for medical attention during an episode of VRANRt?
During an episode it is recommended that you remain calm and focus on relaxation techniques such as deep breathing exercises or progressive muscle relaxation. If possible you should lie down with your legs elevated above your head so that gravity will assist in keeping blood flowing properly throughout your body until arrive at medical care.
Final Words:
Atrioventricular nodal reentrant tachycardia (AVNRT) is a type of arrhythmia caused by abnormal electrical activity in and around the atrioventricular node leading to rapid heartbeat producing a distinctive pattern on an electrocardiogram (ECG). Common signs and symptoms range from palpitations and lightheadedness to chest pain and fainting depending on its severity. Its causes are still largely unknown although underlying health conditions such as coronary artery narrowing can increase its risk factor along with lifestyle factors like smoking or diabetes mellitus. Diagnosis typically involves ECG tests alongside echocardiographs if necessary while treatment typically involves medications like beta-blockers or calcium channel blockers along with electric cardioversion if necessary.
