Supraventricular Tachycardia Caused By Paracetamol
Good question: With no simple answer. There are many triggers like caffeine, nicotine, alcohol, excess thyroid hormone, anxiety, stress, decongestants eg pseudoephedrine, direct stimulants eg cocaine, etc. But you also have to have potential electrical connections in your heart that you're born with or acquire eg from rheumatic fever. ...Read more

Dr. says I have supraventricular tachycardia, after ekg, and has ordered a 14-day event monitor and echo. Pulse irregular. Could anxiety cause this?
Ineffective hrt beat: If your heart is beating extremely fast (as in supra-ventricular tachycardia) it has very little time to fill with blood between beats so very little blood will be pumped with every beat. As a result important organs like your brain, kidneys, liver and your heart itself will not receive the necessary amount of blood to continue functioning properly. ...Read more
Yes: Supraventricular tachycardia (svt) is a broad group of dysrhythmias that include atrial fibrillation (af). Svts are a very common rhythm abnormality and af among the commonest svts increasing in frequency as we age. Risk factors include thyroid disease, age, hypertension, diabetes, and several others. Treatments for SVT and af include medicines, pacemakers (if needed) and ablative procedures. ...Read more
See below: Supraventricular tachycardia (svt) is an episodic fast heart rate that usually originates in the upper chambers of the heart. It usually starts all of a sudden and stops all of a sudden, usually is not life threatening by itself, and is mostly rather easily treatable with a cardiac procedure called ablation which is performed by an electrophysiologist. ...Read more
Get evaluated: You need to find out why you are having the tachycardia and whether it is truly supra-ventricular tachycardia (svt) before you continue engaging in high level athletics. Many forms of svt can be treated and even "cured" so it is not worth the risk to continue sports until you know that it is safe to do so. See a cardiologist asap. ...Read more
Depends on the type: There are many types of supraventricular tachycardia. Among the different types; effects & frequency vary among persons. For example, for a very limited av nodal reentrant tachycardia once or twice a year that does not last long and does not go fast, the effects are usually benign. However, if the heart goes very fast you could pass out. Atrial fibrillation of any rate increases stroke risk. ...Read more
Origin, prognosis: Supra-ventricular tachycardia originates in the upper chambers of the heart (atria) and ventricular tachycardia in the lower chambers (ventricles). In very general terms, ventricular tachycardia may carry a more worrisome prognosis than its supra-ventricular counterpart but in many cases both types can be treated and in some cases (particularly supra-ventricular) can be "cured". See you doctor. ...Read more
No: Sinus tachycardia is the normal fast heart rate that results from a stressful situation, physically or emotionally (running, being upset, having fever, etc...). Svt is an arrhythmia that usually requires abnormalities of the electrical conduction system of the heart, and if frequent and troubling needs directed treatment. Sinus tachycardia does not require treatment of its own usually. ...Read more
Depends: Depends on how fast or how slow, the cause for the abnormal rate and whether it is causing any symptoms. Both abnormally slow and fast heart beats can cause congestive heart failure and syncope (fainting). Persistent fast heart beats can cause weakness of heart muscle referred to as tachycardia induced cardiomyopathy. ...Read more
Will i still be able to travel since I've been diagnosed with paroxysmal supraventricular tachycardia?
Can anyone please explain to me what supraventricular tachycardia (svt) is. My 16 year old is being tested?
See Below: Svt: tachycardia means the heart beats faster than normal originating supraventricular, above the ventricles, in the atria caused by abnormal electrical impulses. Because the heart is not contracting effectively, it may cause lightheadedness, dizzyness or fainting. This arrythmia is usually not dangerous but in a few people it can become dangerous. Your daughter must be assessed by a cardiologist. ...Read more
It depends: Whether supraventricular tachycardia (svt) causes problems in a fetus depends on how often and for how long the fetus remains in svt, and on the rate of the svt (how fast). Typically, if a fetus is having problems with svt, a fetal cardiac ultrasound will detect that the heart function is declining and there may be evidence for abnormal fluid collections (so called non-immune hydrops). ...Read more
