What is the most common cause of sinus tachycardia?
People develop sinus tachycardia when the sinus node in the heart sends electrical impulses more quickly than normal. It can occur as a result of a particular trigger, such as exercise, caffeine, or stress.
Is tachycardia a serious problem?
Tachycardia may not cause any symptoms or complications. But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death.
When should I worry about sinus tachycardia?
In some patients, sinus tachycardia may indicate other concerns, such as increased thyroid activity, anemia, damage to the heart muscle due to a heart attack, or severe bleeding. An isolated occurrence of sinus tachycardia in response to an identifiable trigger may not require medical attention.
What are the main causes of tachycardia?
Common causes of Tachycardia include: Heart-related conditions such as high blood pressure (hypertension) Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumors, or infections.
Is it normal to have sinus tachycardia?
Normal sinus tachycardia In some situations, sinus tachycardia is completely normal. For example, sinus tachycardia is expected during strenuous exercise or after being startled. Other things that can cause sinus tachycardia include: anxiety or emotional distress.
Can sinus tachycardia be cured?

What happens if tachycardia is untreated?
Over time, untreated and frequent episodes of supraventricular tachycardia (SVT) may weaken the heart and lead to heart failure, particularly if there are other medical conditions. In extreme cases, an episode of SVT may cause unconsciousness or cardiac arrest.
Does tachycardia shorten lifespan?
Is Supraventricular Tachycardia dangerous? In the vast majority of cases SVT is a benign condition. This means that it will not cause sudden death, damage the heart or cause a heart attack. It will not shorten life expectancy.
When is tachycardia an emergency?
If you’re sitting down and feeling calm, your heart shouldn’t beat more than about 100 times per minute. A heartbeat that’s faster than this, also called tachycardia, is a reason to come to the emergency department and get checked out. We often see patients whose hearts are beating 160 beats per minute or more.
Is sinus tachycardia life threatening?
While inappropriate sinus tachycardia is not life-threatening for most people, you should schedule an appointment with your doctor to discuss your risk. Complications of sinus tachycardia include: Blood clots. A blood clot could form and lead to a heart attack or stroke. Heart failure. If the heart cannot pump enough blood, heart failure can occur.
What is tachycardia and how dangerous is it?
When your heart beats more than 100 times a minute, that’s tachycardia. Because your heart beats too often, it doesn’t have the time it needs to fill with blood between beats. This can be dangerous if your heart can’t supply all your cells with the blood and oxygen they need.
What is the best treatment for sinus tachycardia?
Valsalva Maneuver. The Valsalva maneuver is one of the principal vagal maneuvers.
Is tachycardia life threatening?
Usually this type of tachycardia is not life-threatening but it may be a sign of a more serious heart condition. Supraventricular tachycardia (SVT) happens somewhere above your heart’s lower chambers (ventricles). Generally, this condition is not dangerous unless you have other heart health problems. Ventricular tachycardia can be life-threatening.
