Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. People can have either normal or inappropriate sinus Inappropriate sinus tachycardia has no known cause. People who experience it may have an increased heart rate all of the time, even at rest.

These impulses cause the heart to contract. A properly functioning sinus node regulates the rhythm and speed of a person’s heart. According to the American Heart Association, a typical heart rate should fall within People can develop sinus tachycardia for different reasons. The underlying cause will determine the likely outcome of a person with this condition. Types of sinus tachycardia include normal and inappropriate sinus tachycardia. Normal sinus tachycardia Normal sinus tachycardia involves a known cause for the increase in heartbeat rate.

Sinus tachycardia is a common condition that happens sometimes in response to stressful situations. Your heart beats more than 100 times per minute, but usually returns to normal after the stressful event has passed. If your symptoms continue when your body is at rest, it’s a good idea to see your healthcare provider. Overview What is sinus tachycardia? When you have tachycardia, your heart rate is faster than 100 beats per minute. With sinus tachycardia, electrical signals from your heart’s sinoatrial (SA) node are telling your heart to beat faster than normal. This is a common condition that is usually a result of stressors like fear, exercise or not drinking enough fluids. What is inappropriate sinus tachycardia? If the cause of your sinus tachycardia is unknown, it’s called inappropriate sinus tachycardia. You still have more than 100 heartbeats per minute, but there is nothing unusual on your ECG ( Your ECG (electrocardiogram) can help your healthcare provider tell the difference between sinus tachycardia and other types of tachycardia. Some of these are: • • Sinus tachycardia with PVCs (premature ventricular contractions) and sinus tachycardia with PACs (premature atrial contractions) can give you a feeling of a racing or pounding heart (palpitations). However, these extra heartbeats are normally not a cause for concern. • Who does sinus tachycardia affect? Anyone can get sinus tachycardia. It’s a normal response to something that’s causing you stress. Symptoms and C...

Sinus tachycardia refers to a faster-than-typical heart rhythm. Your heart has a natural pacemaker called the sinus node, which generates electrical impulses that move through your heart muscle and cause it to contract, or beat. When these electrical impulses are transmitted normally, it’s referred to as normal sinus rhythm. Normal sinus rhythm typically results in a heart rate of Sometimes, these electrical impulses are sent out faster than this typical rhythm, causing sinus tachycardia. This results in a heart rate of If you have sinus tachycardia with no known cause, it’s called inappropriate sinus tachycardia (IST). This can cause an inexplicably fast heart rate even while you’re resting. In addition to rapid heart rate, IST can cause: • shortness of breath • chest pain • dizziness or fainting • • trouble exercising • anxiety In some situations, sinus tachycardia can be completely natural. For example, a fast heart rate is expected during strenuous exercise or after being startled. Other causes of sinus tachycardia may include: • • • some medications, such as those used in allergy or mental health treatment • pain • stimulants, such as • recreational drugs, such as cocaine Other potential but less common causes of sinus tachycardia may include the following underlying health conditions: • • an infection • damage to your heart muscle, such as from a previous • • • • • Doctors aren’t sure about the exact cause of IST, but it likely involves a combination of factors.

Sinus tachycardia: causes, ECG, normal variants & pathological variants Sinus tachycardia is the most common tachyarrhythmia (tachycardia).Sinus tachycardia is the result of an increased rate of depolarization (i.e increased Although sinus tachycardia is the most common tachyarrhythmia,itmay not always be straight forward to diagnose on the • Normal (physiologic) sinus tachycardia:The • Sinus tachycardia secondary to disease and medications: A wide range of diseases and medications may cause sinus tachycardia; e.g congestive • Inappropriate sinus tachycardia: When all the abovementioned causeshave been ruled outand the sinus tachycardia persists without any known cause, it may be classified as inappropriate sinus tachycardia. This diagnosis can only be established after all other causes have been ruled out. Inappropriate sinus tachycardia is presumably more common than previously thought and the condition may hamper the quality of life substantially. Thus, management of sinus tachycardia is aimed at finding secondary causes that may and must be treated or, when no cause can be found, establish a diagnosis of inappropriate sinus tachycardia. Although there are no evidence-based treatments for inappropriate sinus tachycardia, patients frequently benefit from obtaining a diagnosis,because itjustifies their suffering and symptoms (treatment alternatives are discussed below).

ECG strip showing a normal heartbeat ECG strip showing tachycardia Tachycardia in adults refers to a heart rate of more than 100 beats per minute. How that’s defined may depend on your age and physical condition. Types of tachycardias Atrial or Supraventricular Tachycardia (SVT) Atrial or supraventricular tachycardia (SVT) is a fast heart rate that starts in the upper chambers of the heart. Some forms of this tachycardia are paroxysmal atrial tachycardia (PAT) and paroxysmal supraventricular tachycardia (PSVT). With atrial or supraventricular tachycardia, electrical signals in the heart’s upper chambers occur abnormally. There may also be structural abnormalities of the heart.This interferes with electrical impulses coming from the sinus node, the heart’s natural pacemaker. The disruption results in a faster than normal heart rate. This rapid heartbeat keeps the heart’s chambers from filling completely between contractions, which may compromise blood flow to the rest of the body. Risk factors for Atrial or SVT In general, those most likely to have atrial or supraventricular tachycardia are: • Children (SVT is the most common type of arrhythmia in kids) • Women, to a greater degree than men • Young people with anxiety • People who are middle-aged and older You are at increased risk for atrial tachycardia or SVT if you: • Drink alcohol heavily • Smoke heavily or use illegal drugs, such as amphetamines and cocaine • Have coronary artery disease, have had heart surgery or othe...
