Question: what is tachycardia sinus?

Sinus tachycardia refers to a faster-than-usual heart rhythm. It can occur with exercise, anxiety, or stress, but it can sometimes signal an underlying health condition.

Question: causes of tachycardia sinus?

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:
anxiety or emotional distress
fever
some medications, such as those used in allergy or mental health treatment
pain
stimulants, such as caffeine or nicotine
recreational drugs, such as cocaine
Other potential but less common causes of sinus tachycardia may include the following underlying health conditions:
anemia
an infection
damage to your heart muscle, such as from a previous heart attack
hyperthyroidism
low blood pressure
lung disease
pulmonary embolism
severe bleeding
Doctors aren't sure about the exact cause of IST, but it likely involves a combination of factors. These may include:
a problem with your sinus node
unusual nerve signaling that causes your heart rate to increase
dysfunction of the nerves that work to lower your heart rate

Question: What are the usual symptoms of tachycardia sinus?

In most cases
, sinus tachycardia is asymptomatic (you don't feel any symptoms). However, it's possible to experience the following symptoms related to this condition:
heart palpitations
chest pain
dizziness or lightheadedness
fainting
breathing difficulties

Question: How do doctors usually treat tachycardia sinus?

Occasional sinus tachycardia from exercise and other factors that cause short-term increases in your heart rate generally don't require treatment. However, a doctor may consider treatment if you have a consistently higher heart rate than typical, especially during times of rest.
First, a doctor will need to determine the underlying cause of sinus tachycardia before prescribing treatment. Depending on how fast your heart rate is, a doctor might prescribe beta-blockers or calcium channel blockers to lower your heart rate.
In severe cases that don't respond to medication or lifestyle changes, you may need a cardiac ablation procedure. This involves using energy to destroy a tiny part of the heart tissue in the area causing tachycardia.

Question: How do doctors usually figure out if someone has tachycardia sinus, diagnosis?

To diagnose sinus tachycardia, a doctor may order tests to measure how your heart is working. These may include:
an electrocardiogram (EKG), which measures electrical activity in your heart
a Holter monitor, which measures your heart rate over 24 hours
chest X-rays
pulse oximetry
blood testing for cardiac enzymes, glucose, and complete blood count (CBC)

Question: What are the ways to prevent tachycardia sinus?

Preventing sinus tachycardia may depend on treating any underlying causes.
For example, if you have hyperthyroidism and it's causing a higher-than-typical heart rate, then treating your overactive thyroid gland may help prevent sinus tachycardia.
In other cases, you may be able to prevent sinus tachycardia with certain lifestyle changes. You may consider talking with a doctor to see if the following strategies may help:
limiting caffeine intake
limiting or avoiding alcohol
quitting smoking, if you smoke
participating in an exercise program
eating a heart-healthy diet
achieving or maintaining a moderate weight
managing stress
