What is Sinus Tachycardia?
Sinus tachycardia occurs when your heart’s natural pacemaker, the sinoatrial node, sends quicker than standard signals, causing a rapid heart rate increase.
Causes of sinus tachycardia
Sinus tachycardia is a type of irregular heartbeat that is characterized by a faster than normal heart rhythm. Your heart’s sinus node generates electrical impulses that travel through the heart muscle, causing it to beat. A normal sinus rhythm has a heart rate of between 60 and 100 beats/minute.

The presence of tachycardia at rest could be the earliest sign of serious pathology. Thus, it is crucial for the clinician to rapidly identify the underlying cause of tachycardia and determine if it indicates urgent evaluation and/or treatment.
What is sinus tachycardia?
Sinus tachycardia refers to a faster-than-usual 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.
What is sinus rhythm?
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 60 to 100 beats per minute. Sometimes, these electrical impulses are sent out faster than normal, causing sinus tachycardia, which often results in a heart rate of over 100 beats per minute.

Is palpitation a symptom of IST?
Palpitations are a prominent symptom even though there may not be any "abnormal" heartbeats occurring. (That is, each heartbeat seems to arise from the sinus node, just as with the normal heart rhythm.) The symptoms experienced by sufferers of IST can be quite disabling and anxiety-producing.
Does Ivabradine help with IST?
Studies show the drug ivabradine can successfully treat some people with IST. 9 Ivabradine directly affects the "firing rate" of the sinus node, and thus reduces the heart rate. Ivabradine is approved in the U.S. as a treatment for heart failure in certain patients, but not IST.
What is sinus tachycardia?

What is it called when the heart beats faster than normal?
Tachycardia is when the heart beats faster than normal. There are different types of tachycardia, depending on the cause. Sinus tachycardia is when the sinus node, which is the natural pacemaker of the heart, fires electrical impulses abnormally quickly. People can have either normal or inappropriate sinus tachycardia.

What is the most common test for tachycardia?
An electrocardiogram, also called an ECG or EKG, is the most common tool used to diagnose tachycardia. It's a painless test that detects and records your heart's electrical activity using small sensors (electrodes) attached to your chest and arms.
