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.
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.
Sinus tachycardia is an increase in the heart rate. In this condition, the heart’s natural pacemaker, the sinus node, sends out electrical signals faster than usual. The heart rate is faster than normal, but the heart beats properly.
If a fast heart rate is caused by exercise or stress, it's called sinus tachycardia. Sinus tachycardia is a symptom, not a condition. Most heart conditions can lead to different forms of tachycardia.
Sinus tachycardia is a regular cardiac rhythm in which the heart beats faster than normal. While it is common to have tachycardia as a physiological response to exercise or stress, it causes concern when it occurs at rest.
Sinus tachycardia is when the sinus node in the heart sends electrical impulses faster than the normal rate. Learn more about causes and treatments here.
Sinus tachycardia is a rhythm in which the rate of impulses arising from the sinoatrial (SA) node is elevated. Sinus tachycardia is most often a normal and physiologic response, for example during exercise. However, sinus tachycardia can in some instances be inappropriate or pathologic.
Sinus tachycardia is when your body sends out electrical signals to make your heart beat faster. Hard exercise, anxiety, certain drugs, or a fever can spark it.
Sinus tachycardia (ST) is ubiquitous, but its presence outside of normal physiological triggers in otherwise healthy individuals remains a commonly encountered phenomenon in medical practice.
When you’ve had a scare or are very emotional or anxious, or are exercising, your heart may send signals more frequently for a short time. This is called sinus tachycardia and goes away when you calm down or rest. Other types of tachycardia can come back regularly and can be more serious.
