Inappropriate Sinus Tachycardia synonyms

Inappropriate Sinus Tachycardia (IST) is a medical condition characterized by an abnormally fast heart rate originating from the sinus node, the natural pacemaker of the heart. It is often referred to by several other terms that describe the same condition:

• Non-physiological Sinus Tachycardia: This term emphasizes that the increased heart rate is not a normal response to physical activity or stress.


• Chronic Sinus Tachycardia: This term highlights the persistent nature of the condition, as the elevated heart rate is present over an extended period of time.


• Idiopathic Sinus Tachycardia: This term is used when the underlying cause of the condition is unknown.


• Functional Sinus Tachycardia: This term suggests that the increased heart rate is a result of a dysfunction in the sinus node or its regulation.


• Hyperdynamic Sinus Tachycardia: This term indicates that the heart is excessively active, leading to a rapid heart rate.

Regardless of the terminology used, individuals with Inappropriate Sinus Tachycardia experience a heart rate that exceeds the normal range, typically exceeding 100 beats per minute at rest. This condition can cause various symptoms such as palpitations, shortness of breath, fatigue, and lightheadedness.

It is important for individuals with Inappropriate Sinus Tachycardia to consult with a healthcare professional for an accurate diagnosis and appropriate management. Treatment options may include medications to regulate heart rate, lifestyle modifications, and in some cases, catheter ablation to target the abnormal electrical pathways in the heart.
