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:
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.
