Jun 5, 2022 · 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.

Apr 7, 2025 · Sinus tachycardia refers to a faster-than-usual heart rhythm. It may occur with exercise, anxiety, or stress, but it can also signal an underlying health condition. Your heart has a natural ...

Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans).

May 23, 2023 · 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 the most common tachyarrhythmia (tachycardia). Sinus tachycardia is the result of an increased rate of depolarization (i.e increased automaticity) in the sinoatrial node. This simply means that the sinoatrial node discharges electrical impulses at a …

Look for regular rate and presence of p-waves to support diagnosis of sinus tachycardia; Management. Tailored to specific cause of sinus tachycardia: Fluids for dehydration; Blood for hemorrhage; Anticoagulation/thrombolytics for PE; Antibiotics and fluids for sepsis; Benzodiazepines for alcohol withdrawal; Supportive care for intoxication
