Tachysystole
Tachysystole
Tachysystole (pronounced: ta-ki-sis-toh-lee) is a medical term that refers to an abnormally high rate of muscle contractions. This can occur in any of the body's muscles, but is most commonly associated with the heart.
Etymology
The term "tachysystole" comes from the Greek words "tachys" meaning "swift" and "systole" meaning "contraction".
Definition
Tachysystole is defined as more than five contractions in ten minutes, averaged over a 30-minute window. In the context of labor and delivery, tachysystole refers to more than five uterine contractions in 10 minutes.
Causes
Tachysystole can be caused by a number of factors, including stress, certain medications, and medical conditions such as premature labor and hyperthyroidism. It can also be a side effect of certain medical treatments, such as the use of oxytocin to induce labor.
Symptoms
Symptoms of tachysystole can include a rapid heartbeat, chest pain, shortness of breath, and, in severe cases, loss of consciousness. In pregnant women, it can also cause a decrease in fetal heart rate.
Treatment
Treatment for tachysystole depends on the underlying cause. This can include reducing stress, changing medications, or treating the underlying medical condition. In the case of labor, it may involve changing the position of the mother, providing hydration, or reducing the use of oxytocin.
