Question

What happens during sinus tachycardia?

Answer 1

Sinus tachycardia:

1. Sinus tachycardia refers to a faster-than-usual heart rhythm.
2. Sinus rhythm during sinus tachycardia occurs at a heart rate above the normal for a particular age.
3. Generally, in the pre-operative period, this could be the outcome of stress, surgical stimulation, pain, anaemia, hypovolemia, fever, medications, or a high catecholamine state.
4. The treatment is fully dependent on the underlying cause of the disease.
5. Prolonged duration of sinus tachycardia could impair diastolic filling time, restrict ventricular preload, and risk cardiac output.
6. Children who are at risk of hemodynamic decompensation include those with that notable levels of diastolic dysfunction or ventricular hypertrophy.
