Sinus tachycardia can be caused by a variety of factors, and the nurse would consider several potential causes when assessing a client with this dysrhythmia. These may include:
1. Anxiety or stress
2. Fever or infection
3. Dehydration or electrolyte imbalances
4. Hypovolemia (low blood volume)
5. Medications such as stimulants or bronchodilators
6. Thyroid disease
7. Cardiac disease, such as heart failure or myocardial infarction
8. Pulmonary embolism or other respiratory conditions
The nurse would assess the client's medical history, current medications, vital signs, and other symptoms to help determine the underlying cause of the sinus tachycardia, and to develop an appropriate plan of care.
