Sinus Tachycardia in Children

Sinus tachycardia is an increase in the normal heart rate. It is very common in children and usually does not require treatment. In most cases, sinus tachycardia occurs with fever, agitation, or exercise. Increased thyroid activity or conditions such as anemia (low blood count) may also cause sinus tachycardia, although these are rare cases. In these cases, the tachycardia usually disappears once the underlying condition has been treated.

Respiratory sinus arrhythmia is most of the time a casual finding and the person who has it does not notice any symptoms. Only that, if you learn to take your pulse, you will notice how it oscillates according to your breathing. It is usually detected during an electrocardiogram for some other reason. Sinus bradycardia due to sinus disease can cause tiredness, inability to exert yourself, dizziness and even loss of consciousness (syncope). Sinus bradycardia does not cause death, but it can reduce the quality of life and when it causes loss of consciousness it can lead to major trauma (due to a sudden fall). Sinus tachycardia can be bothersome because the patient’s heartbeat feels very fast and the symptom it can cause is early fatigue. It can limit the patient’s ability to make efforts, not tolerating moderate or sometimes even low intensity efforts. We can conclude that sinus arrhythmias can reduce the quality of life of the patient, but do not imply a decrease in survival. You can also read: Just discipline in children. At Doctor Urgent Medical Care we understand that illness and injury can occur at any time. Contact us HERE How is sinus tachycardia diagnosed? The first diagnostic test to be performed is an electrocardiogram, which is performed directly in the doctor’s office and allows the electrical activity of the heart to be recorded on paper (for this purpose, wires are placed on the thorax and limbs and the cardiac electrical activity is recorded by means of a device known as an electrocardiograph). A very useful test in this type of arrhythmia is the Holter, which allows continuous electrocardiographic recording for 24 h or more. The patient carries out his normal life during the time he has this device. In certain specific cases, it may be necessary to use devices such as the T-shirt Holter, which allows the heart rhythm to be recorded for several weeks. If there is suspicion of sinus node disease causing bradycardias or very occasional sinus pauses, but with important symptoms (basically loss of consciousness), an insertable Holter can be used, which is a small electronic device that is inserted in the thorax under the skin and allows the heart rhythm to be recorded for 2-3 years.
