Tachycardia

Tachycardia: causes, symptoms and treatment

Tachycardia is the medical term used to describe a condition in which the heart rate becomes unusually fast. This condition is characterized by rapid heart rate that exceeds the normal rate for rest or physical activity. The term "tachycardia" comes from the Greek words "tachy-", which means "fast", and "cardia", which translates as "heart".

Tachycardia can be caused by various factors. One of the most common causes is stress or physical activity. During exercise or emotional stress, the body may increase its heart rate to provide additional blood flow to muscles and organs. However, in some cases, tachycardia can be a sign of serious medical problems, such as cardiac arrhythmias, thyroid disorders, heart failure, or even side effects of certain medications.

Symptoms of tachycardia may vary depending on its cause and the individual's characteristics. However, the most common symptoms are:

1. Rapid heartbeat or sensation of a fast heartbeat;
2. Irregular or asymmetrical pulse;
3. Feeling of heartbeat in the chest;
4. dizziness or fainting;
5. Feeling of shortness of breath or difficulty breathing;
6. Weakness or fatigue.

If you experience these symptoms, it is important to see your doctor for an accurate diagnosis and appropriate treatment. To diagnose tachycardia, your doctor may do a physical examination, including auscultation of the heart and taking your pulse, and order additional tests, such as an ECG (electrocardiogram) or a wearable heart rate monitor.

Treatment for tachycardia depends on its cause and severity. In some cases, lifestyle changes such as eliminating stress, limiting caffeine or alcohol intake, and exercising can help manage heart palpitations. More severe cases may require medications such as antiarrhythmics or beta blockers to normalize the heart rhythm.

In rare cases, when tachycardia is life-threatening or does not respond to conservative treatment, a procedure or surgery such as catheter ablation or pacemaker implantation may be required.

In general, the prognosis for patients with tachycardia depends on the cause and the effectiveness of treatment. Most cases of tachycardia can be successfully controlled and not treated

Tachycardia is a pathological increase in heart rate more than 10 times per minute during sinus rhythm at rest or during physical stress. Possible symptom of arrhythmia. In the absence of conduction disturbances, atrial fibrillation may also be accompanied by tachycardia. It usually occurs with increased activity of the vagus nerve and does not require treatment.
