tachikardi

Tachykardia, also known as tachycardia, is a medical condition characterized by an abnormally rapid heart rate. The normal resting heart rate for adults is typically between 60 and 100 beats per minute (bpm). Tachycardia is defined as a heart rate exceeding 100 bpm in adults. This condition can be further classified based on the underlying cause and the presence or absence of symptoms.

Tachycardia can be caused by various factors, including physical exertion, stress, anxiety, certain medications, and underlying medical conditions such as hyperthyroidism, anemia, or electrolyte imbalances. It can also be a symptom of more serious conditions like heart disease, arrhythmias, or infections.

Symptoms of tachycardia can vary widely and may include palpitations, shortness of breath, chest pain, dizziness, and fatigue. In some cases, tachycardia may be asymptomatic, particularly in young, healthy individuals.

Diagnosis of tachycardia typically involves a physical examination, electrocardiogram (ECG), and sometimes additional tests to identify the underlying cause. Treatment depends on the underlying cause and may include lifestyle modifications, medications, or procedures such as cardioversion or ablation.

It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment, as tachycardia can sometimes indicate a more serious underlying condition.
