Takikardi

Takikardi, also known as tachycardia in English, is a medical condition characterized by an abnormally rapid heart rate. Typically, a heart rate exceeding 100 beats per minute in adults is considered tachycardia, although the specific threshold may vary depending on age and individual health factors.

There are several types of tachycardia, classified based on their origin within the heart. Supraventricular tachycardia (SVT) originates above the ventricles, while ventricular tachycardia begins in the lower chambers of the heart. Other forms include sinus tachycardia, which results from an increased rate of electrical impulses in the sinoatrial node.

Common causes of tachycardia include stress, anxiety, excessive caffeine or stimulant intake, fever, anemia, electrolyte imbalances, and underlying heart diseases such as ischemia or cardiomyopathy. It can also be triggered by certain medications or drug use.

Symptoms associated with tachycardia vary; some individuals remain asymptomatic, while others may experience palpitations, dizziness, shortness of breath, chest pain, or fainting. In severe cases, it can lead to complications like heart failure or stroke.

Diagnosis involves clinical evaluation, electrocardiogram (ECG), Holter monitoring, and sometimes additional tests such as electrophysiological studies. Treatment depends on the type and severity of the tachycardia and may include medications like beta-blockers or antiarrhythmics, lifestyle modifications, or procedural interventions such as catheter ablation.

Effective management aims to control heart rate, prevent recurrence, and address underlying causes. Prompt medical attention is recommended if tachycardia symptoms are severe or persistent to reduce the risk of complications.
