Description: Tachyarrhythmia is a heart rhythm disorder characterized by an abnormally fast heart rate, typically exceeding 100 beats per minute at rest. This phenomenon can be caused by various conditions, including heart problems, electrolyte imbalances, or side effects of medications. Tachyarrhythmia can manifest in different forms, such as atrial fibrillation, ventricular tachycardia, or supraventricular tachycardia, each with its own characteristics and associated risks. Detection of tachyarrhythmia is commonly performed through an electrocardiogram (ECG), which allows visualization of the heart’s electrical activity and diagnosis of the specific type of arrhythmia. Tachyarrhythmia may be asymptomatic in some cases, but in others, it can cause symptoms such as palpitations, dizziness, shortness of breath, or chest pain. The importance of recognizing and treating tachyarrhythmia lies in its potential to lead to serious complications, such as stroke or cardiac arrest, making it a crucial topic in cardiology.
