tachykardii
Tachykardii, commonly referred to as tachycardia, is a condition characterized by an abnormally fast heart rate. In adults, a resting heart rate above 100 beats per minute is generally considered tachycardic. Tachycardia can be a normal response to exercise, stress, fever, or dehydration, or it can reflect an underlying medical condition. When rapid heartbeats occur, the heart may not have enough time to fill properly, reducing cardiac efficiency.
Tachycardia can be categorized as sinus tachycardia, where the sinus node drives the faster rate, or as
Causes are broad and include physiological factors (exercise, fever, anxiety, pain, sympathetic stimulation) and pathological conditions
Diagnosis relies on clinical assessment and an electrocardiogram (ECG). Additional testing may include blood tests, echocardiography,
Management depends on stability, rhythm type, and underlying cause. In unstable patients, urgent synchronized electrical cardioversion
Prognosis varies with the cause; tachycardia due to transient physiological factors is usually self-limited, while tachyarrhythmias
