Tahhükardiale

Tahhükardiale is a term that describes a specific type of cardiac rhythm abnormality. It refers to a heart rate that is abnormally slow, often below 60 beats per minute in adults, but with a distinct pattern in the electrical activity of the heart as seen on an electrocardiogram (ECG). This pattern typically involves a regular rhythm but at a reduced rate, distinguishing it from other forms of bradycardia such as sinus arrhythmia or heart block.

The underlying causes of tahhükardiale can be varied. It may be a normal physiological response in well-conditioned athletes during rest, where a lower heart rate indicates greater cardiac efficiency. However, it can also be a symptom of underlying medical conditions, including hypothyroidism, electrolyte imbalances, certain medications (such as beta-blockers or calcium channel blockers), or increased intracranial pressure. In some cases, damage to the heart's natural pacemaker, the sinoatrial (SA) node, can lead to this condition.

Diagnosis of tahhükardiale relies on a combination of clinical assessment and ECG findings. A doctor will review the patient's medical history, current medications, and symptoms, which can include fatigue, dizziness, or fainting. The ECG provides objective evidence of the slow heart rate and its regular pattern. Treatment strategies depend on the cause and the presence of symptoms. If it is a physiological adaptation or asymptomatic, no intervention may be necessary. However, if it is symptomatic or caused by a treatable underlying condition, addressing the root cause is crucial. In severe cases where the heart rate is dangerously low and causing significant symptoms, a pacemaker may be considered to regulate the heart rhythm.
