aritmiáról

Aritmia is a medical term referring to an irregular heartbeat. This means the heart beats too fast, too slow, or with an irregular rhythm. It can be a symptom of various underlying heart conditions or can occur independently.

There are many types of arrhythmias, broadly categorized as bradycardia (slow heart rate) and tachycardia (fast heart rate). Examples include atrial fibrillation, where the upper chambers of the heart beat chaotically, and ventricular tachycardia, a potentially life-threatening condition originating in the lower chambers. Other common arrhythmias include premature atrial contractions (PACs) and premature ventricular contractions (PVCs), which are extra, early heartbeats.

Symptoms of arrhythmia can vary widely. Some individuals may experience no symptoms at all, while others might notice palpitations, a fluttering sensation in the chest, dizziness, shortness of breath, chest pain, or fainting. The severity of symptoms often depends on the type of arrhythmia, its duration, and the individual's overall health.

Diagnosis typically involves a physical examination, an electrocardiogram (ECG or EKG) to record the heart's electrical activity, and sometimes more advanced monitoring such as Holter monitors or event recorders. Echocardiograms and other imaging tests may be used to assess the heart's structure and function.

Treatment for arrhythmia depends on the specific type, its cause, and the patient's symptoms. Options range from lifestyle modifications and medication to procedures like cardioversion, catheter ablation, or the implantation of pacemakers or defibrillators. In some cases, no treatment is necessary if the arrhythmia is benign and asymptomatic.
