aritmiákot

Aritmiákot, also known as arrhythmias, are irregularities in the heart's rhythm. This means the heart may beat too fast, too slow, or with an inconsistent pattern. While some arrhythmias are harmless and may not even be noticed, others can be serious and lead to significant health problems. The heart's electrical system controls the timing of its beats, and disruptions to this system can cause arrhythmias. Common causes include underlying heart disease, electrolyte imbalances, certain medications, stress, and lifestyle factors like excessive caffeine or alcohol consumption. Symptoms can vary widely and may include palpitations (a feeling of a racing or fluttering heart), shortness of breath, dizziness, chest pain, and fainting. Diagnosis typically involves an electrocardiogram (ECG or EKG) to record the heart's electrical activity. Other tests, such as Holter monitoring or an event recorder, may be used for longer-term assessment. Treatment depends on the type and severity of the arrhythmia and can range from lifestyle changes and medication to procedures like cardioversion or the implantation of a pacemaker or defibrillator.
