rytminnättömyys

Rytminnättömyys, also known as arrhythmia, is a term used to describe irregular heart rhythms. This can manifest as a heart beating too fast (tachycardia), too slow (bradycardia), or with an irregular pattern. The electrical system of the heart is responsible for coordinating its contractions, and disruptions in this system can lead to arrhythmias.

Causes of arrhythmias are varied. They can range from lifestyle factors such as stress, caffeine, and alcohol consumption to underlying medical conditions like heart disease, high blood pressure, thyroid problems, and electrolyte imbalances. Certain medications and genetic predispositions can also contribute to the development of irregular heartbeats.

Symptoms of an arrhythmia can differ greatly among individuals and depend on the type and severity of the condition. Some people may experience no noticeable symptoms, while others might feel palpitations, a racing heart, skipped beats, dizziness, shortness of breath, chest pain, or even fainting.

Diagnosis typically involves a medical history, physical examination, and an electrocardiogram (ECG or EKG) to record the heart's electrical activity. Further tests, such as Holter monitoring or an event recorder, may be used to capture irregular rhythms that occur intermittently.

Treatment for arrhythmias aims to restore a normal heart rhythm, control the heart rate, and prevent complications like stroke. Options include lifestyle modifications, medications to regulate heart rhythm or rate, and in some cases, procedures like cardioversion, catheter ablation, or the implantation of a pacemaker or defibrillator. Early diagnosis and appropriate management are important for maintaining heart health and quality of life.
