rütmihäiretele

Rütmihäiretele, also known as arrhythmias, refer to irregular heart rhythms. This means the heart beats too fast (tachycardia), too slow (bradycardia), or with an irregular pattern. These deviations from the normal heart rate and rhythm can affect the heart's ability to pump blood effectively to the rest of the body.

Causes of rütmihäiretele are diverse. They can stem from issues within the heart's electrical system, such as problems with the natural pacemaker or the conduction pathways. Other contributing factors include underlying heart conditions like coronary artery disease, heart failure, or valve problems. Non-cardiac causes can also play a role, including electrolyte imbalances, thyroid disorders, stress, certain medications, alcohol consumption, and excessive caffeine intake.

Symptoms associated with rütmihäiretele vary greatly depending on the type and severity. Some individuals may experience no symptoms at all, while others might feel palpitations, a fluttering sensation in the chest, dizziness, lightheadedness, shortness of breath, chest pain, or even fainting (syncope). In severe cases, rütmihäiretele can lead to more serious complications like stroke or sudden cardiac arrest.

Diagnosis typically involves a medical history, physical examination, and diagnostic tests. An electrocardiogram (ECG or EKG) is the primary tool used to record the heart's electrical activity and identify rhythm abnormalities. Other tests may include Holter monitoring (a portable ECG worn for 24-48 hours), event monitors, echocardiograms, or electrophysiology studies.

Treatment for rütmihäiretele is tailored to the specific type of arrhythmia, its cause, and the patient's symptoms and overall health. Options may include lifestyle modifications, medications to control heart rate or rhythm, or procedures like electrical cardioversion or catheter ablation. In some instances, a pacemaker or implantable cardioverter-defibrillator (ICD) may be necessary.
