The symptoms of südameveresoonkond may include a sudden blackout, dizziness, lightheadedness, or a feeling of impending faintness before losing consciousness. Some individuals may also experience palpitations, chest discomfort, or shortness of breath. Unlike fainting due to other causes, such as standing up too quickly, cardiac syncope often occurs without clear triggers and may be accompanied by warning signs like irregular heartbeat.
Common causes of südameveresoonkond include arrhythmias (abnormal heart rhythms), such as ventricular tachycardia or atrial fibrillation, structural heart diseases like aortic stenosis or hypertrophic cardiomyopathy, or severe bradycardia (slow heart rate). Other factors, such as electrolyte imbalances, medications affecting heart function, or underlying conditions like heart failure, can also contribute. In some cases, the cause may remain unclear, classified as unexplained syncope.
Diagnosis typically involves a thorough medical evaluation, including a detailed patient history, physical examination, and diagnostic tests. Electrocardiogram (ECG), Holter monitoring, or an electrophysiology study may be used to detect abnormal heart rhythms. Additional imaging studies, such as an echocardiogram or stress test, can help identify structural heart issues. In ambiguous cases, tilt-table testing or event recorders may be employed to monitor symptoms over time.
Treatment depends on the underlying cause. For arrhythmias, medications, pacemakers, or implantable cardioverter-defibrillators (ICDs) may be prescribed. Structural heart diseases often require surgical or catheter-based interventions. Lifestyle modifications, such as avoiding triggers like dehydration or excessive alcohol, and managing chronic conditions like hypertension can also reduce the risk of recurrence. Immediate medical attention is crucial, as südameveresoonkond can sometimes indicate life-threatening conditions that require prompt intervention.
