What is the prognosis for heart rhythm disorders?
While most heart dysrhythmias can be treated and controlled, ventricular fibrillation or tachycardia can be fatal. Their recognition and treatment are true emergencies, and there is no guarantee that sudden cardiac death can be reversed.
For all other rhythm abnormalities, there may be time to make the diagnosis and design a treatment plan. The goal is to minimize the effect that the dysrhythmia has on daily activity and quality of life.
Can heart rhythm disorders be prevented?
For those with rapid palpitations that are intermittent, avoiding stimulants like alcohol, caffeine, over-the-counter cold medications, and illicit drugs are important preventive measures.
