Final answer:
When treating a stable persistent tachyarrhythmia with a heart rate over 150 bpm, look for symptoms such as dizziness, shortness of breath, lightheadedness, rapid pulse, and chest pain. If no symptoms are present, examine underlying causes for appropriate treatment options.
Step-by-step explanation:
If it is stable persistent tachyarrhythmia (usually over 150 bpm), five symptoms to look for that can guide treatment are:
- Dizziness
- Shortness of breath
- Lightheadedness
- Rapid pulse or heart palpitations
- Chest pain or fainting (syncope)
If none of these symptoms are present, it's important to look at the underlying causes next which may include fever, anemia, hypoxia, hyperthyroidism, hypersecretion of catecholamines, cardiomyopathies, valve disorders, or acute exposure to radiation. The treatment plan would depend on the identified underlying cause and may involve medications, implantable cardioverter defibrillators, ablation, or surgery.
