AMBULATORY ELECTROCARDIOGRAPHY |
|
Class I |
Palpitations, syncope, dizziness |
|
Class II |
Shortness of breath, chest pain, or fatigue (not otherwise explained, episodic, and strongly suggestive of an arrhythmia as the cause because of a relation of the symptom with palpitation) |
|
Class III |
Symptoms not reasonably expected to be due to arrhythmia |
|
ELECTROPHYSIOLOGIC STUDY |
|
Class I |
|
|
Class II |
Patients with clinically significant palpitations, suspected to be of cardiac origin, in whom symptoms are sporadic and cannot be documented; studies are performed to determine the mechanisms of arrhythmias, to direct or provide therapy, or to assess prognosis |
|
Class III |
Patients with palpitations documented to be due to extracardiac causes (e.g., hyperthyroidism) |
|
ECHOCARDIOGRAPHY |
|
Class I |
Arrhythmias with evidence of heart disease |
|
Family history of genetic disorder associated with arrhythmias |
|
Class II |
Arrhythmias commonly associated with, but without evidence of, heart disease |
|
Atrial fibrillation or flutter |
|
Class III |
Palpitations without evidence of arrhythmias |
|
Minor arrhythmias without evidence of heart disease |
