DIAGNOSTIC TESTS & INTERPRETATION navigator

Lab navigator

None, except to assess electrolytes and drug levels where appropriate

Imaging navigator

Pathological Findings navigator

Pathology depends on substrate, including coronary artery disease, any cause of myocardial fibrosis (cardiomyopathy, trauma), fibroadipose infiltration of the myocardium (arrhythmogenic RV dysplasia), inflammatory disease (myocarditis, sarcoidosis), or none (RV outflow tract tachycardia, idiopathic left VT, Brugada syndrome).

FOLLOW-UP RECOMMENDATIONS

Patient Monitoring navigator

DIET navigator

Choose diet appropriate for underlying heart disease (low-cholesterol if coronary artery disease, low-sodium if CHF, calorie-restricted if diabetic).

PATIENT EDUCATION navigator

PROGNOSIS navigator

Outcome depends on underlying heart disease and comorbid conditions. For patients with VT and a structurally normal heart, prognosis is excellent (RV outflow tract and idiopathic LV tachycardias).
