When Is an Electrocardiogram Necessary?
An electrocardiogram is necessary in various clinical scenarios to evaluate heart health or diagnose specific cardiac conditions. It is commonly ordered when a patient exhibits symptoms such as chest pain, shortness of breath, dizziness, palpitations, or fainting, which could suggest heart-related issues. An ECG may also be required for patients with a history of heart disease, to monitor their condition and the effectiveness of treatments. Additionally, it's often part of a routine physical examination in older adults, those with risk factors for heart disease, or in individuals undergoing surgery to ensure the heart is healthy enough for the procedure.
Physicians may also use ECGs for preventive purposes or to screen for potential hidden heart conditions in asymptomatic individuals, especially if they have a family history of heart disease, diabetes, or other risk factors. In athletes, ECGs can be used to check for abnormalities that are sometimes found in physically active individuals and to prevent incidents of sudden cardiac death during strenuous activities.
