ecg for pulmonary hypertension

Pulmonary arterial hypertension (PAH) is a form of heart disease characterized by elevated pressure in the right ventricle, which can impair the heart's function. The electrocardiogram (ECG) is a crucial diagnostic tool for PAH, providing insights into the heart's electrical activity and the condition of the myocardium. However, an ECG is not sufficient for a direct diagnosis of PAH; it is typically used in conjunction with other diagnostic methods, including chest X-rays, echocardiograms, and blood tests.

In ECG readings, PAH may manifest specific patterns of abnormalities. The most frequent of these is right ventricular hypertrophy (RVH), a condition resulting from the right ventricle's prolonged exposure to excessive pressure. Additionally, right bundle branch block (RBBB) may be observed, which is an electrical conduction defect in the heart associated with PAH. In more severe cases, atrial fibrillation (AF), a type of arrhythmia that can further deteriorate heart function, may occur.

For individuals suspected of having PAH, a comprehensive physical examination and additional diagnostic tests are essential beyond an ECG. Once a diagnosis is confirmed, patients should follow a standardized treatment plan under medical supervision to manage the disease and prevent complications. It is also important for patients to adopt lifestyle modifications, such as quitting smoking, moderating alcohol intake, maintaining a healthy diet, and engaging in regular physical activity, to alleviate the strain on the heart and enhance their quality of life.
