Hypertension can be indicated by certain patterns on an electrocardiogram (ECG), which assist in diagnosing and evaluating cardiac conditions. Generally, an ECG can reflect alterations in the heart's electrical activity due to hypertension, although these changes do not always definitively indicate hypertension. Hypertension may result in left ventricular hypertrophy (LVH) on an ECG, a consequence of the heart's left ventricle needing to exert more force against elevated blood pressure over time, leading to the enlargement of cardiac muscle cells. ECG signs of LVH include, but are not limited to, a deeper S wave and a higher R wave, particularly in chest leads V5 and V6. Moreover, hypertension can also cause tachycardia or bradycardia, arrhythmias, changes in the ST segment, and inverted T waves. These alterations may be associated with increased cardiac workload, myocardial ischemia, or other cardiovascular complications. Regular ECG monitoring is essential for patients with a history of hypertension to promptly detect and manage potential cardiac issues. Controlling blood pressure, maintaining a healthy lifestyle, and adhering to prescribed medication are crucial for the prevention and management of hypertension and its associated complications. Abnormal ECG findings warrant immediate medical consultation and adjustment of the treatment plan under a physician's guidance.
