Validation and Assessment of Novel Morphology-Voltage-P-wave Score for Diagnosing Left Ventricular Diastolic Dysfunction in Patients With Hypertension

This study is validating a new scoring system that uses ECG (electrocardiogram) patterns to detect a heart condition called left ventricular diastolic dysfunction — which means the heart muscle has trouble relaxing properly — in people with high blood pressure. Researchers want to see if this score can help diagnose the condition without needing more invasive tests. **You may be eligible if...** - You have been diagnosed with essential (primary) high blood pressure - You are able to have an ECG and echocardiogram (heart ultrasound) **You may NOT be eligible if...** - You have secondary or treatment-resistant hypertension - Your heart pumping function (ejection fraction) is below 55% - You have congenital heart disease, coronary artery disease, valve disease, or kidney disease - You have a bundle branch block or irregular heart rhythm - You have other forms of heart muscle disease Talk to your doctor to see if this trial is right for you.
