Strain pattern

Strain pattern refers to the specific changes in the heart's electrical activity, often seen on an electrocardiogram (ECG), that suggest a person may have or is at risk of developing cardiovascular disease. It is often associated with hypertension, coronary artery disease, and cardiomyopathy.

Overview

Strain pattern is characterized by ST segment depression and T wave inversion in the lateral leads of an ECG. It is often seen in patients with left ventricular hypertrophy (LVH), a condition where the left ventricle of the heart becomes thickened. However, it can also be seen in other conditions such as hypertrophic cardiomyopathy and coronary artery disease.

Causes

Strain pattern can be caused by a number of conditions, including:

• Hypertension: High blood pressure can cause the heart to work harder, leading to left ventricular hypertrophy and strain pattern on ECG.
• Coronary artery disease: This condition, which involves narrowing of the coronary arteries, can also lead to strain pattern.
• Cardiomyopathy: This refers to diseases of the heart muscle, which can cause strain pattern on ECG.

Diagnosis

Strain pattern is typically diagnosed through an electrocardiogram (ECG). The ECG will show specific changes in the heart's electrical activity, such as ST segment depression and T wave inversion in the lateral leads.

Treatment

Treatment for strain pattern involves addressing the underlying cause. This may involve medications to control high blood pressure, procedures to improve blood flow to the heart in cases of coronary artery disease, or treatments to manage heart muscle disease.
