The most common causes of left ventricular hypertrophy are aortic stenosis, aortic regurgitation, hypertension, cardiomyopathy and coarctation of the aorta. There are several ECG indexes, which generally have high diagnostic specificity but low sensitivity.

Findings: STE of ≥ 1mm in aVR during stress testing predicted LMCA or ostial LAD stenosis with sensitivity 75%, specificity 81% and overall accuracy 80%. During stress testing i.e. exercise ECG, exercise is used to make the heart work hard and beat fast while an EKG is done. If exercise can't be done, you'll be given medicine to make your heart work hard and beat faster [2] . An electrocardiogram (EKG) measures your heart's electrical activity. Find out what an abnormal EKG means and understand your treatment options.

METHODS AND RESULTS: Among 5526 patients who underwent vasodilator stress single photon emission computed tomography (SPECT), 49 (0.9%) had normal images but ischemic ECG changes. Normal and Abnormal Findings from Exercise Stress ECG, Post-Exercise Echocardiography and Angiography Studies in a Series of Hypertensive and Normotensive … The Treadmill Stress ECG test will end when you become too tired to continue further or when you experience any symptoms like dizziness, shortness of breath or chest pain. You should aim to reach you peak heart rate or proceed with the test till your Stress ECG … Stress electrocardiographic (ECG) ST-segment depression is a prognostic marker of adverse cardiac outcomes in coronary artery disease. However, use of concurrent stress echocardiography (ECHO) has lead to concordant and discordant findings on stress electrocardiogram during stress studies.
