Positive T wave overshoot as a sign of ventricular enlargement.

Q wave T wave vector discordance in hypertrophic cardiomyopathy: septal hypertrophy and strain pattern.

Hypertrophic cardiomyopathy is a common cause of prominent non-infarctional Q waves. A retrospective analysis of previously published cases confirmed a characteristic Q wave T wave vector discordance in hypertrophic cardiomyopathy. In 41 of 44 cases with predominant Q waves (as part of QS or Qr complexes where Q wave amplitude exceeded R wave height), the T wave was positive, and in all cases w...

گزارش موردی نادر از دو شاخه شدن موج T در زمینه طولانی شدن قطعه QT ناشی از سندرم حاد کرونری

Introduction: Bifid T waves are seen in healthy young children and alcoholic adults. They also occur in certain pathological conditions, including organic heart diseases, and the central nervous system disorder. Myocardial ischemia can affect T wave morphology in a variety of ways one of which is t wave change as bifid t wave observed in QTc prolongation forms oc-curring in acute coronary event...

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

Detection of Cardiac Hypertrophy by RVM and SVM Algorithms

The meaning of the hypertropy word is the increasing size.Heart hypertropy is symptoms of increase the thickness of the heart muscle that the left ventricular hypertrophy of them is the most common.The causes of hypertrophy heart disease are high blood pressure , aortic valve stenosis and sport activities respectively. Assessment of that by using ECG signal analysis is essential Because the ris...

بررسی اثر کاهش حجم بر روی پارامترهای دیاستولیک اکو کاردیوگرافی در بیماران همودیالیزی

Background: Cardiovascular problems including arterial hypertension, coronary artery diseases, congestive heart failure are prevalent among chronic hemodialyzed patients. Ultrafiltration of hemodialyzed patient's serum, which culminating in intravascular volume reduction, is frequently used during hemodialysis. One of the restrictions of the echocardiographic evaluation of the diastolic heart f...
