Ventricular tachycardia in coronary artery disease.
Ventricular arrhythmias are important contributors to morbidity and mortality in patients with coronary artery disease. Ventricular fibrillation accounts for the majority of deaths occurring in the acute phase of ischemia, whereas sustained, monomorphic ventricular tachycardia due to reentry generated in the scar tissue develops most often in the setting of healed myocardial infarction, especia...
متن کاملMyocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]
Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...
متن کاملNonsustained ventricular tachycardia in coronary artery disease: relation to inducible sustained ventricular tachycardia. MUSTT Investigators.
BACKGROUND Many physicians believe that electrocardiographic characteristics of nonsustained ventricular tachycardia correlate with the risk for sudden death in survivors of myocardial infarction. Sustained ventricular tachycardia induced by programmed electrical stimulation has also been shown to predict sudden death. OBJECTIVE To determine whether electrocardiographic characteristics of spo...
متن کاملAthens QRS Score as a Predictor of Coronary Artery Disease in Patients With Chest Pain and Normal Exercise Stress Test
BACKGROUND The diagnostic value of the Athens QRS score to detect obstructive coronary artery disease CAD in patients with otherwise normal exercise stress test remains unclear. METHODS AND RESULTS We analyzed 458 patients who underwent exercise stress test with or without myocardial perfusion imaging within 2 months of coronary angiography from 2008 to 2011. Patients (n=173) with abnormal st...
متن کاملThe normal electrocardiogram as a predictor of left ventricular function in patients with coronary artery disease.
Fifty-five consecutive patients with a normal resting electrocardiogram and coronary artery disease were examined to determine left ventricular function. Fifty-two (95%) had no evidence of left ventricular asynergy; 3 patients had only mild hypokinesis. Of this group of patients, 25 (47%) had one vessel disease, 17 (30%) had two vessel disease, and 13 (23%) had three vessel disease. Significant...
