973 Possible Causes for Electrocardiogram Change, Tachycardia during Pain Episodes, Wide QRS Complex

  • Ventricular Tachycardia

    Understanding of the initial electrocardiographic pattern and subsequent changes can lead to early intervention and an improved outcome.[ncbi.nlm.nih.gov] If your heart rate during a ventricular tachycardia episode is extremely rapid or continues for several seconds, you may experience some or all of these symptoms.[uabmedicine.org] KEYWORDS: Algorithms; VT score; Ventricular tachycardia; Wide QRS complex tachycardia[ncbi.nlm.nih.gov]

  • Wolff-Parkinson-White Syndrome

    The mechanism of the electrocardiogram changes was considered to be caused by the two drugs synergistic sodium channel blocking effects.[ncbi.nlm.nih.gov] A child old enough to express himself may complain of chest pain, palpitations, dizziness, lethargy and difficulty in breathing during episodes of tachycardia.[symptoma.com] We report a 68-year-old man who presented with heart failure and atrial fibrillation (AF) with rapid ventricular response and wide QRS complexes.[ncbi.nlm.nih.gov]

  • Morbid Obesity

    BACKGROUND: There are indications that pain perception is altered in patients with obesity, which complicates postoperative pain treatment. An essential part for adequate pain treatment is the capacity of the patient to grade pain. OBJECTIVES: The aim of this study was to identify the differences in pain[…][ncbi.nlm.nih.gov]

  • Myocardial Infarction

    A case was diagnosed as AMI if two out of the three criteria (clinical symptoms, electrocardiogram changes and raised enzyme levels) were positive.[dx.doi.org] , electrocardiogram changes indicative of ischemia (ST segment elevation or depression), or coronary artery intervention (e.g., coronary angioplasty); or (2) pathologic findings[doi.org] […] typical increase and gradual decrease of biochemical markers of myocardial necrosis and at least 1 of the following: ischemic symptoms, development of pathologic Q waves on electrocardiogram[doi.org]

  • Acute Myocardial Infarction

    But it was difficult to differentiate those two diseases because the TC-like findings; such as the electrocardiogram (ECG) changes and left ventricular wall motion abnormality[ncbi.nlm.nih.gov] (ECG or EKG) – a test that looks at the heart's electrical activity and rhythm; the diagnosis of a heart attack may be made by changes seen on an electrocardiogram and by[labtestsonline.org] Electrocardiography and cardiac troponin (cTn) now form the diagnostic cornerstones of clinical assessment. 1,2 Often, an electrocardiogram (ECG) alone is insufficient to[radcliffecardiology.com]

  • Third Degree Atrioventricular Block

    There is a wide spectrum of changes in the resting electrocardiograms of athletes.[ncbi.nlm.nih.gov] ECG features of 3rd degree AV block On the ECG P-waves have no relation to the QRS complexes. The QRS complexes may be normal or wide.[ecgwaves.com] If the block is below the bifurcation of the His bundle, the QRS complexes are wide.[en.my-ekg.com]

    During the ECST, the patient's electrocardiogram (EKG), heart rate, heart rhythm, and blood pressure are continuously monitored.[medicinenet.com] The signal that originated in the ventricle can be distinguished from a normal signal by its wide QRS complex and lack of a P wave.[wisegeek.com] Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular[ncbi.nlm.nih.gov]
