14 Possible Causes for Electrocardiogram Change, ST Elevation, Tachycardia during Pain Episodes

  • Variant Angina Pectoris

    Ventricular premature beats, ventricular tachycardia and one episode of ventricular fibrillation were recorded.[] Changes were quantified by subtracting baseline electrocardiograms from those obtained during ischemia.[] The mean daily number of ST elevation in group 1 was similar to that in group 2 (4.8 /- 5.1 vs 4.1 /- 4.6; p not significant).[]

  • Coronary Atherosclerosis

    No ischemic changes on the electrocardiogram were noted for either patient.[] Transient ST-segment depression and chest pain detected during ambulatory monitoring were usually associated with tachycardia ( Figure 3 ).[] Although most will recognise the typical ECG features of ST elevation myocardial infarction, the significance of ST elevation in lead aVR may not always be appreciated.[]

  • Ventricular Tachycardia

    Understanding of the initial electrocardiographic pattern and subsequent changes can lead to early intervention and an improved outcome.[] 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.[] Since symptoms had continued, 24-hour Holter monitoring was ordered at our facility and results revealed huge ST elevation and polymorphic ventricular tachycardia.[]

  • Paroxysmal Supraventricular Tachycardia

    The sequence can also be inverse, changing from atrial fibrillation to nodal reentrant tachycardia ( Figure 9 ). Figure 9.[] Abstract During episodes of paroxysmal supraventricular tachycardia (PSVT), electrocardiograms frequently show ST-segment depressions, and patients may experience typical[] ) adult patients who are comatose after OHCA of suspected cardiac origin but without ST elevation on ECG (Class IIa, LOE B-NR).updated for 20152015Cardiovascular CareCoronary[]

  • Wolff-Parkinson-White Syndrome

    The mechanism of the electrocardiogram changes was considered to be caused by the two drugs synergistic sodium channel blocking effects.[] A child old enough to express himself may complain of chest pain, palpitations, dizziness, lethargy and difficulty in breathing during episodes of tachycardia.[] Immediately following this, her rhythm changed to wide QRS irregular tachycardia without hemodynamic compromise.[]

  • Bradyarrhythmia

    Other symptoms experienced during an episode of SVT include dizziness, shortness of breath, chest pain, and light-headedness.[] ACC/AHA guidelines for the management of patients with ST-elevation myocardial infarction-executive summary.[] Of particular importance are treatment of hypoxemia and hypotension, early diagnosis and treatment of ST-elevation myocardial infarction (STEMI) (Class I, LOE B) and therapeutic[]

  • Preexcitation Syndrome

    , shape changing complexes in a young individual.[] […] or irregularly) Shortness of breath A physical exam done during a tachycardia episode will show a heart rate faster than 100 beats per minute.[] Pathologic ST-segment elevation beyond 1 mm (double arrow) with pathologic Q waves (arrow) in lead V 3.[]

  • Lown-Ganong-Levine Syndrome

    In cases of underlying structural heart disease or coronary artery disease, episodes of tachycardia may induce cardiac stress and produce symptoms of chest pain or possibly[] ( Osborn wave, ST elevation, ST depression ) Cardiomegaly Ventricular hypertrophy ( Left, Right / Cor pulmonale ) · Atrial enlargement ( Left, Right ) Other Cardiac fibrosis[] However, diagnosis requires the presence of this pattern in more than one corresponding lead, myocardial infarctions with pathological Q waves are referred to as ST elevation[]

  • Holiday Heart Syndrome

    These tests not only confirm the diagnosis but also identifies other pathological changes of the heart.[] During an episode, you may experience symptoms such as: a pounding or fluttering heartbeat ( heart palpitations ) feeling light-headed or dizzy shortness of breath chest pain[] , Choose the correct items: (there are 2 correct answers) This patient is stable and can safely be transported by the BLS crew alone This patient's ekg shows significant ST[]

  • Cardiac Asthma

    Heart failure will be confirmed through electrocardiograms (EKG), cardiac stress tests, and imaging tests such as echocardiogram (an ultrasound of the heart) and CT scans.[] During the acute episode, the patient may experience chest pain, usually caused by myocardial ischemia.[] elevated myocardial infarction) in 40, CAP in 38, anemia in 20, and associated PE in 11.[]
