26 Possible Causes for Ejection Fraction Decreased, Short PR Interval

  • Acute Myocardial Infarction

    Bedside echocardiography disclosed akinesis of the anterior and lateral walls, apex, and anterior septum with severely decreased left ventricular ejection fraction of 30%.[ncbi.nlm.nih.gov]

  • Myocardial Infarction

    After start of the GFD, abnormal left ventricular dimensions, and diminished cardiac function, including decreased ejection fraction, can improve markedly and may even be[dx.doi.org] Preservation of myocardial contractile function is paramount, and left venticular ejection fraction should be monitored with short-term and long-term echocardiographic evaluation[clinicaladvisor.com] PCI, CABG, or fibrinolysis), should decrease myocardial necrosis and alleviate the symptoms associated with MI.[clinicaladvisor.com]

  • Fabry Disease

    In 2004, echocardiography showed a moderate reduction in LV contractility (ejection fraction, 42%).[circ.ahajournals.org] General physicians and cardiologists should consider the diagnosis of FD in patients with LVH, cardiomyopathy, and conduction abnormalities, including short PR intervals and[ncbi.nlm.nih.gov] Pochis WT, Litzow JT, King BG, Kenny D (1994) Electrophysiologic findings in Fabry’s disease with a short PR interval.

  • Ebstein Malformation

  • Anterior Myocardial Infarction

    Conventional ultrasound: Acute phase The global LV systolic function directly after the myocardial infarction was moderately decreased with a left ventricular ejection fraction[specklepedia.com] At the fourth day, while ST elevations returned to baseline, short PR interval and delta waves were observed on the ECG.[ncbi.nlm.nih.gov]

  • Right Bundle Branch Block

  • Incessant Infant Ventricular Tachycardia

    However, an echocardiogram on day of life 33 showed a significant decrease in the ejection fraction, below 20%, and the decision was made to proceed to an electrophysiology[innovationsincrm.com] Note: Very short PR interval ( 100 ms). Slurred upstroke to the QRS complexes the delta wave.[lifeinthefastlane.com] Studies show that 40-50% of patients with septic shock develop myocardial depression (defined as a decrease in left ventricular ejection fraction).[signavitae.com]
