64 Possible Causes for Electrocardiogram Change, Short PR Interval

  • 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.[oadoi.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]

  • Hypertrophic Cardiomyopathy

    Following conversion of atrial fibrillation to sinus rhythm, he had deep symmetrical T-wave changes on his electrocardiogram.[ncbi.nlm.nih.gov] BACKGROUND: Electrocardiogram is the initial test in the investigation of heart disease.[ncbi.nlm.nih.gov] This time, a new significant change in ECG and SPECT was identified.[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] Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography[ncbi.nlm.nih.gov] Immediately following this, her rhythm changed to wide QRS irregular tachycardia without hemodynamic compromise.[ncbi.nlm.nih.gov]

  • Preexcitation Syndrome

    , shape changing complexes in a young individual.[symptoma.com] The classic electrocardiogram in Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval and prolonged QRS duration in the presence of sinus rhythm with[ncbi.nlm.nih.gov] PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[medical-dictionary.thefreedictionary.com]

  • Lown-Ganong-Levine Syndrome

  • Fabry Disease

    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. Am J Cardiol 74:203–204 PubMed Google Scholar 64.[doi.org]

  • Pheochromocytoma

    BACKGROUND: Pheochromocytoma is an endocrine tumor that causes hypertension, facial pallor, and headache. Pheochromocytoma patients rarely present with acute heart failure or cardiogenic shock. METHOD: We discuss the case of a female patient with Takotsubo-pattern cardiomyopathy who presented with acute heart[…][ncbi.nlm.nih.gov]

  • Ebstein Malformation

    The classic WPW ECG pattern consists of : A short PR interval (rapid AV conduction through the accessory pathway) Delta wave (initial slow ventricular activation due to fiber[pedclerk.bsd.uchicago.edu] interval; may be normal/short in patients with Wolff-Parkinson-White syndrome Right bundle branch block and/or low voltage QRS complex Imaging studies The following imaging[emedicine.medscape.com] Intermittent/paroxysmal supraventricular tachycardia, atrial flutter/fibrillation, ventricular tachycardia Abnormal P waves consistent with right atrial enlargement Prolonged PR[emedicine.medscape.com]
