67 Possible Causes for Hypoxia, Short PR Interval, Sudden Cardiac Death

  • Myocardial Infarction

    Sudden cardiac death (SCD) is a severe burden of modern medicine.[ncbi.nlm.nih.gov] 10 minutes of hypoxia and a sustained activation that starts after two hours of hypoxia. 113 In this model, ERK2 and JNK are not activated.[dx.doi.org] Primary outcomes Sudden cardiac death.[doi.org]

  • Acute Myocardial Infarction

    Crossref PubMed Virmani R, Burke AP, Farb A, Sudden cardiac death, Cardiovasc Pathol, 2001;10:275–82.[uscjournal.com] The Pathophysiology of Myocardial Infarction Myocardial infarction ("heart attack") is the irreversible damage of myocardial tissue caused by prolonged ischemia and hypoxia[cvpharmacology.com] cardiac death may occur.[ncbi.nlm.nih.gov]

  • Chronic Obstructive Pulmonary Disease

    […] a known risk factor for cardiac mortality and sudden cardiac death. 11 The Lung Health Study investigators reported a RR for hospitalisations due to supraventricular tachycardia[doi.org] Presence of chronic hypoxia or cor pulmonale.[patient.info] Because of low cardiac output, however, the rest of the body suffers from tissue hypoxia and pulmonary cachexia.[emedicine.medscape.com]

  • Lown-Ganong-Levine Syndrome

    If not corrected quickly, the ventricles can fibrillate causing VF ( ventricular fibrillation ) – leading to sudden cardiac death (SCD).[dictionnaire.sensagent.leparisien.fr] Hypoxia, hypercarbia, or acidosis must be prevented because all these complications render cardiac muscle membranes unstable and ectopic depolarization more likely.[accessanesthesiology.mhmedical.com] The PR interval is short.

  • Atrial Tachyarrhythmia with Short PR Interval

    If not corrected quickly, the ventricles can fibrillate causing VF ( ventricular fibrillation ) – leading to sudden cardiac death (SCD).[dictionnaire.sensagent.leparisien.fr] Hypoxia, hypercarbia, or acidosis must be prevented because all these complications render cardiac muscle membranes unstable and ectopic depolarization more likely.[accessanesthesiology.mhmedical.com] Five additional family members had short PR intervals with normal QRS, and eight other family members had borderline short PR intervals.[ncbi.nlm.nih.gov]

  • Ebstein Malformation

    Sudden cardiac death.[patient.info] […] raised concentration of circulating catecholamines in pregnancy will exacerbate any predisposition to arrhythmias; major arrhythmias may occur specifically during maternal hypoxia[apicareonline.com] 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]

  • Barth Syndrome

    Ventricular arrhythmia, especially during adolescence, can lead to sudden cardiac death. There is a significant risk of stroke.[orpha.net] Eur Heart J 34 : 2618–2629 [ PubMed ] [ Google Scholar ] Strogolova V, Furness A, Robb‐McGrath M, Garlich J, Stuart RA (2012) Rcf1 and Rcf2, members of the hypoxia‐induced[ncbi.nlm.nih.gov] A recent electrocardiogram (ECG) was essentially unremarkable ( Figure 1 ), showing in sinus rhythm a slightly short PR interval (0.12 ms), and mildly high voltage QRS, in[revespcardiol.org]

  • Syncope

    cardiac death.[ncbi.nlm.nih.gov] This is a brief lapse in consciousness caused by transient cerebral hypoxia (diminished oxygen).[healthcentral.com] So here goes: W is Wolff-Parkinson-White syndrome – look for a short PR interval or delta wave: O is obstructed AV pathway – look for 2nd or 3rd degree block: or axis deviation[resus.me]

  • Cardiac Arrest

    Sudden cardiac death (SCD) is a sudden, unexpected death caused by a change in heart rhythm ( sudden cardiac arrest ).[webmd.com] We present the unusual case of complete neurologic survival after prolonged hypoxia, severe acidosis, out of hospital cardiac arrest, and exposure to high levels of carbon[ncbi.nlm.nih.gov] interval may identify a subgroup of patients with LV dysfunction, some of whom may benefit from dual-chamber pacing with a short(er) AV delay. 72 These same principles also[circ.ahajournals.org]

  • Ventricular Tachycardia

    Sudden cardiac death in the United States, 1989 to 1998 . Circulation 2001; 104 ( 18 ):2158-2163 [ PubMed ] 26. Kannel WB, Wilson PW, D'Agostino RB, Cobb J.[ncbi.nlm.nih.gov] Abstract Seizures can be difficult to distinguish from other causes of transient cerebral hypoxia in the emergency department.[ncbi.nlm.nih.gov] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[practicalclinicalskills.com]
