322 Possible Causes for Bradycardia, Miosis

  • Organophosphate Poisoning

    Human poisoning due to amitraz may be misdiagnosed as organophosphate/carbamate (OPC) toxicity, since amitraz poisoning shares several clinical features (miosis, bradycardia[ncbi.nlm.nih.gov] After a deliberate ingestion of malathion, a 55-year-old male suffering from miosis, somnolence, bradycardia, muscular fasciculations, rales on auscultation, respiratory insufficiency[ncbi.nlm.nih.gov] […] nicotinic symptoms, and late admission were significantly higher than Group 1 (p CONCLUSIONS: Independent predictors of mortality in patients with organophosphate poisoning as bradycardia[ncbi.nlm.nih.gov]

  • Brain Stem Herniation

    Cushing’s triad of signs includes hypertension, bradycardia and apnea. Dr.[emsworld.com] […] insipidus Tonsillar Cerebellar tonsil below the foramen magnum Coma Apnea Hypertension Upward Flattened quadrigeminal cistern "Spinning top" midbrain Hydrocephalus Coma Miosis[derangedphysiology.com] They may have nystagmus, pupillary dilatation, bradycardia, hypertension and respiratory depression.[hawaii.edu]

  • Cholinergic Crisis

    The much shorter “Triple B” only stands for Bradycardia, Bronchospasm, and Bronchorrhea.[symptoma.com] Other symptoms include increased sweating, salivation, bronchial secretions along with miosis (constricted pupils).[en.wikipedia.org] Other symptoms include increased sweating, salivation, bronchial secretions along with miosis.[wikidoc.org]

  • Clonidine Poisoning

    Bradycardia can be treated with atropine sulfate, epinephrine chloride, dopamine hydrochloride, or tolazoline hydrochloride.[ncbi.nlm.nih.gov] All patients were lethargic on admission and most were admitted with bradycardia or miosis. Hypotension was more likely to develop after admission.[ncbi.nlm.nih.gov] Symptoms included altered level of consciousness (n 11), miosis (n 5), bradycardia (n 8), hypotension (n 5), apnea and respiratory depression (n 6), hypothermia (n 5) and[ncbi.nlm.nih.gov]

  • Myocardial Infarction

    We describe a 41-year-old man who presented with steep down-sloping ST-segment elevation, paroxysmal ventricular tachycardia, severe sinus bradycardia, and intermittent complete[ncbi.nlm.nih.gov] […] ethanol, opiates Hallucinogenic Hallucinations, psychosis, panic, fever, hyperthermia Amphetamines, cannabinoids, cocaine Narcotic Altered mental status, slow shallow breaths, miosis[doi.org] On occasion the physician may order atropine sulfate with morphine to counteract serious bradycardia.[medical-dictionary.thefreedictionary.com]

  • Physostigmine

    Bradycardia and salivation were not a problem. One child vomited once. Atropine was not necessary.[ncbi.nlm.nih.gov] Because the size of the pupil is under the antagonistic control of the sympathetic and parasympathetic systems, drugs affecting either system can cause miosis.[ebi.ac.uk] None demonstrated response and, further, there were associated adverse events, including atrial fibrillation (2), pulmonary infiltrates (1) and significant bradycardia (1)[ncbi.nlm.nih.gov]

  • Carbamate Poisoning

    ECG may reveal tachycardia or rarely bradycardia.[symptoma.com] Dyspnea and vomiting were the most common symptom and miosis and cyanosis were the most frequently observed signs.[ncbi.nlm.nih.gov] […] insecticides that inhibit cholinesterase activity, causing acute muscarinic manifestations (eg, salivation, lacrimation, urination, diarrhea, emesis, bronchorrhea, bronchospasm, bradycardia[merckmanuals.com]

  • Exposure to Nerve Gas

    (At this point in the treatment, bradycardia, if it was present, should also have been reversed; miosis will not be reversed by systemic atropine) If breathing has stopped[besurvival.com] Atropine sulfate blocks the muscarinic effects of acetylcholine that cause bronchorrhoea, hypersalivation, bronchoconstriction and bradycardia, thereby reducing these effects[emro.who.int] These include, intense constriction of the pupils (miosis) and severe eye pain, constriction of the bronchioles producing labored breathing, nausea and vomiting, lacrimation[sites.duke.edu]

  • Beta-Blocker Toxicity

    Both patients presented with profound bradycardia and cardiogenic shock. The effectiveness of intravenous glucagon administration is demonstrated in the first case.[ncbi.nlm.nih.gov] Clonidine overdose can mimic opioid intoxication with decreased respirations, miosis, and somnolence.[toxikonconsortium.org] Effects on the ECG Sinus bradycardia . 1st degree , 2nd degree and 3rd degree AV block . Junctional bradycardia . Ventricular bradycardia.[lifeinthefastlane.com]

  • Accidental Hypothermia
