48 Possible Causes for Carpopedal Spasm, Potassium Decreased, Syncope

  • Hyperventilation

    In extreme cases it may cause carpopedal spasms, a flapping and contraction of the hands and feet.Factors that may induce or sustain hyperventilation include: physiological[en.wikipedia.org] This leads to increased plasma protein binding of the serum potassium and a decrease of the physiologically active ionized calcium.[flexikon.doccheck.com] We present the case of a patient who presented with recurrent syncope.[ncbi.nlm.nih.gov]

  • Acute Hyperventilation

    spasm.[emedicine.medscape.com] This leads to increased plasma protein binding of the serum potassium and a decrease of the physiologically active ionized calcium.[flexikon.doccheck.com] Abstract The effects of increasing respiratory rates on arterial pH, PaCO2, HCO3, and potassium (K) were measured in normal anesthetized dogs.[ncbi.nlm.nih.gov]

  • Hypokalemia

    Case presentation We report a case of a 4-year-old girl presenting carpopedal spasm and rhabdomyolysis due to severe hypokalemia associated to hypophosphatemia and hypovolemia[ncbi.nlm.nih.gov] New data make clear that feedforward homeostatic responses activate when decreased potassium intake is sensed, even when plasma potassium concentration is still within the[ncbi.nlm.nih.gov] One patient (a 38-year-old female) had experienced recurrent episodes of syncope due to ventricular tachyarrhythmias (VTAs) accompanied by QT prolongation (QTc: 750ms) when[ncbi.nlm.nih.gov]

  • Metabolic Alkalosis

    spasm (Trousseau sign) depressed respirations (b/c of compensation trying to hold CO2) paralytic ileus (gut shuts down to hold HCO3) ABGs (increased pH and HCO3) decreased[quizlet.com] Serum chloride: Decreased, less than 98 mEq/L, disproportionately to serum sodium decreases (if alkalosis is hypochloremia). Serum potassium: Decreased.[nurseslabs.com] Symptoms of intravascular volume depletion, such as lightheadedness, dizziness, decreased oral intake, syncope or palpitations should be elicited.[clinicaladvisor.com]

  • Respiratory Alkalosis

    Signs include hyperpnea or tachypnea and carpopedal spasms. Diagnosis is clinical and with ABG and serum electrolyte measurements. Treatment is directed at the cause.[msdmanuals.com] According to classical data, serum potassium decreases during the acute respiratory alkalosis.[alpfmedical.info] spasm Shift 02 dissociation curve to the left (Alkalosis) (Increased affinity of Hb for O2) Correction Treat underlying cause Re-breather mask References and Links Acid-Base[lifeinthefastlane.com]

  • Hypomagnesemia

    A 39-year-old woman was presented to the emergency department complaining of severe watery diarrhea and carpopedal spasm after ingesting a handful of magnesium hydroxide tablets[ncbi.nlm.nih.gov] A lack of magnesium inhibits reuptake of potassium, causing a decrease in intracellular potassium. This decrease in intracellular potassium results in a tachycardia.[en.wikipedia.org] CASE PRESENTATION: We describe a case of magnesium wasting in a middle-aged woman with head and neck cancer who presented with recurrent syncopal episodes complicated by a[ncbi.nlm.nih.gov]

  • Hypocalcemia

    Manifestations include hyperactive deep tendon reflexes, chvostek's sign, muscle and abdominal cramps, and carpopedal spasm.[icd9data.com] […] to hypoxia and/or acidosis Cell destruction - crushing injuries, burns and hemolysis Inadequate Potassium Excretion - from decreased aldosterone related to Adrenalectomy[web.archive.org] Acute hypocalcemia may lead to syncope, congestive heart failure, and angina due to the multiple cardiovascular effects.[physio-pedia.com]

  • Heat Exhaustion

    Without treatment, heat syncope can put you at risk for heat stroke.[orthoinfo.aaos.org] Syncope due to standing for long periods in the heat (heat syncope) may occur.[merckmanuals.com] Weakness, fatigue, and fainting are the chief symptoms of heat syncope.[orthoinfo.aaos.org]

  • Hypokalemic Periodic Paralysis

    A 17-year-old female presented to us with a history of perioral numbness and carpopedal spasms of one week duration followed by progressive weakness of all the four limbs[sjkdt.org] […] supplements decreased the frequency of muscle weakness attacks.[ncbi.nlm.nih.gov] We report a rare case of a patient with a novel SCN4A mutation who presented, on ECG, extreme bradycardia and syncopal sinus arrest that required a temporary pacemaker implant[ncbi.nlm.nih.gov]

  • Anterior Pituitary Hypofunction

    Severe hypocalcemia may present with carpopedal spasm, laryngospasm, tetany, and seizures.[revespcardiol.org] Elevated potassium; decreased sodium; elevated blood urea nitrogen (BUN) levels due to decreased glomerular filtration rate. Low blood glucose.[brilliantnurse.com] […] presenting signs and symptoms included headache (63%), vomiting (50%), visual field defects (61%), ocular paresis (40%), mental deterioration (13%), hyponatremia (13%), and syncope[cancer.gov]
