78 Possible Causes for Hypokalemia, Ventricular Bigeminy

  • Premature Ventricular Contraction

    PVCs can occur in healthy hearts and may simply be a response to: increased catecholamines, caffeine, hypoxia, fever, drug toxicity, hypercalemia, hypokalemia or hypomagnesemia[] Example 3) Ventricular Bigeminy ECG (Example 1) Ventricular Bigeminy ECG (Example 2) Ventricular Bigeminy ECG (Example 3) Ventricular Trigeminy ECG (Example 1) Ventricular[] (low blood levels of potassium), and hypomagnesemia (low blood levels of magnesium), hypokalemia and hypomagnesemia can occur, for example, in patients taking diuretics ([]

  • Cardiomyopathy

    We report a case of a 47-year-old Caucasian woman with medical history of hypertension and hypokalemia, who presented to Emergency Room with symptoms resembling acute coronary[] Frequent ventricular ectopics and ventricular bigeminy (seen with severe DCM). Ventricular dysrhythmias ( VT / VF ).[] Attention to electrolytes is critical to avoid cardiac complications of hypokalemia.[]

  • Hypomagnesemia

    Hypokalemia events were related to malnutrition (odds ratio, 2.79; 95% confidence interval, 1.09-7.14; P .045).[] The patient exhibited sinus bradycardia (48 b.p.m.) with intermittent supraventricular contraction on postpartum day 2, intermittent ventricular bigeminy on postpartum day[] This report describes the case of a 48-year-old man who developed hypocalcemia and hypomagnesemia accompanied by hypokalemia-an interesting finding-following a chemical injury[]

  • Digitoxin

    Digitoxin intoxication was evident, seemingly evoked by hypokalemia, hypomagnesemia, hepatorenal dysfunction and hypothyroidism.[] The frequency of ventricular bigemini, polymorphous ectopies, couplets, more than 30 ectopies/h, salvos and tachycardias (10 vs 9 patients) on and off digitoxin was about[] In both patients, digitoxin was discontinued and hypokalemia was corrected. In patient 1, lidocaine hydrochloride and phenytoin sodium also were administered.[]

  • Caffeine

    Excessive ingestion of caffeine can induce hypokalemia, which affects the neuromuscular system and can lead to paralysis.[] We describe a patient with no previous history of cardiac disease or arrhythmia who developed sustained bigeminy and 2 brief runs of ventricular tachycardia after caffeine[] Excessive intake of caffeine may produce arrhythmias and pronounced hypokalemia and ensuing ventricular fibrillation.[]

  • Digitalis Toxicity

    Dilutional hypokalemia may precipitate digitalis toxicity in the digitalized patient. Successful resuscitation of such a patient is reported.[] bigeminy, and regularized AF.[] Toxicity may result from the cumulative effect of the drug or from hypokalemia.[]

  • Paroxysmal Ventricular Tachycardia

    Furthermore, it typically causes severe hypokalemia, which then leads to muscle weakness and which predisposes to ventricular arrhythmias.[] RVOT non-sustained monomorphic ventricular tachycardia (on the left side) and LVOT ventricular bigeminy (on the right side). Figure 2.[] We describe a dog where albuterol intoxication caused runs of fast paroxysmal ventricular tachycardia that persisted after normalization of the hypokalemia.[]

  • Torsades De Pointes

    He had hypokalemia (K 2.3 mmol/L) induced by licorice and also had received disopyramide for arrhythmia, bicalutamide for prostate cancer, and silodosin for prostate hypertrophy[] […] ablation of incessant right ventricular outflow tract bigeminy.[] Here is review of hypokalemia from the NEJM , but it is mostly about etiology, and says little about rapid replacement in life-threatening hypokalemia EXCEPT to emphasize[]

  • Dofetilide

    Hypokalemia should be corrected before initiation of therapy.[] He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy.[] Of the 36 patients in Group I who started dofetilide before ablation, three stopped it prior to ablation (one for ventricular bigeminy, one for bradycardia, and one due to[]

  • Hypokalemia

    External links [ edit ] Low potassium (hypokalemia) Low Potassium (Hypokalemia) Low Potassium (Hypokalemia) Content of[] Hypokalemia is a common clinical disorder caused by a variety of different mechanisms.[] During follow-up, 507 cases of hypokalemia occurred in 13, 328 patients.[]
