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[rnceus.com] Example 3) Ventricular Bigeminy ECG (Example 1) Ventricular Bigeminy ECG (Example 2) Ventricular Bigeminy ECG (Example 3) Ventricular Trigeminy ECG (Example 1) Ventricular[healio.com] (low blood levels of potassium), and hypomagnesemia (low blood levels of magnesium), hypokalemia and hypomagnesemia can occur, for example, in patients taking diuretics ([studynursing.blogspot.com]

  • 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[ncbi.nlm.nih.gov] Frequent ventricular ectopics and ventricular bigeminy (seen with severe DCM). Ventricular dysrhythmias ( VT / VF ).[lifeinthefastlane.com] Attention to electrolytes is critical to avoid cardiac complications of hypokalemia.[clinicaladvisor.com]

  • Hypomagnesemia

    Hypokalemia events were related to malnutrition (odds ratio, 2.79; 95% confidence interval, 1.09-7.14; P .045).[ncbi.nlm.nih.gov] The patient exhibited sinus bradycardia (48 b.p.m.) with intermittent supraventricular contraction on postpartum day 2, intermittent ventricular bigeminy on postpartum day[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov]

  • Digitoxin

    Digitoxin intoxication was evident, seemingly evoked by hypokalemia, hypomagnesemia, hepatorenal dysfunction and hypothyroidism.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] In both patients, digitoxin was discontinued and hypokalemia was corrected. In patient 1, lidocaine hydrochloride and phenytoin sodium also were administered.[ncbi.nlm.nih.gov]

  • Caffeine

    Excessive ingestion of caffeine can induce hypokalemia, which affects the neuromuscular system and can lead to paralysis.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] Excessive intake of caffeine may produce arrhythmias and pronounced hypokalemia and ensuing ventricular fibrillation.[ncbi.nlm.nih.gov]

  • Digitalis Toxicity

    Dilutional hypokalemia may precipitate digitalis toxicity in the digitalized patient. Successful resuscitation of such a patient is reported.[ncbi.nlm.nih.gov] bigeminy, and regularized AF.[calsprogram.org] Toxicity may result from the cumulative effect of the drug or from hypokalemia.[medical-dictionary.thefreedictionary.com]

  • Paroxysmal Ventricular Tachycardia

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

  • 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[ncbi.nlm.nih.gov] […] ablation of incessant right ventricular outflow tract bigeminy.[ncbi.nlm.nih.gov] 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[hqmeded-ecg.blogspot.com]

  • Dofetilide

    Hypokalemia should be corrected before initiation of therapy.[pdr.net] He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy.[ncbi.nlm.nih.gov] 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[academic.oup.com]

  • Hypokalemia

    External links [ edit ] MayoClinic.com: Low potassium (hypokalemia) MedicineNet.com: Low Potassium (Hypokalemia) eMedicineHealth.com: Low Potassium (Hypokalemia) Content of[en.wikipedia.org] Hypokalemia is a common clinical disorder caused by a variety of different mechanisms.[ncbi.nlm.nih.gov] During follow-up, 507 cases of hypokalemia occurred in 13, 328 patients.[ncbi.nlm.nih.gov]
