13 Possible Causes for Absent Knee Reflex, Paresthesia, Premature Ventricular Contraction

  • Hypokalemia

    The earliest signs are weakness and muscle cramps and numbness and tingling that usually begin in the lower extremities.[medical-dictionary.thefreedictionary.com] Ventricular arrhythmias such as premature ventricular contractions, torsades de pointes, ventricular tachycardia and ventricular fibrillation can also occur [ 8 ] .[patient.info] Ventricular arrhythmias such as premature ventricular contractions, torsades de pointes, ventricular tachycardia and ventricular fibrillation can also occur [ 8 ].[patient.info]

  • Electrolytes Abnormal

  • Hyperkalemia

    […] symptoms Patients with hyperkalemia may be asymptomatic, or they may report the following symptoms (cardiac and neurologic symptoms predominate): Generalized fatigue Weakness Paresthesias[emedicine.com] Ectopic rhythms are due to enhanced automaticity, reentry, or both, and may include the following: Nonparoxysmal junctional tachycardia Extrasystole Premature ventricular[emedicine.medscape.com] Rare unifocal premature ventricular contractions were noted in 5/7 patients in the albuterol protocol and in 2/7 patients in the control protocol during the last 2 hours of[doi.org]

  • Charcot-Marie-Tooth Disease

    Sensory loss is often identified when the doctor tests for deep tendon reflexes, such as the knee jerk, which are reduced or absent in CMT patients.[web.archive.org] Patients also complain of numbness and tingling in their feet and hands, but paresthesias are not as common as in acquired neuropathies.[doi.org] Cardiac conduction problems including heart block and arrhythmias (atrial flutter, premature ventricular contractions) have been previously reported including one report in[apicareonline.com]

  • Hyperkalemic Periodic Paralysis

    Weakness can be accompanied by glove-and-stocking paresthesias.[ncbi.nlm.nih.gov] […] arrhythmia may segregate in females Symptoms: Syncope; Suden death Arrhythmia Bigeminy Bidirectional ventricular tachycardia Increased Q-T interval (Early) Premature ventricular[neuromuscular.wustl.edu] […] complete heart block, Mobitz type II second-degree atrioventricular block, ventricular tachycardia, ventricular fibrillation and asystole, muscle cramps, weakness, paralysis, paresthesias[jpharmacol.com]

  • Familial Periodic Paralysis

    He denied any pain or paresthesia. Prior to this episode, the patient had been healthy and denied any recent diarrhea, chest pain, shortness of breath, or weight change.[casesjournal.biomedcentral.com] His baseline ECG showed QT prolongation (680 ms) and premature ventricular contraction bigeminy ( Figure 1 A).[circ.ahajournals.org] Weakness can be accompanied by glove-and-stocking paresthesias.[ncbi.nlm.nih.gov]

  • Hypermagnesemia

    The symptoms depend on the serum concentration of magnesium and may include muscle weakness, facial paresthesias, and in severe cases, cardiac arrest.[symptoma.com] ventricular contraction, which resolved spontaneously within a few days.[jamanetwork.com] Facial paresthesia. Muscle weakness. Decreased tendon reflexes. Disturbances in blood clotting. Constipation (paralytic ileus). Nausea. Vomiting. Headache. Lethargy.[healthhype.com]

  • General Anesthesia

  • Hypokalemic Periodic Paralysis

    Before cardiac side effects would occur, osmotic diarrhea and paresthesia of the lips, hands, and feet typically intervene.[translational-medicine.com] […] arrhythmia may segregate in females Symptoms: Syncope; Suden death Arrhythmia Bigeminy Bidirectional ventricular tachycardia Increased Q-T interval (Early) Premature ventricular[neuromuscular.wustl.edu] Others complain of paresthesias and cognitive impairment (described by patients as mental dullness, fogginess, inability to concentrate, or confusion) from acetazolamide.[translational-medicine.com]
