متن کاملElectrocardiographic Manifestations and Clinical Outcomes of Severe Hyperkalemia: Can the Electrocardiogram Risk Stratify for Short Term Adverse Events?
Hyperkalemia produces cardiotoxicity through early depolarization of the cell membrane, slowing of ventricular conduction and decreased duration of the action potential. As a patient’s potassium rises, standard teaching describes the sequential appearance of classic electrocardiographic (ECG) abnormalities. Initially peaked T waves are observed. Next, the PR interval prolongs, followed by QRS p...
متن کاملHyperkalemia and atrial pacemakers: what can the electrocardiogram tell you?
A 73-year-old white male with a history of coronary artery disease, congestive heart failure, diabetes mellitus, and pacemaker/implantable cardioverter defibrillator placement presented to the emergency department with a chief complaint of abnormal laboratory tests. On arrival, he complained of nausea, vomiting, diaphoresis, and shortness of breath. Physical examination revealed pulmonary rales...
متن کاملSevere Hyperkalemia: Can the Electrocardiogram Risk Stratify for Short-term Adverse Events?
INTRODUCTION The electrocardiogram (ECG) is often used to identify which hyperkalemic patients are at risk for adverse events. However, there is a paucity of evidence to support this practice. This study analyzes the association between specific hyperkalemic ECG abnormalities and the development of short-term adverse events in patients with severe hyperkalemia. METHODS We collected records of...
متن کاملAcute hyperkalemia leading to flaccid paralysis: a review of hyperkalemic manifestations
Hyperkalemia can present with a spectrum of clinical manifestations with progressive EKG changes and life-threatening arrhythmias. Although no formal guidelines exist as to when to initiate treatment for hyperkalemia, it is generally recommended in clinically symptomatic patients with or without EKG changes. Timely diagnosis and reversal can relieve symptoms and prevent life-threatening arrhyth...
