![]() ![]() Cardiac arrest in special circumstances: Electrolyte abnormalities, poisoning, drowning, accidental hypothermia, hyperthermia, asthma, anaphylaxis, cardiac surgery, trauma, pregnancy, electrocution. European Resuscitation Council Guidelines for Resuscitation 2010 Section 8. Treatment of acute hyperkalaemia in adults ECG finding are neither specific nor sensitive for detecting hyperkalaemia (3).the longer a patient has high potassium concentrations, the greater the risk of sudden deterioration (1)Ĭlick here for an example ECG and further information.risk of arrhythmias increase with potassium values > 6.5 mmol/L and even small elevations in potassium above this concentration can lead to rapid progression from peaked T waves to ventricular fibrillation or asystole.cardiac arrest (pulseless electrical activity, ventricular fibrillation/pulseless ventricular tachycardia, asystole) (2)ĮCG changes with hyperkalaemia do not consistently follow a stepwise, dose-dependent pattern.If the rise in serum potassium continues unabated, the heart. arrythmias including bradycardia, ventricular tachycardia or fibrillation Hyperkalemia and Hypokalemia Narrow and tall peaked T wave (A) is an early sign of hyperkalemia.S and T wave merging (sine wave pattern).first degree heart block (prolonged PR interval).Hyperkalaemia causes a rapid reduction in resting membrane potential leading to increased cardiac depolarization, and muscle excitability which in turn causes EG changes (1).ĮCG changes are usually progressive and may include: Last edited 02/2018 and last reviewed 10/2022
