what is a sine wave ecg Hyperkalaemia is defined as a serum potassium level of 5 2 mmol L ECG changes generally do not manifest until there is a moderate degree of hyperkalaemia
This 12 lead ECG 25 mm sec 10 mm mV of the wide complex tachycardia QRS 240 ms demonstrates the right bundle branch block configuration that evolves The sine wave pattern depicts worsening cardiac conduction delay caused by the elevated level of extracellular potassium The morphology of this sinusoidal pattern

Worsening hyperkalaemia 8 0 9 0 mmol L may precipitate development of a sine wave appearance pre terminal rhythm ventricular fibrillation PEA with bizarre There is a sine wave which is seen with severe hyperkalemia It is sometimes called Ventricular flutter and is also reported with Class I antidysrhythmics
An EKG is an integral part of the initial evaluation of a patient suspected of having a cardiac related problem This activity reviews the basic anatomy and electrical The waves intervals durations and assessment of rhythm is fundamental to ECG interpretation Below follows a brief summary of the ECG waves their appearance
