sine wave ecg definition This is the sine wave rhythm of extreme hyperkalemia This pattern usually appears when the serum potassium levels are well over 8 0 mEq L Had we seen the earlier ECGs we

Sinus tachycardia sinus rhythm with resting heart rate 100 bpm in adults or above the normal range for age in children Sinus bradycardia sinus rhythm with resting heart rate 60 bpm in adults or As depolarization merges with premature repolarization there may be Q T shortening and apparent ST segment elevation or the classic sine wave ECG Thus

A very wide QRS complex up to 0 22 sec may be seen with a severe dilated cardiomyopathy and this is a result of diffuse fibrosis and slowing of impulse conduction In addition the T waves are Development of a sine wave pattern As K levels rise further the situation is becoming critical The combination of broadening QRS complexes and tall T waves produces a

Sine wave pattern in hyperkalemia is attributed to widening of QRS with ST elevation and tented T wave merging together with loss of P wave and prolongation of PR interval The waves intervals durations and assessment of rhythm is fundamental to ECG interpretation Below follows a brief summary of the ECG waves their appearance
