Hypokalaemia
Hypokalaemia
Hypokalaemia causes typical ECG changes of widespread ST depression, T wave inversion, and prominent U waves, predisposing to malignant ventricular arrhythmias
ECG Interpretation: Other cardiac conditions
Part five of a 5 part lecture series on ECG/EKG Interpretation with Dr Theo Sklavos and cardiologist A/Prof William Wang.
ECG Case 101
51 yr old female who presented with chronic vomiting. She has a history of rheumatoid arthritis and paroxysmal atrial fibrillation. Her medications include sotalol and rivaroxaban.
Hypokalaemic Periodic Paralysis
Hypokalaemic Periodic Paralysis; rare channelopathy; muscle weakness/paralysis with a matching fall in K+ levels; starts in adolescence; weakness may be mild -> full body paralysis
Hypokalaemia
Hypokalaemia: the most common electrolyte abnormality in hospitalised patients; mostly caused by drugs and GI disease
