lengthened ST
7
Q
Hyperkalemia symptoms
A
MURDER
Muscle weakness
Urine output (little to none)
Respiratory failure (due to muscle weakness)
Decreased cardiac contractility
Early: muscle twitches/cramps
Rhythm changes: Tall peaked T waves, prolongued PR
8

Hyperkalaemia causes
A
The body CARED too much about K Cellular movement (burns, tissue damage) Adrenal insuffiencieny (addisons) Renal failure Excessive intake Drugs (spironolactone, ACEi, NSAIDs)
