High potassium t wave changes
WebEarly cardiac changes include tall, peaked, “tented” T waves, followed by loss or flattened P wave, widening QRS, ST-segment depression, bradycardia, sine wave QRS-T, first-degree atrioventricular block, ventricular tachyarrhythmias, and finally cardiac arrest if the potassium levels continue to increase. WebNov 12, 2008 · Potassium levels below 3,0 mmol/l cause significant Q-T interval prolongation with subsequent risk of torsade des pointes, ventricular fibrillation and sudden cardiac death. Potassium levels above 6,0 mmol/l cause peaked T waves, wider QRS komplexes and may result in bradycardia, asystole and sudden death.
