Hyperkalaemia ECG changes • LITFL • ECG Library
6 days ago · 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 (≥ 6.0 mmol/L). The earliest manifestation of hyperkalaemia is an increase in T wave amplitude. ECG features of hyperkalaemia. Peaked T waves. P wave widening/flattening, PR prolongation.

May 1, 2016 · 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.
ECG changes due to electrolyte imbalance (disorder)
If the hyperkalemia is very severe, the QRS complex may fuse with the T-wave and form a so-called sine wave. This is certainly alarming because sine wave pattern usually precedes ventricular fibrillation.
Sine-Wave Pattern Arrhythmia and Sudden Paralysis That …
Jul 3, 2007 · 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 into and from a sine-wave pattern.
Sine wave pattern - wikidoc
The sine wave pattern depicts worsening cardiac conduction delay caused by the elevated level of extracellular potassium. The morphology of this sinusoidal pattern on ECG results from the fusion of wide QRS complexes with T waves .

Jul 4, 2024 · [1] Peaked T-waves: Narrow, pointy, prominent T-waves. Often this is the most notable finding on the ECG (may be visible on bedside monitor as well). [2] Ventricular tachycardia mimic: QRS wave widens and P-waves may disappear. If patient is tachycardic, this may look like ventricular tachycardia.
An Electrocardiographic Sine Wave in Hyperkalemia
May 10, 2012 · Abstract. A 62-year-old man with chronic renal insufficiency reported having reduced exercise tolerance for the previous week. The physical examination was unremarkable, but oxygen saturation was...
ECG Diagnosis: Hyperkalemia - PMC - National Center for …
Typical ECG findings in hyperkalemia progress from tall, “peaked” T waves and a shortened QT interval to lengthening PR interval and loss of P waves, and then to widening of the QRS complex culminating in a “sine wave” morphology and death if not treated. 1 – 3 Treatment of life-threatening hyperkalemia focuses on blocking the effects ...
Hyperkalaemia | ECG Changes | Calcium | Geeky Medics
Jun 23, 2024 · ECG changes in hyperkalaemia. An ECG is an essential investigation in the context of hyperkalaemia. Abnormalities can include: Tall tented T waves (early sign) Prolonged PR interval; Flattened P waves; Wide QRS complexes; Sine wave pattern (late sign) Arrhythmias
Severe Hyperkalemia With Sine Wave ECG Pattern
Apr 1, 2015 · Serum potassium (measured in mEq/L) is normal when the serum level is in equilibrium with intracellular levels. High serum potassium can lead to alterations in the waveforms of the surface electrocardiogram (ECG) and cardiac death unless treated promptly.
