Hyperkalemia on ECGHyperkalemia is an elevated blood plasma potassium concentration, generally considered clinically significant starting from approximately 5.0–5.5 mmol/L according to various laboratories and guidelines.
Severe Hyperkalemia and Sine WaveThe sine wave pattern is a terminal ECG pattern of severe hyperkalemia in which the P wave disappears, the QRS complex markedly widens and merges with a tall peaked T wave, forming a smooth…
Hypokalemia on ECGHypokalemia on ECG is a set of ventricular repolarization changes that occur when blood potassium levels drop below normal.
Hypercalcemia on ECGHypercalcemia is an elevated blood calcium level, which manifests on the ECG as shortening of the QT interval.
Hypocalcemia on ECGHypocalcemia is a decreased blood calcium concentration, which may manifest on the ECG as prolongation of the QT interval.
Hypomagnesemia on ECGHypomagnesemia is a serum magnesium concentration below laboratory reference values (roughly less than 0.70 mmol/L), which affects electrical…
Hypermagnesemia on ECGHypermagnesemia is an elevated serum magnesium concentration above normal.
Hypothermia on ECGHypothermia on ECG is a set of electrocardiographic changes when core body temperature drops below 35 °C (hypothermia).
Hypothyroidism on ECGHypothyroidism on ECG is a set of nonspecific changes caused by decreased thyroid function (hypothyroidism).
Hyperthyroidism on ECGThyrotoxicosis is a syndrome of excess thyroid hormones in the blood; hyperthyroidism is a variant thereof caused by increased synthesis and secretion of hormones by the thyroid gland itself.
Electrolyte Disturbances on ECGElectrolyte disturbances on ECG are changes in waves, intervals, and segments caused by shifts in potassium, calcium, or magnesium concentrations, affecting repolarization and conduction.
