Cardiac arrest in hyperthermia and malignant hyperthermia

…are typically needed. Table 1. Grading of hyperthermia. Body temperature should decrease at a rate of 0.1°C/min during the cooling process. Malignant hyperthermia…

Lung function and respiration

…age, height and ethnicity — not against absolute figures. Since 2022 the z score with a lower limit of normal at z = −1.64 (the…

Cardiac amyloidosis

…Heightened awareness is essential in patients with severe aortic stenosis, particularly the low flow, low gradient phenotype, or those undergoing aortic valve replacement [1, 5…

Posterior Myocardial Infarction: Diagnosis on the Standard ECG

…or posterolateral infarction. Its recognition is clinically important because posterior infarction may not produce conventional ST segment elevation in the standard 12 lead ECG. Instead…

SGLT2 Inhibitors for Cardiovascular and Renal Protection

…the S3 segment. SGLT2 also mediates proximal tubular sodium reabsorption, with chloride following passively down the resulting electrochemical gradient. By inhibiting SGLT2, these drugs produce…

Aortic stenosis

…term outcomes. Patients with low flow low gradient aortic stenosis (discussed below) have a 3 year survival rate of 50% ( Eleid et al ). The cause…

Pulmonary regurgitation

…in the parasternal short axis view. Pressure gradient and pressure half time (PHT) are also estimated using continuous Doppler. A dense regurgitant jet with rapid…

Pulmonary stenosis

…pressure (PA pressure, PASP) can be estimated by subtracting the pressure gradient across the valve (ΔP) from right intraventricular pressure. The systolic PA pressure…

Tricuspid stenosis

…of tricuspid stenosis. Yet, there is no consensus regarding grading of tricuspid stenosis severity. Tricuspid stenosis is visually characterized by thickened leaflets, with reduced motion…

Blood gas interpretation: quick reference for acid-base disorders

…gas describes the physiology at the moment of sampling, but does not by itself identify the cause. The result must always be weighed together with…
