Ellis-van Creveld syndrome is an autosomal recessive disorder with single atrium as the hallmark cardiovascular defect, seen in 60% of the cases.

Phlebotomy is often resorted to in patients with cyanotic congenital heart disease and symptoms of hyperviscosity syndrome due polycythemia.

ECG, Respiration and SpO2 tracings

Pulse oximetry is the measurement of oxygen saturation in arterial blood by using a non-invasive device, usually connected to one of the fingers.

Nebivolol and beta 3 mediated cardioprotection: Probable mechanism: eNOS activation resulting in the release of nitric oxide and vasodilation.

Beta 3 adrenoceptors are stimulated only at high concentration of catecholamines and act as protection from overstimulation by catecholamines.

Out of hospital cardiac arrest is an important mechanism of death through out the world and the survival rates are poor even in those who are resuscitated.

ACE Inhibitors and anemia: Multiple mechanisms proposed, including suppression of erythropoietin production

Pulsoximetry tracing of ventricular premature complex with a lower amplitude than the normal sinus beat and the following beat with higher amplitude

Invasive blood pressure monitoring is fairly common in acute care setting, using a small cannula in radial artery connected to a pressure transducer system.
