* Hypertension is the most common finding in acute aortic dissection.* Fusion beats are a QRS complex with hybrid morphology of a sinus beat and an intraventricular beat resulting from impulses from two different locations activating the ventricle. One of the impulses is typically ventricular and the other is typically supraventricular.* Nitrate therapy works by reducing both the preload and afterload by dilating veins, coronary arteries, and systemic arteries. It works by relaxing vascular smooth muscles.* There are five cyanotic congenital heart lesions. Remember the 5 T’s and the 1-5 mnemonic: one for truncus arteriosus, two for transposition of the great vessels, three for tricuspid atresia, four for Tetrology of Fallot, and 5 for total anomalous pulmonary vascular return (TAPVR).
