All About Cardiovascular System and Disorders

Atrial septal defect (ASD) is one of the commonest congenital heart diseases in the adult.

Electrical Storm: Frequent fast rhythms originating from the lower chambers of the heart requiring implantable cardioverter defibrillator shocks (>3/day).

U wave is a wave in the ECG (electrocardiogram) which occurs after the T wave and is usually seen in the mid precordial (chest) leads.

Sinus arrhythmia is the variation in the spontaneous rate of the sinus node (natural pacemaker of the heart), resulting in variation of heart rate.

Any rhythm without a pulse can be called a pulseless electrical activity (PEA).

Crux of the heart: Junction of the atrioventricular and inter ventricular grooves behind the heart.

Coronary arteries are blood vessels supplying oxygenated blood to the heart. Two coronary arteries, right and left, arises from the root of aorta.

Left ventricular diastolic function assessment by echocardiography usually on mitral inflow velocity measurement with demonstration of E/A reversal.

Right ventricular conduction delay by itself cannot cause a heart attack. Right ventricular conduction delay can occur with and without a heart attack.

Cardiac catheterisation laboratory is the place where angiography (imaging of blood vessels and the heart) and interventions are done.
