S1 and S2 are valve closure soundsS1 and S2 are valve closure sounds S3 and S4 are ventricular soundsS3 and S4 are ventricular sounds Murmurs are generated whenever there is Murmurs are generated whenever there is

turbulent flow in the heart. Blood flow is generally turbulent flow in the heart. Blood flow is generally laminar and uniform as it moves through the heart. laminar and uniform as it moves through the heart.

The ElectrocardiogramThe Electrocardiogram

The ECG (EKG) is a recording of the The ECG (EKG) is a recording of the electrical potentials produced by cardiac electrical potentials produced by cardiac tissue. These electrical potentials are what tissue. These electrical potentials are what causes the fibers to contract. These causes the fibers to contract. These electrical impulses spread throughout the electrical impulses spread throughout the body and can be recorded on the skin by body and can be recorded on the skin by applying electrodes at various points on the applying electrodes at various points on the surface.surface.
