TAPESCRIPT:

Your heart is a __________(1) muscle that pumps oxygen and nutrient rich blood throughout your body. __________(2) beat is stimulated by electrical signals that pass through the heart muscle, or myocardium.

In order to __________(3) the function of your heart, a doctor may perform a test called an ECG or electrocardiogram.

During this test, electrodes placed on the chest are used to make __________(4) of the heart's electrical signals.

These signals follow a set pathway through the heart beginning at a __________(5) called the SA node in the top right chamber, or atrium.  The signal then  branches out through both atria, which contract pushing blood into the lower  chambers, or ventricles.

The electrical signal also __________(6) into the ventricles via the AV node and travels down the tissue that separates these two chambers. __________(7) the signal travels back up the ventricles, which contract, pumping blood to the  lungs and body.

Often, a patient will be __________(8) to perform a stress test during an  ECG. A stress test, which usually __________(9) walking or running on a treadmill at progressively increasing intensities, __________(10) a doctor to examine the heart's electrical activity during the stress of exercise. Variations from the  normal electrical pattern may indicate __________(11) to the heart due to a heart attack, for example.
